"Is there another way I can do this?"

That's a question I ask myself all the time. If you're here, that means you're the same. You like having options because B2B sales is all about options-it's about making yourself look like the best option while searching for better options. And while Clearbit has positioned themselves as one of the major giants in sales and marketing intelligence, the truth is they aren't the only option you have.

Great news. You don't have to do the legwork. I've done it for you. I present to you, a summary of 18 Clearbit Alternatives!

TL;DR Table

Obligatory disclaimer: I've done my best to crosscheck the information here but every company has a different way of presenting their information and it changes over time, so I have to put a few disclaimers here.

1. The average rating is an average across G2, Capterra, and Trustradius. Data accuracy is always going to be an issue with all these platforms so please take complaints and praises of data accuracy with a grain of salt.
2. I'm only comparing the lowest prices of each service per month for 1 single user, without any sorts of discount codes/referrals, etc. Most of these companies offer long contracts so you will probably get a better deal with annual plans.
3. Some companies only mention 'company profiles' and some mention 'personal profiles'. I mark personal profiles/contact information with a '*' as these tend to have higher numbers than company profiles.
4. The refresh rates refer to whatever I can find on the company websites, but they may not be a reflection of whether their data is accurate or not.

What does Clearbit do?

At their core, Clearbit is an all-in-one sales intelligence platform that gives you information on your current clients and potential clients.

Still confused? I'll break it down for you.

So you need to sell your product. It's homemade artisan ice cream. Currently, you have a grand total of 2 shops who resell your ice cream. But you want to take your business to the next level. You want to sell more ice cream, to more people, to bigger companies. How do you do that? You need information.

Companies like Clearbit take a look at your existing customers i.e. that one corner store who stocks your homemade ice cream in their tiny freezer, and the coffee shop on the next block who sells hipster coffee, and then compares it with their list of shops. Then they tell you, "Hey, there are two more hipster coffee shops and three mom-and-pop stores in the area, why don't you ask them if they want to stock your ice-cream?"

Sure, you could have walked around the block casing all the coffee shops and local grocery stores, making your own list, and then going up to them one by one, asking to meet the owner. But that would have taken a lot of time. And the chances are, they might not be interested and you wouldn't find out until you got there.

Sales intelligence platforms like Clearbit reduce the amount of legwork you have to do because they have a giant database of company information. They can give you a list of companies that are similar to the ones already in your current customer base. On top of that, most of them can give you the direct contact information of the people who make the decisions. So instead of having to ask someone to "Get me your manager", you can get a phone number or email directly from Clearbit and contact the person easily.

In recent years, Clearbit has expanded their offerings to include a multitude of other sales tools - like telling you who's been searching up 'homemade ice-cream' near you, browser extensions that connect you to ice cream aficionados around the world, and AIs that can help you write emails about why your ice cream is the tastiest one on the block.

Clearbit Pricing

All this is sounding a little too good to be true. Which it probably is. There's no such thing as a free lunch and Clearbit's menu doesn't have any prices. After digging through some of the internet, it seems that their basic package starts at $99. That's a little steep for startups and small businesses! If you head over to their G2 (4.4/5), Capterra (4.4/5), and Trustradius (8.1/10) reviews, you might notice that some people aren't quite as satisfied with their interface and the quality of their data.

But don't worry, you've got options! I'm gonna give you 18 Clearbit competitors that you should consider.

Proxycurl

Are you a developer? Are you looking for an API solution that will get you fresh B2B data at scale? It's us. We got your back. I'm not going to pretend that Proxycurl is a full-fledged alternative for Clearbit or some of the other companies listed here.

We don't have dashboards telling you how many people are looking at your website. We don't analyze your customers and suggest ICPs with an algorithm. We don't write emails for you and tell you when you should call or text a prospect.

Instead, we're a fully self-managed REST API that pulls fresh, raw B2B data for your applications.

You want to search for companies in your ICP? We have a Company Search API Endpoint. Want to look for people in your buyer personas? We have the Person Search API Endpoint. Need to track job changes of prospects? We wrote about it here on how to track their job changes programatically. Found an email, can't find the person? Use our Reverse Email Lookup Endpoint. Or maybe you found the person, but can't find their contact information. Our Contact API can get those for you.

Our data enrichment API products is fully compliant with the GDPR and CCPA data and privacy laws, and is also in the process of getting SOC2 Type 2 certified.

Where does this data come from? It's updated daily from public profiles pulled from major sites like LinkedIn and Crunchbase, that's why we guarantee that the information is less than 29 days old.

If you need a more comprehensive lead list with more data, Proxycurl offers up LinkDB. It's an exhaustive dataset of all the close to 500M of profiles we have. You can buy it at a standalone price, or choose to get quarterly updates to ensure your data keeps up with global changes. The best thing is that you can segment the data according to your needs so you don't end up with profiles from a different part of the world that you're never going to target.

Proxycurl ratings and reviews (3.9/5.0)

Proxycurl is rated 3.9 on G2. Most regular B2B companies tend to go for full service platforms over pure developer REST APIs so we don't have a lot of reviews yet. (Maybe you can leave us one after you test our API with 100 free credits?)

Most of our customers are satisfied with how fast and easy to use our API, (Thanks dev team!) and how it does exactly what it says it will. Most of the developers like our documentation. It's easy to read!

The biggest complaint about Proxycurl so far is that we only have annual plans paid by monthly installments, which I understand, is not everyone's cup of tea.

Proxycurl pricing

Proxycurl has both annual (paid in monthly installments or in one lump sum) and pay-as-you-go (PAYG) plans. The starter annual plan averages out to be $49/month with 2500 credits.

I think this is pretty straightforward. You get 2500 credits every month and they expire after 30 days. The amount of data enrichment you can pull wholly depends on which parameters you use because some are premium parameters that consume 30 credits per profile returned, and some of them just cost 1 credit.

But maybe you don't want to commit just yet. That's okay! We have PAYG plans starting from $10 for 100 credits.

Credits on the PAYG plan don't expire unless your account has been inactive for more than 18 months so you don't have to rush to finish them all in a month. Start with 800 or so, test it out, and then buy more as you need them.

Who should try Proxycurl?

Companies looking for an easy-to-use REST API for their B2B data enrichment needs. OR developers who want the code, nothing but the code, and the whole code without having to pay exorbitant or opaque prices to access APIs.

Sapiengraph

Okay, so you're NOT a developer and everything I said in the previous section made your eyes glaze over. You just want to search for leads and enrich data. You want something you can just jump into without spending 5 hours on uploading or syncing data from your regular CRMs.

Well, Sapiengraph is the home of 5 minute growth tools, easy tools that you can start using immediately without extensive know-how.

Right now, we have a prospector tool. You can search for CEOs, CTOs or any other key-decision makers via your dashboard. Just fill out the filters, hit enter. You can even choose to return only profiles with emails or personal numbers attached.

Sapiengraph also has a browser extension that allows you to use custom Google Sheet formulas, and a free job change monitor. You can get B2B data immediately in your own spreadsheets without having to learn how to use a new platform.

If you want to monitor someone's employment, all you need to do is enable the extension and click monitor job change on their LinkedIn profile. You can monitor up to 20 profiles for free!

Sapiengraph ratings and reviews

Our review page is waiting for you to try out our growth tools and leave your comments.

Sapiengraph pricing

Sapiengraph has monthly plans that start at $49 for 12500 credits that expire every billing period.

12500 credits can get you anywhere from 150 to 250 enriched leads. You can try it out with 100 free credits just by signing up for an account. Please note that the type of enrichment you perform consumes a different amount of credits! You can see how much each formula costs in our API documentation.

Who should try Sapiengraph?

Companies and people who love spreadsheets and easily get overwhelmed by long setup processes that some other alternatives require before you can get the full value of their services.

ZoomInfo

If you've heard of Clearbit, then you've probably heard of ZoomInfo. They are one of the more well-known Clearbit competitors out there. It's pretty large in its own right. They have an all-in-one platform that gives their users information on who to reach and how to reach them.

Like Clearbit, ZoomInfo started out as a B2B company data provider. Over time, they expanded to cover all aspects of business management like marketing, operations, data services, and talent management.

If you're running a big business and you're tired of using 5 or 6 different providers to manage your sales, marketing, operations, data, and talent, you might want to consider ZoomInfo. Their comprehensive tools and extensive integrations mean that you can use them with your existing CRMs and other tools easily. Perfect if you've already gotten other parts of your business set up the way you like it.

Not only do they have an extensive database, (1.3B companies recorded, 100M published), they also have features like advanced search filters and an AI copilot. Included in their extensive search filters is something called Scoops that allows you to get really, really specific about what you're searching for. And I do mean specific.

Their AI copilot also helps you to stay on top of your pipeline by suggesting actions for you to take in a timely fashion.

While other data providers may refresh their data points a few times a month, ZoomInfo says that they refresh data points on a daily basis. While this doesn’t preclude the possibility of having outdated information, they have a pretty solid track record of great data.

ZoomInfo ratings & reviews (4.2/5)

Right off the bat, we can see that the company is pretty highly rated on G2, Capterra, and Trustradius.

ZoomInfo has an average rating of 4.2. Not a surprise because they bring a lot to the table.

However, because of the vast amount of features they have, users can sometimes get lost or frustrated by the amount of effort needed to get everything set up in the initial stages. There’s a bit of a learning curve (as with any large product) and users have reported feeling frustrated with the lack of customer support available.

ZoomInfo pricing

Like Clearbit, ZoomInfo doesn’t list their prices on their website. Cue, chorus of groaning from introverts around the world.

You have to get in touch with their sales team in order to figure out a custom package because they tailor their prices according to how many features you want to use and how many people in your company need access to the platform.

The good news is that you can sign up for only the features that you want. However, Will Aitken (Co-Founder of Sales Feed)mentioned that getting access to their data enrichment tools easily costs about $1000 a month, making it pretty much unaffordable for small businesses.

Who should try ZoomInfo?

Large enterprises that are looking for an all-in-one solution and are scaling up their sales should definitely look into ZoomInfo for their data enrichment needs. For mid-sized and smaller companies, you can keep scrolling!

Apollo.io

Apollo.io is another popular end-to-end platform for sales teams out there. Unlike Clearbit and ZoomInfo which aim to become a comprehensive all-in-one solution for businesses, Apollo is more focused on the sales pipeline. Boasting 275M contacts from all over the world, they have a pretty large database of company information.

If you’ve got existing CRMs or systems in place, you don’t need to worry because Apollo.io works with many of the popular platforms like Salesforce and Hubspot.

Apollo updates data signals like job changes or emails and phone numbers in real time, and runs monthly refreshes of their database to ensure that data accuracy.

They do a great job with workflow automation, letting you create something known as ‘Sequences’. These sequences let you automate multi-step processes for sales outreach like sending emails and making calls.

Like ZoomInfo, Apollo.io has an AI writing assistant that helps you create personalized emails for your prospects.

The AI writing assistant has a pretty helpful section in their personalization settings. You don’t need to manually prompt the AI, just fill in the empty boxes with the pertinent information and the AI will do the rest!

Personally, I was intrigued by Apollo’s in-built dialer. You don’t need to pick up your phone or type in numbers because Apollo can do it for you!

Users from inside the US and Canada can use local numbers whereas users from other countries will have to request international phone numbers. International numbers are only available on certain plans so make sure you get the right one!

Apollo.io takes their regulations and compliance seriously so using their in-built dialer requires a lot of documentation. Check their requirements so that you don’t miss out on any!

Apollo.io ratings & reviews

Apollo.io is pretty well-received and has an average rating of 4.5 across G2, Capterra, and Trustradius.

Overall, users like Apollo.io’s intuitive interface and multiple integrations, particularly Bombora, which shows buying intent. Sales teams spent less time on trying to find email addresses or phone numbers and more time moving their leads through the pipeline instead.

Other users have run into issues with data accuracy, which is a common issue for all data providers when you’re crawling the interwebs for billions of contact data.

Apollo.io pricing

I’d like to thank Apollo.io for having a transparent pricing structure on their page. They have a free plan which is perfect for testing the waters. Their free plan comes with unlimited email credits (Yes you heard that right, it’s unlimited!), 60 mobile credits, and 120 export credits that are renewed every year. It’s not a lot for businesses that are aiming to pull in 50–100 sales a month, but it’s a good starting point for a startup.

Apollo.io’s most basic plan comes in at $49 per month for each user, which is still within the realm of affordable, and also gives you the option to add on credits if you run out at one point.

Who should try Apollo.io?

Small to mid-sized companies who only want a sales management solution can benefit from getting Apollo.io. Their affordable price and flexible credit system makes it easier to scale up as you go and they’re considerably easier to navigate compared to the vastness of bigger platforms!

Cognism

Do you need three times more live conversations? That’s what Cognism promises to bring you. This UK based company says that they can connect you to 87% of your leads list because they verify all their contact numbers!

“Oh c’mon, surely all B2B databases verify contact information?”

Most of them do, but not all of them verify the numbers via phone. Cognism has something called Diamond Data where they verify the validity of their contacts by calling each of them one by one. Might sound a little crazy, but that’s what they do.

As a result, they have a huge database of global direct dials and 98% of their mobile numbers are verified by humans. If you notice that one of your contacts hasn’t been verified, you can even request verification and Cognism will let you know if the contact is valid within 48 hours. They redial the numbers every year and a half (18 months) to make sure that the contacts are still valid and viable. Before you go rushing off to sign up though, just know that Diamond Data is only available on the enterprise plan!

Another one of Cognism’s boasts is their compliance. They have compliance teams that ensure their data aligns with the ISO 27001 and SOC2 frameworks. They are certified for ISO 27001, ISO 27701, and also SOC2 Type II.

Cognism takes GDPR compliance pretty seriously. Not only do they tell their database about their information being in Cognism, they make sure that their data always complies with the latest international privacy standards. Besides that, Cognism cross-checks their database with global no-call registries so that you can reach your leads without worrying about privacy or legal issues. However this does mean that they don’t provide personal emails, but rather work email addresses only.

Use LinkedIn frequently? Cognism also has a browser extension that can help you export data right into your account from public LinkedIn profiles!

Both Cognism’s platform and extension work with popular CRM tools available in the market like Salesforce and Hubspot so you can integrate it into your workflow right away.

Cognism ratings & reviews (4.3/5)

Overall, Cognism has a 4.3 across three websites. That’s a pretty decent score.

Overall, users have mentioned that Cognism is pretty easy to pick up and integrate into their existing workflows. Customers based in the US mention that the quality of Cognism’s data is pretty good.

However, one thing that Cognism could stand to improve (according to other clients) is their global data. They seem to do well when it comes to the UK and the US but data accuracy drops in other countries, especially in Asia. If you’re thinking about expanding towards the east, you might have to look elsewhere for your data needs.

Generally speaking, Cognism responds pretty quickly to issues that pop up on their platform, making them pretty easy to work with. Props to their customer service team!

Cognism pricing

Cognism doesn’t list their prices on their website. Like some of the other Clearbit alternatives here, they prefer to give every customer an individual price that depends on the type of licenses or the number of features they want.

Unlike Clearbit and other competitors however, they have a platform access fee. Essentially, you pay one price for the data, and another to use the platform. The fee is supposed to cover maintenance, set-up, onboarding, and customer service for the platform.

I found a review that mentioned that Cognism started from about 20000 EUR/year for 100 users, which is akin to 185USD per user, per month. It’s not a thousand bucks, like ZoomInfo and some of the other available options, but it’s not exactly cheap either. Generally, it’s only a great option if you have the budget to spare.

Another thing to note is that Diamond Data (the human-verified phone contacts) is only available to people on the Enterprise plan, so if you’re signing up for that, you might be paying a hefty price.

Who should try Cognism?

Mid to large sized companies with the budget for Diamond Data whose target is the US and UK market, and uses cold calls as their primary outreach. Not every company reaches out via phone call nowadays. If that’s you, then feel free to move on to another data provider. However, if you prefer connecting via mobile, their human-verified phone numbers are a good investment.

Lusha

Another Clearbit alternative you can consider is Lusha. Lusha doesn’t have the biggest database in the B2B industry, but they make a claim for the most accurate database

How do they do it? Basically Lusha has a community program that collects contact information from their client’s databases. If you opt to join this program, you give them access to your business emails and they cross-check the data you have in yours, with the data they have in theirs. Through this community program, Lusha ensures that the data they collect is accurate and reliable so you can double your connect rates.

I get that it sounds a little scary, but please be assured that Lusha only accesses professional business data like email headers and signatures to validate and consolidate data. The community program also removes outdated information so that clients can get up to date data.

In accordance with privacy laws, Lusha notifies each professional of their data being collected and gives them instructions on how to manage or remove their profiles.

Lusha is GDPR and CCPA compliant and maintains SOC 2 Type 2, ISO 27001, and ISO 27018 certifications so you don’t need to worry about accidentally calling someone on a DNC list.

Lusha also tracks intent data for you and makes it easily available in both contact and company view.

Lusha uses Bombora’s company surge to see how many people at a particular company are researching a topic, how often they read about it, and how long they spend on the topic. They analyze that data to create an intent score to tell you what a company currently has in mind. The moment you open a contact or company card, you can see their intent signals.

They might not have as many features as the giants in the industry, but they’re definitely one of the sales intelligence tools to consider.

Lusha ratings & reviews (4.1/5)

Lusha has a pretty decent rating of 4.1 and plenty of reviews so far.

Lusha has their fair share of supporters. Most of them say that they found integration quite easy. While their desktop UI seems to be pretty intuitive and easy to use, other users have expressed dissatisfaction with their mobile interface because it doesn’t work as fast as expected. Sales teams that want to prospect on the go might want to look elsewhere for their tools.

Lusha pricing

Lusha has four plans, the lowest one being the Pro plan at $49 per month, per user.

The amount of contact information you can get is dependent on your credits, which isn’t stated clearly in the pricing plans. If you’re on a higher plan and decide to downgrade, prepare to lose all the credits you haven’t used. Some users have said that the amount of data they get from Lusha is worth less than the price they pay, especially when it comes to the non-US market.

Who should try Lusha??

Small to mid businesses who are just getting started in the global market. If you’re an enterprise user, you might want to look elsewhere because their credit system starts to eat up at costs as you scale up.

Lead411

Lead411 is just over a decade old and is making great waves in the B2B data market. It’s pretty similar to Cognism and Lusha if you’re looking for alternatives for those two. They cover marketing and recruiting in addition to sales if you’re looking for something that’s more comprehensive.

Lead411 also offers a browser extension, intent data, and API along with numerous integrations with existing CRMs.

They’re still primarily a lead intelligence software platform that provides contact data to sales and marketing teams. If you need some actionable information, they provide access to intent data from Bombora.

Lead411 lets you choose something they call topics. You can choose to track topics like industries, competitors, or specific technology. So if your company sells medical instruments, Lead411 can keep you updated about which companies are currently looking to purchase medical equipment. It can also help you determine which of your customers are looking at alternatives so you can reduce your churn.

Set your worries at ease with double verified phone numbers and triple verified emails. Lead411 verifies their contact data manually by calling or emailing the numbers or addresses one by one.

For phone numbers, Lead411 verifies each one twice, once by manually dialing the numbers to make sure the right person picks up. The second time is done by looking up the location of the number to see if it matches the recipient.

As for emails, Lead411 checks the validity of the emails in their databases through SMTP and seeing if mail sent to that address is opened. They also have an AI to find the best possible matches for missing emails. Lead411 also reverifies these contacts every 3–6 months, ensuring that you get the most accurate information at all times. If there’s an urgent need, you can also request for real-time verification.

Lead 411 ratings & reviews (4.6/5)

At a 4.6 rating, Lead411 is pretty highly rated compared to other products.

As usual, I went to read the reviews so you didn’t have to. Customers have praised Lead411 for their prompt customer service and overall great data. There’s also been notes about they’re pretty much value for money because you get unlimited data for a single price.

Accuracy wise, there are some issues here and there with outdated information as with most data companies. Some users have also expressed that they would prefer to have more filtering options available. Regardless, it’s a pretty decent product worth your money.

Lead411 pricing

You can get Lead411’s Basic Plus Unlimited at $99 per month, per user.

The $99 basic plus unlimited plan comes with unlimited email views and unlimited direct phone number views. They also roll over your unused exports as long as you’re subscribed. If you need more exports, you can purchase them as needed.

But if you’re thinking of subscribing to get their Bombora intent data, you should know that it costs an additional $2500 per user and can only be added onto the Enterprise plan, meaning to say that you have to upgrade your Basic Unlimited plan in order to get the intent data!

Who should try Lead411

Mid to large businesses who need to hit specific sales goals within a specific time frame within the US. They have a limited global database so if you’re looking to expand worldwide, go to the next.

UpLead

Up next is UpLead! With a total of 155M contacts and 16M global company profiles, their database is a smidge smaller than other sales and lead intelligence companies, but they guarantee 95% accuracy.

When you look up email data or contact information, UpLead will then tell you if the information is valid or invalid. 95% of verified, “valid” information is accurate so you can easily contact your leads and increase your sales engagement.

One thing I like about UpLead is the option to download only valid contact data. Your credits only get deducted when you hit the download button, so you can save on credits by only downloading valid information.

They cover 50+ data enrichment points that encompass most firmographic and technographic aspects so that you can upgrade your lead prospecting pipeline. However that extent of enrichment is only available through their Enterprise plan so be warned!

Uplead refreshes their data daily and verifies contact information in real time. They even rank leads according to their freshness so that you can get accurate and up-to-date information at your fingertips.

Their easy no-fluff UI makes it easy for users to get started immediately.

UpLead ratings & reviews (3.65/5)

Uplead ranks lower than the rest of the recommendations on the list with an overall rating of 3.65.

While UpLead promises a lot of accuracy and better B2B lead generation, it seems that a lot of their contacts are outdated. The common complaint across the bad reviews say that their data is outdated compared to other companies and that their customer service is a little lacking. However, there are just as many reviews that claim that the accuracy is decent and that the emails are correctly verified, helping companies to reduce bounce rates.

Still, people have complained about the lack of transparency in their billing system so please be careful when you sign up!

UpLead pricing

All the pricing information is available on UpLead’s website. They have 3 available plans for all your needs.

Prices start at $99 per month for 170 credits that you can use to look up verified email addresses and mobile phone numbers. You can also get their chrome extension for free. Because it’s a credit based system, they don’t base it off the number of seats.

Buyer intent data, more comprehensive CRM integrations, and API access are only available through their custom packages so if you’re looking to use all of these features, you’ll have to give them a call.

Who should try UpLead

Mid-sized companies who place emphasis on accurate leads and have the budget for the enterprise plan, but don’t want to take it further than that. If you’re paying $99 a month to get emails and numbers, you’re better off using Sapiengraph if you’re a Google Sheets fan, or Proxycurl if you like APIs.

RocketReach

RocketReach has rocketed their way into a few lists over the past few years as a great sales intelligence solution.

The platform offers a database with more than 700M person profiles and 60M companies, promising a 98% deliverability rate for their Grade A emails.

RocketReach has a community program as well. When you sign up, it gives RocketReach access to your email contacts so that they can cross check their information against yours.

RocketReach is very careful about being GDPR compliant and will remove data if requested. If that happens, the individual will be struck from their database. They also hide profiles that don’t meet their standards, choosing to offer a fewer number of high quality profiles instead of a large number of low quality profiles.

A lot of companies promise real-time verification and RocketReach does the same. If you use their browser extension on LinkedIn to look up a person, their information will be verified in real-time. Other contacts are refreshed about once a month.

RocketReach also does something called Lookalike Audiences that takes lead prospecting one step further. Basically, they recommend profiles for you based on who you’ve been looking at so that you can grow your network faster.

RocketReach ratings and reviews (4.1/5)

RocketReach stands at about 4.1 on average. They’ve got a pretty loyal customer base so far.

Aside from its affordability (which I’m going to cover in a bit), users praise the ability to scrape fresh data immediately by using their browser extension. Their extension is a hit with most of their users and if you’re someone who spends a lot of time browsing LinkedIn, maybe you can consider RocketReach.

Other users do raise a point in which they say that the number of available integrations should be improved overall.

RocketReach pricing

You can get easy access to RocketReach’s pricing information on their website, with their essentials plan starting at $70 a month per user.

At that price point, you get access to most of the basics that you need like exports, charts, API access, their browser extension and integration with Zapier. You can use Zapier to then integrate RocketReach with other CRM software if you’d like.

However, if you’re looking to integrate this fully into your workflow right off the bat, you’re going to need to get the Pro plan or higher.

Please do note that phone data is only available on plans that are higher than Essentials so companies that operate by cold calling are going to have to get a more expensive plan!

Who should try RocketReach

Mid to large companies who want personal contact information in addition to professional contact information and a pretty high sales target. I feel like 500 emails a day is way too much for anyone to need because we’re looking for quality leads, but your mileage may vary.

Leadfeeder (Dealfront)

With more than a decade in the industry, Leadfeeder is a pretty solid sales tool in the market. At the moment, Leadfeeder’s main attraction is their website visitor identification.

If you want to know who’s lurking on your website, just install the Leadfeeder Tracker script. Leadfeeder runs a reverse DNA lookup to return the hostname of an IP address. They check this against a database of known IPs and tell you exactly who’s visiting your website.

Most of the time, people who are already on your website are hot leads. Chances are that they are pretty far along in their purchasing pipeline so they’re low hanging fruit. Once Leadfeeder figures out who’s been looking at your website, they also add information about how big the company is, what kind of industry they’re from, and where they’re located.

You can also get a bigger, better understanding of what the company is like by retrieving firmographic data using their IP Enrich API.

This API basically retrieves all the information associated with that particular IP address and helps you to understand who exactly is visiting your side and from where.

Leadfeeder ratings & reviews (4.2/5)

On average, Leadfeeder comes in at 4.2 across the three platforms.

There has been mixed reviews about Leadfeeder. Given that it operates mostly upon intent data and IP information, their B2B data enrichment sometimes leaves something to be desired. Users mentioned that the available integrations don’t work as smoothly as they’d like.

Leadfeeder pricing

Very transparent, there are only 2 prices. Either you’re on the free plan where you can see data in the past week and only from 100 companies, or you’re on the paid plan at $99 per month.

One of the things I like is that the free plan only considers identified companies. As in if 10 employees at Company A visit your website a total of 50 times, they will still consider it as 1 company because they have been identified as belonging to Company A.

Who should try Leadfeeder

Large companies looking to convert web visitors into proper leads. It’s a little steep for smaller companies that may not even get that many anonymous visitors, or have trouble doing the outreach to convert these anonymous leads.

6sense

6sense pretty much coined the term Dark Funnel to refer to buyer intent information. They made a name for themselves with regards to predictive analysis based on this invisible, great data (their words not mine!). Basically, they use a combination of first party and third party data to take a look at who’s been lurking on your website and then tell you what to do about that.

Like Leadfeeder (Or maybe it’s the other way around?), they perform reverse IP lookups to identify anonymous website visitors. This way, you can identify about 25% of your web visitors. They also partner with external websites that collect user engagement through cookies, aka what they were doing before they were looking at your website. This also means they cover who’s been looking at industry publications, influence outlets, blogs, product reviews, social media and other places aside from your company website. Combined with AI analysis, 6sense says they can give you a pretty accurate overview of who is actively looking for solutions that you can provide.

Now, they don’t stop at website visitors. 6sense has since expanded to provide B2B Data for all your sales and marketing needs. They refresh their data every 45 to 60 days and add data every single month. Firmographic data and technographic data are updated daily and bi-weekly respectively.

As of now, they track 500B intent signals every month and have published about 65M company profiles worldwide.

I was curious about their verification processes but 6sense doesn’t divulge much. It appears that they use a combination of their own proprietary artificial intelligence and human verification to ensure that the contact data that you get is accurate.

As with many of the Clearbit Alternatives I’ve talked about so far, they have an API that can be integrated into your workflows.

6sense ratings & reviews (4.2/5)

6sense is rated pretty much the same as Leadfeeder at 4.2.

If you head on over to 3rd party review sites, most of them have a decent view of 6sense. In terms of revenue insights and their predictive analytics, 6sense is particularly solid. Some users have mentioned that 6sense doesn’t have a great UI, citing long loading times and a steep learning curve as a turn off. Tech-savvy users probably won’t have too hard of a time, but the process of setting up the service in the first place has a little bit of a learning curve.

6sense pricing

We’re back to no transparent pricing on the website, folks!

I went digging so you don’t have to and so far, it seems prices range from $1000 to $2500 per user, per year. That’s about $80 to $200 a month (give or take a few dollars).

If you’re on the lowest plan, 80 bucks is a decent price. However, if you’re running a small company that needs more users, then things can get a little pricier.

Who should try 6sense

Mid to large sized companies who need a more ABM-focused approach to their sales and marketing. Their buyer intent data and marketing capabilities can help you narrow down exactly where you should be focusing your marketing efforts.

Adapt.io

Adapt.io says that they have the most extensive and precise industry database. Their repository of contact information is currently at 250M+ B2B contacts and they have the company data of about 10M+ companies, their industry, employee count, and revenue. They’ve also got about 250M of B2B contacts that include emails, mobile numbers, and locations.

Adapt has a more extensive database for technology sectors. If you have a particularly niche sector or type of business you want to deal with, you can probably search for it in their existing database.

Adapt.io promises real-time data updates so that you can make better decisions and engage your customers easily. They also claim to have really great customer service on call to answer your questions regardless of time and place.

Adapt.io ratings & reviews (4.0/5)

Adapt.io has an average of 4.0 across three platforms. Not too shabby.

One of the main issues that has been raised is the number of credits in proportion to the price. And given that (like all other platforms) data accuracy and availability can be an issue depending on your industry and geographic location, you might find yourself needing to buy more credits pretty quickly.

Adapt.io pricing

You can see an upfront overview of how many credits you get in each plan, starting at $49 a month.

The starter plan is enough for you to dip your toes in and try out their data enrichment plans. It works well enough for smaller businesses and allows them the opportunity to scale up to a custom package later on. However, if I’m being honest, you can get more credits for the same price with other companies. I recommend testing their free option to see if their data accuracy is worth their limited credits.

Who should try Adapt.io

Mid-sized businesses that want a scalable option for their data enrichment needs. It’s just a little pricey for smaller companies, but a great starting point for those who are already well-established, but want an upgradable option.

LinkedIn Sales Navigator

If you’re in the sales and marketing world, you’ve definitely heard of LinkedIn Sales Navigator. It’s designed to help you prospect and build relationships within LinkedIn.

LinkedIn Sales Navigator isn’t one of the end-to-end platforms I’ve introduced in this article so far. They mainly focus on prospecting via advanced search capabilities, then building connections via their real-time insights and inMail Messaging. It sounds a little plain when compared to the comprehensive solutions that other companies provide.

Anyone who wants the kind of bells and whistles that come with an extensive sales and marketing platform, you can still use LinkedIn Sales Navigator because they have a lot of CRM integrations possible.

Their InMail feature and relationship tracking system sounds quite neat since people are more likely to want to explore a company that has some sort of connection to them, but it might be a hit or miss depending on your niche or industry.

LinkedIn Sales Navigator ratings & reviews (4.4/5)

Beloved by sales professionals all over the world, LinkedIn Sales Navigator averages in at 4.4 on three websites.

I don’t think a lot of people can complain about Sales Navigator. When it comes down to the basics, LinkedIn Sales Navigator does what it says. The only problem is the price point because other B2B data companies provide more with the same price. The fact that every plan gets only 50 InMail messages feels a little criminal to me.

LinkedIn Sales Navigator pricing

If you head to their pricing page, they don’t say much about what it costs, but you can easily unearth their prices elsewhere.

The most basic version of LinkedIn Sales Navigator starts at $99 a month. That’s a little steep for a small business but probably peanuts to someone who’s running a multi-million dollar enterprise.

Their core plan does not come with a lot, but you do get access to their search filters, relationship explorers, and real-time alerts.

Who should try LinkedIn Sales Navigator

Mid-sized companies or larger who are targeting large sales numbers every month. For that price point, you can get a cheaper deal with similar leads

Seamless.ai

They call themselves the first and only real-time search engine for B2B sales leads. Seamless has an artificial intelligence search engine that they say can help you build a pipeline or close more deals.

They have a grand total of 1.9B+ contact data (and counting). Granted, the number is a combination of contact data and company profiles, but that’s still a pretty good number.

Seamless primarily uses AI and machine learning to verify the data they get from companies and uses the same AI to help suggest the right prospects for you.

Seamless also offers an AI writing assistant. If you’re new to writing, this assistant can be pretty decent cause it has a prompt library where you can select the type of writing/script that needs to be done. You can also customize the tone of voice and the information that you want to add in their settings feature.

It does take a little bit of time to set up, but it could be pretty useful for people who do a lot of outreach every single day.

Seamless.ai ratings & reviews (3.7/5)

Seamless scores about 3.7 overall. Not the best compared to the other alternatives I’ve listed here.

From the look of the reviews, they have a decent database that could be improved. When it comes to the product itself, most of the reviews are quite complimentary. However, some users have expressed their dissatisfaction about the lack of transparency in the contract terms regarding the cancellation period.

Seamless.ai pricing

You can test out Seamless’s free plan to get a taste of what they have to offer. They have 50 credits that you can use to access emails or mobile numbers.

Did I go digging again? Yes. Recent reviews have mentioned that they paid around $3000–3800 for a year’s subscription, bringing the average to about $316 a month for what appears to be the Pro plan.

Do take note that their Basic plan comes with 250 credits that are refreshed monthly while the Pro plan and above have daily credit refreshes. Their AI writer is also listed as an Add-On that isn’t included in whatever base price you’re quoted.

Who should try Seamless.ai

Mid to large enterprises. If you’re a small business thinking of the basic plan, you’re probably better off using other services because you get more bang for your buck with more features. For bigger companies who can afford all the add-ons, Seamless is a pretty decent choice.

LeadForensics

LeadForensics leans towards deciphering anonymous website visitors like Leadfeeder and Seamless.

Similarly, they use reverse-IP tracking to match the IPs of website visitors with known company IPs in their database. After they identify who’s been looking at your website, you can use that information to get contact details of these companies and pitch your product in a personalized manner.

If you’ve got an ICP ready, you can upload it to LeadForensics and they’ll send you an alert if someone who fits that ICP visits your website.You can also segment your visitors according to firmographics, making it easier to get a handle on your audience and market.

Where does the contact data come from? Well, LeadForensics gets them from approved third party sources and verifies or enriches them in-house. However, they’re very upfront about not having personally identifying details so if you’re looking for direct personal numbers or emails, this isn’t for you.

LeadForensics is fully GDPR compliant, making them a good choice for businesses who are looking to take things internationally. They don’t have SOC2 Type II certification, but they do have BS EN ISO/ IEC 27001:2017 certification, which means they’ve established, implemented, maintained and are improving their information security management system.

LeadForensics ratings & reviews (4.1/5)

Overall, LeadForensics gets a 4.1 across three sites, which is pretty decent.

According to the existing users, LeadForensics is pretty great at deanonymizing web visitors. It’s got a lot of features, some of which go unused by smaller teams because there’s just too many of them.

However, since they don’t actually have their own database of contact data, you might run into some problems with data accuracy and availability, especially when it comes to global data.

LeadForensics pricing

LeadForensics only has 2 plans at the moment: Essential and Automate.

I went a-looking for prices and found a couple of anecdotes about it being around $260-$500 per month, but then it depends on the volume of your website traffic.

LeadForensics does things a little differently when it comes to customizing packages because your quote will be based on the amount of traffic you see during your free trial. Do be careful about their contract and renewal though, some users have complained about being locked into long contract terms with no way out.

Who should try LeadForensics

Mid to large companies looking for a long term website analytics solution and can afford to commit for 3–5 years. If you don’t want the commitment, maybe it’s better to not!

Demandbase

Demandbase is another Clearbit alternative that gives you access to the identities of your anonymous website visitors, and buyer intent. But not just any intent data, all the intent data. You want Bombora surge? No problem. G2? Sure. TrustRadius? Of course. Use another website for your data? They’ll import it for you.

They don’t stop there though, they use whatever buying signals or intent data they have, and combine it with artificial intelligence and natural language processing. You can keep track of unlimited keywords relevant to your products or your competitors, in 133 different languages. Multilingual sales intelligence tools are less common but Demandbase is one of them!

DemandBase has 150M+ contacts in 195 countries worldwide, curated by their own AI. They don’t promise any sort of accuracy but they have great search functions where you can search by titles so you can get to decision-makers faster.

Now, DemandBase says that their data is sourced from multiple places and validated through AI and machine learning so it’s supposed to be pretty accurate. If it’s not, you can flag the information as wrong so their fully human team can re-verify the info.

Want to keep up with relevant news? Demandbase makes it easier by putting business-relevant news into your feed so that you can stay up to date with topics like financial decisions, real estate deals, operational changes, and leadership changes. If these don’t appeal to you, no worries. You can set up custom trackers to hunt down the most relevant news for your business and search for specific keywords.

Demandbase ratings & reviews (4.3/5)

Demandbase gets an average of 4.3.

The company does pretty well in terms of getting you intent data and deanonning web visitors. There’s mixed reviews about their reporting, with some people saying that they don’t get enough customization, while others say it’s perfectly fine. While Demandbase does come with numerous CRM integration capabilities, reviews have mentioned that the setup takes time and more tech know-how than an average sales person might have.

Some of the reviews have also mentioned the price point as an issue and ended up having to remove it from their workflow. And despite having 133 languages available, it appears that their data isn’t that great in non-Anglophone areas.

Demandbase pricing

Demandbase only does custom packages based on your company’s needs.

Despite my best efforts at unearthing a ballpark figure for you, I must confess the closest I got was $1500 per month for a company of about 200 people. To be very fair, most enterprise plans probably land in the vicinity of that price, but it does deter a lot of smaller companies.

If you have the budget first, their lowest tier does have a nice amount of features like the embedded B2B data, installed tech data, and Plug & Play Partner Integrations. They even cover advertising, making them a great sales and marketing intelligence tool.

Who should try Demandbase

Mid to large enterprises, with emphasis on the large, who are wholly ready to move into accounts-based marketing. Judging from the reviews and the overall offerings, you pretty much need a solid team to set things up and get things going.

LeadIQ (4.0/5)

LeadIQ monitors your buying signals, gives you B2B data, and then helps you write scripts using AI. They have over 600 million contacts across US, EMEA, and APAC, including verified email addresses, mobile numbers, and technographic data.

The data comes from data partnerships, publicly available information, the contact lists of their own customers, and a proprietary algorithm.

The data is verified through a series of checks like their data partner’s own evaluation, followed by real-time verification and then their algorithm. They also rely on LeadIQ’s own users to flag and edit any incorrect contact data, which they’ll re-verify. Some of their data is refreshed and verified in real-time, but I couldn’t find a promise of how fresh their contact information is going to be.

Like other platforms that gather community data, LeadIQ promises only to retrieve data that’s typically found on business cards. They are fully GDPR compliant and users can request that their information be removed at any time.

LeadIQ also has a writing assistant called Scribe. You can get it to generate cold emails or pitches for you. Even their free tier lets you test out the email generations, which is pretty nifty to me.

Not only does it take prompts, you can change the value proposition to personalize the email further for specific decision-makers.

LeadIQ ratings & reviews (4.0/5)

At 4.0 out of 5, LeadIQ is a pretty well-received Clearbit alternative.

The general sentiment is that it does really well if you’re using it in conjunction with LinkedIn Sale Navigator. Not that it doesn’t work without LinkedIn, but just that it might work slower. If you’re prospecting from LinkedIn, there have been complaints that the sync rate is pretty slow, which is frustrating if you’re looking for hundreds of prospects a day.

LeadIQ pricing

You can get the lowest tier of LeadIq at $45 per month, per user.

Their Essentials plan gives you 1000 verified emails and 50 mobile numbers. It’s a decent starting point for any small business starting to do sales outreach. The expense ramps up quickly if you start adding seats, but for smaller companies who might only have one person in sales, it’s good enough.

Who should try LeadIQ

Small to mid-sized companies in their first leg of sales intelligence. It’s got enough to get you off the ground and start running, but not too expensive that it breaks the bank.

FullContact

FullContact boasts 248M people profiles in North America and 200M updates every single day. Not only that, they track 50B identifiers across 10 different categories to produce comprehensive people profiles.

They have access to 224M phone numbers and 125M business emails alone. If I include personal emails, the amount of contact information in their database is doubled. Fullcontact is partnered with Fideo, a company that verifies contact information to protect you from fraud and identity crimes. Basically, whenever you retrieve information, the FullContact platform pulls the data from Fideo through an API and verifies it on the spot.

FullContact links bits of identifiers to a person and assigns them a unique Person ID to create an identity graph. The data is gathered from places like public websites (social media) or business cards (transcribed by humans) and appended to your existing contact database. If you already have a bunch of contacts, you can import them via Excel. Coupled with Google and Yahoo integration, FullContact does a lot to give you a comprehensive profile of a person.

One interesting thing I noted while looking up FullContact was their Mobile Ad IDs aka MAIDs. These IDs track the type of ads that people open on their mobile devices, which makes it easier to figure out user behavior and activity. Useful for segmentation, in my opinion.

FullContact ratings & reviews (4.1/5)

FullContact comes in at an average of 4.1.

In general, it does great with contacts and people like the fact that the information is being refreshed daily. The extension grabs information pretty quickly and accurately, which is a huge plug point.

Unfortunately, a common complaint from users is that the mobile app is kind of buggy and the platform takes some time to sync. The waiting time is quite tedious if a company wants to sync or export thousands of profiles at a time. Though the extension has a bit of a learning curve, don’t let that deter you from using it.

FullContact pricing

There are three plans available for prospective customers of FullContact, the lowest price being $99 per month.

The essentials plan gives you pretty much everything you need for basic lead generation if you’re a small to mid-sized company. You get enough browsing analytics and just enough leads to not overwhelm the team on the essentials plan. I also like that the $99 comes with 3 seats right off the bat.

Who should try FullContact?

Smaller teams who want to identify and contact their website visitors without breaking the bank, or companies who are scaling up really rapidly and want to hit massive KPIs.

TL;DR Features List

At this point I will be blamed if I didn’t create a nice big table telling you what each platform has. But if I put in an extensive list of features, this article would become uncomfortably long (and wide) so I’m just going to give you the top ones like AI writing assistants, API access, privacy compliance, and also buyer intent. Have fun!

Conclusion

Congratulations! You made it to the end of this article!

Here’s that handy tl;dr table again because I know this post is super duper long and you might have forgotten what I said about Proxycurl at the start of this post.

Last thoughts: a huge database doesn’t mean quality data, and live updates aren’t a guarantee of accuracy.

That said, feel free to give Proxycurl or Sapiengraph a whirl before considering all these other Clearbit alternatives. Happy Data Enriching!
