Clearbit Company Enrichment API
Provides company enrichment API for business data insights.
Our take: Originally a standalone REST API delivering firmographic data, tech-stack detection, and revenue estimates, Clearbit was acquired by HubSpot in December 2023 and fully rebranded as Breeze Intelligence.
Best-in-class B2B enrichment dataset, but new buyers must commit to HubSpot — the standalone API is gone.

Best / not good for
- HubSpot CRM users wanting automated firmographic enrichment on inbound leads
- Account-based marketing teams using intent data and tech-stack filters
- Revenue operations teams enriching large contact databases inside HubSpot
- Developers needing a portable, standalone B2B enrichment REST API
- Teams not on (or unwilling to adopt) HubSpot CRM
- Startups or SMBs seeking low-cost pay-as-you-go enrichment outside a full platform
Friction report
Trade-offs to know before signing up.
- Time to valueSlow: requires a HubSpot subscription, workspace onboarding, and Credits configuration before enrichment pipelines run.
- Scale breakpointPer-seat costs compound quickly at 10+ users; large enrichment volumes require purchased credit packs on top of subscription fees.
- Walled gardenHigh: all data pipelines and workflows are locked inside HubSpot — no portable API, no standalone exports for new accounts.
