Seeking advice on reaching ROS 2 developers

I’ve spent the last few months building 𝗝𝗼𝗶𝗻𝘁𝗹𝘆 to automate one of the most repetitive parts of robotics development. Instead of manually converting CAD assemblies, configuring joints, generating robot descriptions, and debugging the first setup, the goal is a verified, ready-to-use robotics workspace automatically in 𝗴𝗮𝘇𝗲𝗯𝗼 and 𝗥𝘃𝗶𝘇.

But now I’m at a point where the technical part feels solid. The new challenge is figuring out how to reach the right users for such a 𝘁𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗽𝗿𝗼𝗱𝘂𝗰𝘁.

If you’ve built developer tools or engineering software, how did you get your first 10 to 50 users? What channels actually worked? What wasted effort would you skip if you started again?
