OpenFunnel is a Y Combinator-backed startup building personalized AI agents for go-to-market teams that want to find accounts at exactly the right moment. Traditional prospecting relies on static lists and periodic data refreshes, which means teams often reach out long after a buying signal has gone cold. OpenFunnel flips that model by continuously monitoring a company's total addressable market and watching for the specific triggers that indicate a prospect is in-market.
The platform lets GTM teams define custom signals, the events, behaviors, or changes that suggest a company is a strong fit and ready to engage, and then deploys agents that scan the open web for those triggers in real time. When a signal fires, OpenFunnel surfaces the relevant account and context to the sales team, allowing reps to reach out with timely, relevant messaging rather than generic cold outreach.
Because each agent is tailored to a customer's ideal customer profile and signal definitions, OpenFunnel functions less like a static data vendor and more like an always-on research analyst dedicated to a team's specific market. This is especially valuable for AI-first GTM teams that want to operationalize intent data and trigger-based selling without building bespoke monitoring infrastructure themselves.
OpenFunnel was founded by Fenil Suchak and Aditya Lahiri and is headquartered in San Francisco. The company went through Y Combinator and has raised approximately $1.8 million across two rounds, with its seed round closing in January 2025 backed by investors including Decacorn Capital, NYX Ventures, Transpose Platform Management, and Y Combinator. The funding supports development of its real-time intent detection agents for go-to-market teams.
