Best Startup Subreddits in 2025

Startups fail often. Most don't make it past year two. Reddit's startup communities help you avoid being a statistic. You might also be interested in our comprehensive guides for best entrepreneurs subreddits, best sales subreddits, best business subreddits.

r/startups (1.9M members) and r/Entrepreneur (4.9M) are the giants. Funding discussions, product-market fit struggles, pivots, success stories, failures. r/EntrepreneurRideAlong (612K) gives you transparent case studies with actual revenue numbers. Like: I'm successful posts but here's exactly what I did and what it cost. r/ycombinator (145K) connects YC alumni and applicants. For validation, r/Startup_Ideas (183K) and r/startupideas (14.8K) test concepts before you waste time building.

What separates these from startup blogs? Real operators, not observers. People actually building companies, burning through runway, finding customers, hiring teams. They share cap tables, term sheets, mistakes that cost them. The honest discussions about failure teach you more than success stories ever could.
