A good Clearbit alternative fills in missing company and contact details, identifies the businesses visiting your website or gives your sales team accurate B2B data to work with. Check data coverage for your markets, how enrichment connects to your CRM, how credits work and how the provider handles privacy rules. This page lists ten options in no particular order.
For years Clearbit was the quiet engine behind a lot of marketing tools, enriching sign-ups with company size, industry and logo. Since it joined HubSpot, teams outside that ecosystem have been looking for other ways to get the same data.
These are ten Clearbit alternatives in no particular order, sorted alphabetically, from data APIs to prospecting databases and website visitor tools. Each description comes from the tool's own website, re-checked today. If you're building a lead engine around this data, my guide to AI for B2B lead generation shows the workflows that turn enrichment into pipeline.

What happened to Clearbit
Here's the background that explains the search. Clearbit's own homepage now says Clearbit has joined HubSpot, and its release notes announced it was sunsetting the public Clearbit Logo API that many sites used to show company logos for free. If your forms, dashboards or product relied on those free pieces, check what still works and plan a replacement before something quietly breaks.
The right Clearbit alternative depends on the job
- Enriching form sign-ups: an API or enrichment tool that connects to your forms and CRM.
- Seeing who visits your site: a website visitor identification tool.
- Finding new prospects: a prospecting database with search filters.
- Building data into a product: a developer-friendly data API.
- Combining sources: a workflow tool that calls several providers.
How to test a Clearbit alternative on your own data
- Export a sample of a hundred recent leads or customers.
- Run the same list through two or three tools.
- Check how many records each tool fills in, and spot-check accuracy by hand.
- Compare results for the countries and industries you sell to.
- Work out how many credits a typical month would use.
Keeping enriched data useful
Enriched data goes stale quickly, because people change jobs and companies change size. Re-enrich important records on a schedule, and keep a field showing when each record was last updated so your team knows what to trust.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Don't enrich everything just because you can. Decide which fields change what you do, such as company size for routing leads or industry for messaging, and pay attention to those. The common traps are covered in my piece on lead generation mistakes.
Privacy and B2B data
Business contact data is still personal data in many countries. Tell people how you got their details, give them an easy way to opt out and only keep what you need. It's the right thing to do, and buyers notice when a company handles their data with care.
Credits, limits and the true size of a free plan
Most data tools sell credits, and free plans hand out a small monthly allowance. Before you choose, work out how many records you'd enrich in a normal month, including new sign-ups, imported lists and re-checks. Then compare that number with each tool's allowance. It's the quickest way to see whether a free plan will last a week or a year.
Watch for what counts as a credit, too. Some tools charge for every lookup, others only for records they successfully fill in. That difference can matter more than the headline allowance.
Do you make B2B data or enrichment software? Tool makers can ask to be considered for a featured place on this list.
My plain advice on choosing a Clearbit alternative
Test with your own leads, not the vendor's demo. The tool with the best coverage for your markets and the cleanest connection to your CRM will save more time than the one with the biggest headline database.
And keep an eye on privacy rules wherever you sell. Good data used carelessly can still cause a problem.
