OpenGTM review
A flexible open-source choice for enrichment waterfalls, AI research, and workflow routing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenGTM is an AGPLv3-licensed, self-hosted GTM platform for sourcing leads, enriching company and contact records, researching accounts with AI, tracking buying signals, and routing results to sales tools. It is aimed at teams that want control over enrichment workflows and infrastructure rather than a closed, fixed-purpose data tool. The product is available through the web, API, self-hosted deployment, and a Chrome extension, with a free open-source model.
Its standout capability is the sequential enrichment waterfall. Teams can order providers, stop early when confidence is sufficient, and work across email finding and verification, phone, firmographics, decision-makers, social, technology stack, hiring, IP/domain, and scoring data. AI, research, and goal-directed agent columns extend the workflow beyond static enrichment. Buying-signal detection covers hiring, funding, technology, website, news, growth, and social events, while pre-run cost estimates, provider cost ledgers, and spend ceilings provide visibility into provider usage.
OpenGTM also fits teams that need several routes from enriched data: HubSpot, Salesforce, Google Sheets, Airtable, webhooks, email sequencers, n8n, REST API access, and an MCP server are supported. The main operational consideration is ownership: users run the software on their own infrastructure, supply their own provider keys, and pay connected enrichment and AI providers directly. Choose OpenGTM when open-source control, wide enrichment coverage, programmable interfaces, and configurable waterfalls matter most. Consider another option if you want a fully managed service with provider costs and infrastructure handled in one offering.
