About ideaFast
IdeaFast is a customer research platform that helps founders and builders find real problems worth solving from Reddit conversations. Instead of spending hours scrolling through communities or guessing what people want, IdeaFast finds recurring customer pain, groups similar problems together, scores them based on frequency and intent, and shows the real discussions behind every insight.
You can choose the communities and timeframe you want to research, explore scored pain points, read the original conversations, and turn promising problems into startup ideas. You can also validate an existing idea against real Reddit discussions before spending months building it.
IdeaFast helps you start with real customer pain, understand what people actually need, and build products around real demand instead of assumptions.
