OpenGTM

Product: OpenGTM is an open-source, self-hosted workspace for GTM teams and their agents.
Lead workflow: It sources companies and people, enriches rows through cost-ordered provider waterfalls, researches questions with cited agents, tracks buying intent, and sends qualified records to other tools.
Workbooks: Workbooks support lead imports, formulas, HTTP columns, enrichment waterfalls, AI research, and output columns, with estimated spend shown before a run.
Signals and automation: Live audiences can segment records, watch hiring and buying signals, and trigger scheduled refreshes and automations.
Integrations: The README lists HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, warehouses, and consent-gated ad audiences as activation destinations.
Agent access: The same workspace is accessible through REST, webhooks, and an auditable MCP server with scoped read and write capabilities.
AI tools: The MCP guide says the server supports Claude, Codex, OpenCode, Pi, Cursor, Windsurf, and other stdio MCP clients.
Data control: The project says data stays on the user's infrastructure and third-party calls use provider keys chosen by the user.
Spend controls: The landing page says teams can review an estimate before each run and set a workbook budget that stops paid calls before exceeding its ceiling.
Setup requirements: The repository says installation requires Git, Docker with Compose v2, and roughly 4 GB of available RAM; its demo does not require provider keys.
Supported desktop environments: The README documents laptop installation on macOS, Linux, and Windows using Docker Desktop for Windows.
Security posture: The production checklist calls for production secrets, changed default passwords, TLS termination, and backups of both PostgreSQL and the data volume.
Security reporting: The security policy requests private vulnerability reports through GitHub or [email protected] and says maintainers aim to acknowledge reports within 72 hours.
Maturity and hosting limit: The security policy describes OpenGTM as pre-1.0, while the README says public multi-tenant hosting needs additional work beyond team-controlled Compose deployment.
