OpenFunnel

What is OpenFunnel?

OpenFunnel offers headless go-to-market primitives that coding agents and sales teams can call to find and qualify accounts. The building blocks include lookalike search from closed-won accounts, a total addressable market builder from an ideal customer profile, tech-stack search, deep account research against a custom question, hiring and job-post signals, people-moved tracking, LinkedIn and X social signals, and CRM account and contact sync. You can use it from coding agents such as Claude Code, Codex and Cursor, through an API, the web platform, MCP, webhooks or your CRM. The DIY plan starts free with 50,000 credits and no credit card, while the Enterprise or Custom plan adds credit pools, a forward deployed engineer, managed workflows, custom instances and on-prem deployment. The company says it is backed by Y Combinator.
