Ranked in Data Enrichment Software ·Free plan
About
OpenGTM is an open-source, self-hosted workspace for go-to-market teams, combining lead sourcing, enrichment, AI research, buying signals and outbound workflows. Its workbooks bring together imports, formulas, HTTP columns, provider waterfalls, AI research and output columns, with estimated spend displayed before a run. Teams can segment live audiences, monitor hiring and buying signals, and schedule refreshes and automations. Listed activation destinations include HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, warehouses and consent-gated ad audiences. Users and agents can reach the same workspace through REST, webhooks and an auditable MCP server with scoped read and write capabilities; the MCP guide names several clients, including Claude, Codex and Cursor. The project says data stays on the user's infrastructure and provider calls use keys selected by the user. OpenGTM is free at 0.00 USD per free, though third-party provider costs may apply. Installation calls for Git, Docker with Compose v2 and roughly 4 GB of available RAM. The project describes itself as pre-1.0.
Who it is for
It suits GTM teams that want to run lead sourcing, enrichment, AI research and outbound automation on infrastructure they control. Teams should be comfortable installing Docker-based software and managing provider keys and production security settings.

What to know first
