Headless primitives for GTM engineering.
OpenFunnel presents a set of agent-ready GTM primitives for building account discovery, TAM, research, and signal workflows. Its site describes both REST access and an MCP endpoint for agents.
The API details below are not linked to a current official developer page. Confirm them with the vendor before implementation.

This is a GTM-data and signal layer intended to be called by coding agents or incorporated into an in-house GTM-engineering workflow, rather than a conventional list-building interface.
Teams with GTM engineering capacity that want to build agent-driven account discovery and live-signal workflows around their own ICPs.
OpenFunnel says it is optimized for high-context, trigger-based GTM rather than generic high-volume lead-list sourcing. Teams that need a finished, conventional lead-database workflow without agent or engineering involvement should look elsewhere.
No curated rival set covers this tool yet, so these are simply other tools in the same architectural layer and product form. Treat it as a starting point, not a shortlist.
It is positioned as agent-ready GTM primitives for account discovery, TAM building, research, and live signals.
No. Its own agent-readable material says it is optimized for high-context, trigger-based GTM rather than generic high-volume list sourcing.
Yes. The DIY plan names Claude Code, Codex, and Cursor, and the site frames the product as headless primitives for GTM engineering.
Its published material describes a REST base URL, API-key headers, and endpoints for account search, batch account retrieval, ICPs, audiences, timelines, and alerts.
The vendor's agent-readable material describes a native MCP endpoint using OAuth 2.1 with dynamic client registration.
The DIY plan is free with 50,000 starting credits; Enterprise / Custom pricing is custom.
