# IdeaHunter > IdeaHunter is an evidence-led app idea research database for solo founders, indie hackers, vibe coders, and people building a side business. It turns observable user pain and market momentum into focused research leads with source evidence, buyer context, MVP scope, and a monetization hypothesis to test. IdeaHunter is not a generic AI idea generator. Its records begin with external signals such as community complaints, app reviews, buyer requests, job posts, open-source activity, app-store momentum, and software-business marketplace data. An idea is a research lead, not a guarantee of product-market fit. Primary audience: solo founders, indie hackers, AI-assisted builders, and part-time entrepreneurs. Primary use case: find a narrow app or micro-SaaS idea that one person can validate or ship in roughly one to two weeks.
