Clearbit

A leading B2B data enrichment provider, now integrated within HubSpot to deliver real-time intelligence across the CRM and marketing automation ecosystem.

Clearbit, acquired by HubSpot in 2023, is a B2B data enrichment and intelligence platform founded in 2014 and headquartered in San Francisco, California. The platform enables go-to-market teams to enrich leads, identify anonymous website visitors, and build targeted audiences by leveraging a vast database of company and contact attributes. By appending firmographic, technographic, and demographic data to records in real time, Clearbit helps sales and marketing teams prioritize outreach, personalize messaging, and improve conversion rates across the funnel. Within HubSpot's ecosystem, Clearbit's capabilities have been deeply integrated to power smarter CRM data, more precise audience segmentation, and intent-driven workflows. Its core products — including Enrichment, Reveal, and Prospector — allow revenue teams to automatically fill in missing data fields, de-anonymize web traffic, and discover new prospects that match their ideal customer profile. These tools are particularly valuable for B2B companies looking to reduce manual research, improve data hygiene, and accelerate pipeline generation. Clearbit occupies a strong position in the B2B data and intelligence market, competing with players like ZoomInfo, Bombora, and 6sense. Its integration into HubSpot significantly expands its reach and distribution, making enterprise-grade data enrichment accessible to HubSpot's broad customer base. The acquisition underscores the growing importance of first-party and third-party data intelligence in modern go-to-market strategies, and Clearbit's technology continues to serve as a foundational layer for data-driven revenue operations.
