In simple English
OpenGTM helps you find customer leads, enrich their contact details, and send them to your sales tools. It runs on your own computer or server so your data stays private. You can connect paid data providers when you need them, but a free demo mode works right away. It replaces expensive commercial prospecting platforms with a tool you control. You need some technical skill with Docker to set it up and keep it running.
What it is
OpenGTM is a self-hosted workspace written in Python and React that manages lead sourcing, enrichment waterfalls, and AI-driven research. It combines a PostgreSQL (a structured database for storing application data reliably) database, a Redis (an in-memory data store used for caching and job queues) message broker, and background workers inside Docker (a way to run a program inside its own sealed box, so it cannot break anything else on your server) containers.
What it is good for
Sales teams and solo founders who want to automate lead research and outbound prospecting without paying monthly subscription fees to cloud-based data enrichment platforms.
- Keeps all your customer and prospect data on your own infrastructure.
- Includes a zero-key demo mode so you can test it without configuring paid APIs.
- Provides an MCP (Model Context Protocol, an open standard for connecting AI models to data sources and tools) server to let AI agents query and update your lead data.
- Requires Docker and command-line knowledge to install and operate.
- Needs about 4 GB of available memory on your server to run smoothly.
- Licensed under the GNU AGPL-3.0 (Affero General Public License, which requires you to share your source code if you offer the software as a hosted service to others), which places conditions on network service providers.
