Where Founders Go to Find Startup Ideas

This list curates concrete places founders and indie hackers go in 2025 to spot and validate startup ideas across web apps, podcasts, newsletters, and YouTube channels. It focuses on global, English-language sources that surface real launches, market trends, and problem discovery, spanning free options and paid communities under roughly $400/year. Items emphasize actionable idea flow for SaaS, Micro-SaaS, consumer apps, and B2B tools, avoiding generic directories and including platforms with active communities or vetted research. Typical use cases include scanning daily launches for whitespace, exploring underserved niches, validating demand through trend curves, and hearing operators describe opportunity selection. The scope stays within idea-sourcing media and tools rather than courses or accelerators, includes both bootstrapper- and VC-friendly venues, and prioritizes canonical links. It’s intended for early-stage founders, solopreneurs, and product teams seeking repeatable idea pipelines.
