OpenGTM is a free, open-source, self-hosted workspace for go-to-market teams and their agents. It sources companies and people, enriches leads through cost-ordered provider waterfalls, researches questions with cited agents, tracks buying intent, and sends qualified records to other tools. Workbooks combine imports, formulas, HTTP columns, enrichment, AI research, and outputs; they show estimated spend before a run and can stop paid calls at a set budget ceiling. 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. Workspace access is also available through REST, webhooks, and an auditable MCP server with scoped read and write capabilities. The project says data stays on the user's infrastructure and provider calls use keys chosen by the user; third-party costs may apply. Installation requires Git, Docker with Compose v2, and roughly 4 GB of available RAM. The project describes itself as pre-1.0, and public multi-tenant hosting needs additional work beyond team-controlled Compose deployment.
