Best subreddits for startups and entrepreneurs.
The big founder communities have the largest audiences on Reddit and the tightest promotion rules. Member counts and rules below were read from Reddit on 7 November 2026; most of these communities ban promotion outside a weekly thread, so they work for listening and disclosed answers more than for posting an offer.
The full playbook: Reddit marketing for startups →
Bans promotion, URLs and DM requests; free offers only in the weekly threads. You must comment on other posts before you post.
weak — brand/awareness only
Useful answers under a named person's account. Offers wait for the designated weekly thread.
No promotion of any kind outside stickied threads such as the Monthly Share Your Startup thread. Posts can't tie the discussion to your own project's name or URL.
weak — brand/awareness only
Experience and lessons posts without a project link; the monthly thread for the startup itself.
Question-and-answer only. Promotion goes in the weekly Promote-your-business thread, and since June 2026 promotional-looking product mentions are removed.
moderate
Owners ask in public what to buy and whom to hire. We answer from experience and mention a business only where a reply makes it relevant.
Built for sharing projects and getting feedback. Reddit lists no written rules for it, so read the sidebar and submit text before you post.
weak — brand/awareness only
Real projects shown in the format the submit text asks for, not branded campaigns.
One self-promotion post with the Self Promotion flair, for feedback and critique. Revenue claims need proof.
moderate
Spend the single self-promotion post on a request for critique; contribute elsewhere.
Three general rules about respect and good intent; none sets a promotion limit, so ask the mods before posting anything commercial.
weak — brand/awareness only
First-person founder stories; announcements read out of place.
