Clearbit is a B2B marketing intelligence company that provides real-time firmographic and technographic data on millions of businesses. Founded in 2014 and headquartered in San Francisco, Clearbit built its reputation on developer-friendly APIs for enrichment and prospecting, and on Clearbit Reveal, an IP-to-company solution that de-anonymizes website traffic so revenue teams can see which companies are engaging with their digital properties.
Over time, Clearbit evolved into a broader data activation platform, combining its enrichment data, Reveal intent signals, and an audience builder that plugs into CRMs, marketing automation platforms, analytics tools, and ad networks. The platform enables demand generation, marketing operations, and sales teams to define their ideal customer profile, build precise account segments, personalize website experiences, and prioritize outreach based on real buying intent. Clearbit’s data set covers tens of millions of companies with 100+ attributes per record, including industry classifications (NAICS, SIC, GICS), employee bands, revenue estimates, location, and technology stack.
The company raised approximately $17M across a seed round and a Series A led by investors such as First Round Capital, SV Angel, Battery Ventures, and Zetta Venture Partners. In November 2023, HubSpot acquired Clearbit and began integrating its capabilities directly into HubSpot’s CRM and marketing suite under the Breeze Intelligence for HubSpot brand. While the Clearbit name and documentation remain widely used in the market, new customers primarily access Clearbit’s data and Reveal-powered intent signals as part of HubSpot’s credit-based enrichment and buyer-intent offerings.
Within the intent data landscape, Clearbit Reveal is known for strong IP intelligence, deep website visitor analytics, and tight integrations with tools like Salesforce, HubSpot, Marketo, Drift, Intercom, Segment, and leading personalization and analytics platforms. It is particularly popular among B2B SaaS and technology companies that want to operationalize first-party website intent data across outbound sales, ABM, and advertising, rather than relying solely on third-party intent feeds.
