Clearbit (HubSpot Breeze Intelligence)
Clearbit was a B2B marketing and sales intelligence platform; HubSpot acquired it in late 2023 and has rebranded most capabilities as HubSpot Breeze Intelligence. Legacy Clearbit REST APIs (Enrichment, Reveal, Prospector, Discovery, Risk, Logo, NameToDomain) were widely used; new sign-ups are now redirected into HubSpot's product surface, and standalone Clearbit APIs are being sunset for new customers.
