HubSpot (NYSE: HUBS) is a 📝Customer Relationship Management (CRM) platform founded in 2006 in Cambridge, Massachusetts, that sells marketing, sales, service, content, and operations software on a shared Smart CRM. It serves businesses from startups to enterprises and connects to more than 2,000 apps through its App Marketplace.
Co-founded by Brian Halligan and Dharmesh Shah, HubSpot went public in 2014; Yamini Rangan succeeded Halligan as CEO in September 2021. In December 2023 it acquired 📝Clearbit for $150 million and later relaunched its data as 📝Breeze Intelligence inside 📝Breeze, the AI suite of assistants and agents billed in HubSpot Credits that moved to outcome-based agent pricing on April 14, 2026. HubSpot now calls itself an agentic customer platform and opens its CRM to outside agents through the 📝HubSpot Agent CLI, a hosted remote MCP server, and the 📝HubSpot Developer MCP Server. Those tools operate records already in the CRM, while dedicated GTM data platforms such as 📝Clay and 📝Cargo focus on sourcing new prospects and multi-provider enrichment.
We keep HubSpot in the library as the contrast to how we actually run outbound. Its agent tooling is strong at operating a CRM, but for finding and enriching prospects at volume we use Clay and Cargo, then push the results wherever the records live.
