How to post in the best founder subreddits
Every founder subreddit has its own rules about promotion, and the fastest way to get a launch removed is to treat them all the same. r/startups bans standalone promo, r/SaaS allows one mention every 60 days, r/Entrepreneur makes you comment before you post, and r/smallbusiness only accepts questions. Each guide below covers one community: what it allows, what gets you removed, and a worked example.
These are companion guides to the writing itself. Once you know a subreddit’s rules, use the post generator to draft something in its voice, and the launch checklist to get the account and timing right.
Seven founder subreddits, seven rulebooks
One of the largest founder communities, and one of the strictest on promotion.
A rare subreddit built for sharing your project, where promotion is the point.
An active SaaS community that allows promotion, but on a strict rate limit.
A huge general business community with a hard participation gate and an AI-content ban.
A large, strictly question-and-answer community that tightened its promo rules in 2026.
A small Reddit community, separate from the indiehackers.com website of the same name.
A small, focused community where sharing is welcome only if the post carries real substance.
Draft a post for any of these subreddits
Name the community you are aiming at and the generator shapes your draft to its voice, then flags the removal triggers before you post. Free, no signup.
Title options
Different rules, same underlying principle
Be a participant first
The formal 9:1 ratio is retired, but every one of these communities still expects you to contribute genuinely before you promote. A comment history is what earns the post.
Promote in the right place
Most of these subreddits have a sanctioned spot for promotion, whether a weekly thread or a required flair. Using it is the difference between a share and a removal.
Read the live rules
Subreddits change policies, sometimes with little notice. Each guide reflects the rules as read recently, but confirm against the live rules page before you post.
