Hey Product Hunt, Will here, founder of Build Signals 👋 I built Build Signals because choosing what to build often feels like guesswork. Founders usually start with an interesting idea, then search for evidence that supports it. I wanted to reverse that process. Build Signals starts with real market, regulatory, developer and commercial signals. The strongest opportunities become detailed reports covering: • Who the first customer is • Why they would pay • Evidence that the problem is real • The smallest MVP worth building • How to validate it in seven days • Where to find the first ten customers • What could make the idea fail • A Claude Code build pack to start shipping The goal is not to produce more startup ideas. It is to help founders avoid wasting months on the wrong one. I would love your honest feedback: What is the hardest part of choosing what to build next? And what evidence would make you confident enough to commit to an idea?

That's why I built Build Signals.

Instead of generating random startup ideas, Build Signals researches markets the way an analyst would. It looks for real signals like:
