OpenFunnel is a real-time GTM intelligence platform. It monitors your total addressable market 24/7 and surfaces accounts that are actively showing buying signals, so your team reaches out when it matters, not on a random schedule.

Apollo and ZoomInfo give you static lists filtered by basic criteria like company size or tech stack. OpenFunnel runs live agents that detect actual market activity (hiring patterns, competitor engagement, executive moves, LinkedIn behavior) and only flags accounts when there's a clear, verifiable reason to reach out.

A signal is a live, verifiable trigger that indicates a company is in-market. Examples: a company posting its first Head of SOC 2 role, a VP engaging with a competitor's content, or a team scaling hiring for a specific function. These are contextual, not generic, and they come with references and reasoning.

OpenFunnel tracks account-level signals (hiring posts, tech adoption, compliance milestones, expansion moves, competitor activity) and people-level signals (LinkedIn activity, executive interactions with competitors, role changes). You can deploy domain-specific signals unique to your market.

OpenFunnel is built for B2B GTM teams: SDRs, AEs, and RevOps who need quality over quantity and care about reaching accounts at the right time with the right context. It's built for quality-first teams, not high-volume outbound.

OpenFunnel connects with Salesforce, HubSpot, Clay, Slack, and OpenClaw, and supports API, Webhooks, and MCP for AI tools like Claude, Cursor, and many more. You get the data wherever your team already works.

OpenFunnel offers a full API with multiple endpoints, an MCP integration for AI-first workflows, and Webhooks. Teams can build custom GTM workflows using OpenFunnel's data and agents directly.
