You'll find founders sharing actual revenue numbers, growth strategies, and honest takes on what's working in 2026. The community actively downvotes promotional content, so the signal-to-noise ratio stays high.

The Reddit extension of Indie Hackers maintains the same quality standards as the main platform. Solo founders and small teams share bootstrapping strategies, revenue updates, and honest feedback on each other's products. The community celebrates small wins and provides realistic advice for founders building without massive funding.

While you don't need to be in YC to participate, this community revolves around the YC ecosystem. Current founders, alumni, and applicants share experiences about the program, fundraising, and scaling. The discussion quality is consistently high because many participants are vetted founders who've been through YC's rigorous selection process.

The largest dedicated startup community on Reddit covers everything from idea validation to exit strategies. While the size means more noise, active moderation keeps quality discussions visible.
