PainSignal

What is PainSignal?

PainSignal helps founders find SaaS ideas people already want to pay for. It scans online conversations across Reddit, Hacker News, Dev.to, Stack Overflow, X, YouTube, Bluesky, and the broader web to uncover painful problems, score demand, and estimate revenue. You can paste your own idea too, and it will quickly tell you if it looks worth building or should be dropped. The product also gives you a practical blueprint: what to build, how to build it, the best tech stack, a launch timeline, and even the first people to contact. It is built for people who want to stop guessing and start shipping with evidence.
