Clearbit
B2B data enrichment platform revealing company and contact data for faster lead qualification.
What it does
Clearbit (now part of HubSpot) is a B2B data enrichment platform that enhances lead and contact records with company and contact intelligence - automatically populating fields like company size, industry, tech stack, funding status, and job title from a partial email or domain. AI capabilities include real-time website visitor deanonymization that identifies which companies are visiting a website, form shortening that auto-fills known fields to increase conversion, lead scoring enrichment that improves model accuracy by adding firmographic context, and intent signal detection. Clearbit's enrichment APIs power many of the personalization and routing workflows in modern GTM stacks.
Why AI-ENHANCED
Clearbit is an established B2B data enrichment platform that has integrated AI-powered deanonymization, intent detection, and real-time enrichment into a mature data intelligence product.
Best for
Mid-market RevOps teams use Clearbit to enrich inbound leads automatically - appending company and contact data to CRM records the moment a form is submitted, enabling faster routing and more relevant follow-up.
Enterprise marketing operations teams use Clearbit as the data enrichment backbone for their GTM stack - powering lead scoring, account-based advertising targeting, and sales routing logic with accurate firmographic data.
Limitations
Clearbit's acquisition by HubSpot has raised questions about its standalone product future — non-HubSpot customers should evaluate how the integration roadmap affects their use case.
Clearbit's data is strongest for US technology companies — smaller companies, non-US businesses, and niche industries may see lower enrichment match rates and less complete data.
Clearbit's API pricing based on enrichment volume can become significant for organizations enriching large databases or high-velocity lead flows.
Alternatives by segment
Clearbit pricing is not publicly disclosed following HubSpot acquisition. Previously volume-based API pricing. HubSpot customers may access Clearbit features as part of existing HubSpot contracts.
