Founder story
Clearbit was founded in 2015 in San Francisco by Alex MacCaw, Harlow Ward, and Rob Holland. The company was launched to solve rampant data decay in B2B databases by creating a developer-friendly engine that could turn a simple email address into a comprehensive profile. It grew rapidly as a standalone data powerhouse before being acquired by HubSpot in December 2023.
What it does
- Enriches contact and company records with over 100+ firmographic and demographic data points using email or domain inputs
- Identifies anonymous website visitors to reveal the companies browsing a site, enabling targeted account-based marketing efforts
- Provides real-time API access to business data, allowing developers to build custom enrichment and lead-scoring workflows
- Validates email addresses and provides risk assessment signals to reduce fraud and improve outreach deliverability
- Facilitates dynamic website personalization by tailoring content and CTAs based on visitor firmographics and company profile.
Who it's for
