What is OpenFunnel?
OpenFunnel is a real-time total addressable market (TAM) intelligence platform designed to replace static lead databases with a dynamic, domain-specific go-to-market (GTM) intelligence layer. Built by a Y Combinator-backed team based in San Francisco, it surfaces accounts at the exact moment buying needs emerge, rather than relying on traditional prospecting timelines. The platform enables users to find companies based on traits and live signals, enrich account data with people and decision-maker information, monitor audience activity, and score accounts based on urgency and relevance. OpenFunnel is optimized for trigger-based GTM workflows and offers nearly complete real-time signal coverage with contextualized insights. It fits sales agents, GTM teams, and businesses seeking a more precise and timely approach to market intelligence and lead discovery.
