🌐 The Open Source GTM OS. A real go to market operating system, opened up so any professional services firm can learn from it and build their own. Most of what you see here is what we, Mabbly, actually run on ourselves. The more we give, the more useful it is to you.
🧩 New to the pieces? Claude Cowork is the AI that does the work. Notion is the workspace it all lives in. GTM for PS is the method that decides what is worth doing. Together they make a GTM operating system. And professional services is different, it runs on relationships you already have, not strangers, so it needs its own system.
🟢 Live and read only. This is not a slide deck. It is a working system. Built with Claude, Notion, and the GTM for PS framework. Last reviewed June 2026.
