r/ycombinator: rules, promo tolerance & best time to post

strict — no promo (3/10) · tone: Direct, career-focused, and pragmatic—people ask blunt questions about YC strategy, founder conflicts, and startup viability without much small talk.

Can you promote in r/ycombinator?

Strict: this community removes promotional content on sight. Contribute value only; pitching here risks removal and a subreddit ban.

r/ycombinator is a tightly focused community for aspiring and active YC founders and employees seeking peer wisdom on tough decisions—cofounder fit, idea validation, career timing, and YC mechanics. Mods enforce quality with megathreads to reduce repetitive posts, and the community upvotes experienced founders sharing hard-won insights over generic startup advice. Transparency about struggles and authentic questions are valued; sales pitches and hype are not.

• DO ask for founder experiences and tactical advice—the community rewards storytelling and real-world data
• DO frame questions around career or founder dilemmas; self-reflection resonates
• DO reference YC-specific programs, deadlines, and resources
• DO avoid obvious self-promotion or product pitches—this is a career/founder community, not a marketplace
• DON'T post spam or low-effort recruitment posts
• DON'T ask questions already answered in pinned YC Resources threads without showing effort
• DON'T position yourself as a guru offering unsolicited advice without founder credibility
