I got tired of guessing what to build, so I built this
I kept seeing builders (including myself) struggle with the same question:
“What should I build?”
Most of us end up copying something that already exists, or building based on assumptions.
But people are already talking about their problems every day on Reddit.
So I built IdeaFast to turn those conversations into something useful.
You pick the subreddits you care about. IdeaFast finds recurring customer pain, clusters and scores it, and links every pain point back to the original Reddit discussions. You can then turn the strongest problems into startup ideas.
The idea is simple:
Don’t start with an idea. Start with a real problem.
Would love to hear how other indie hackers currently find problems worth solving.
I’m still improving IdeaFast, so I’d genuinely love your feedback. What would you change or add?
I'm curious what made you decide recurring pain is a better starting point than founder intuition.
Did you notice ideas changing once you could trace them back to multiple conversations instead of a single discussion?
Yeah, that was the main reason. Founder intuition can point you in a direction, but recurring pain gives you a stronger signal that the problem isn’t isolated.
And yes, seeing the same pain across multiple conversations often changes the idea. You start building around what keeps coming up, rather than what one person happened to complain about.
Appreciate the context.
The shift from building around a single opinion to recognizing repeated patterns is the interesting part.
Would be good to understand how you're applying that process as you evaluate ideas.
