Clearbit provides B2B data enrichment — appending firmographic, technographic, and contact data to leads from its database of 20 million+ company and 200 million+ contact records. When a prospect submits a form with just their email, Clearbit returns company name, size, industry, technology stack, job title, and contact information — enabling personalised experiences without long form fields.
HubSpot acquired Clearbit in 2023, integrating its data enrichment directly into HubSpot CRM. For HubSpot customers, Clearbit enrichment now surfaces within the HubSpot interface without additional setup — making rich company data accessible to all HubSpot users.
Short form conversion uses Clearbit enrichment to enable minimalist forms — collecting only email and relying on Clearbit to append all other required fields. Shorter forms increase conversion rates; Clearbit makes the data available without requiring prospects to fill in company, title, and role.
Reveal identifies anonymous website visitors by company from their IP address — showing website analytics by target company and enabling personalised experiences for anonymous visitors from known target accounts.
Prospecting API provides access to Clearbit's database for outbound prospecting — building targeted lists by company firmographics and technographics without manual research. For SDRs building lists of companies with specific characteristics (Salesforce customers over 500 employees in financial services), Clearbit provides the data.
Clearbit AI runs as ml platform software built around data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api, with API access for teams that want to embed it into their own products.
