I'm Philip, CEO & co-founder of Brew.new, an agentic marketing email platform.
For the past few months, we've been heads down trying to grow Brew. Along the way we tried a lot of tools, workflows and growth hacks. Some worked really well, most didn't. What we kept looking for, and couldn't find, was one place with growth systems that have actually been proven to work, written so an AI agent can run them.
So we built it. growth.engineer is an open-source catalog of growth workflows. Each one is a markdown file that says exactly which tools and MCP calls it uses, so you can plug it into Claude, Cursor or Codex over MCP and run it. It's free and there's no sign-in.
It's important to us that everything on here is high quality and proven. Anyone can contribute a workflow by PR (https://github.com/GetBrew/growth-engineer), but everything goes through a rigorous review before it's merged. If it hasn't worked somewhere real, it doesn't go in.
All credit for designing and building it goes to Thomas Park and Nithin Kumar. Absolute legends.
We'll keep adding what works for us, and hope you'll add what works for you.
