About Freckle
Freckle is the data and workflow layer for GTM teams. Users tell an agent in Claude, Codex or our app what they want, and Freckle builds and runs it: pulling lists, enriching them across dozens of data providers, scoring with AI agents, and writing results back to the CRM. We compete head to head with Clay and win, and Series A+ teams like Bolt.new run their GTM on us.
