Best Fit

Use this list when the goal is explicit startup visibility, not general founder education. Start with promotion-tolerant communities, then move into critique or lesson-based communities when the post gives the room something useful.

What To Post

A good startup promotion post is still a Reddit post. Lead with the user, problem, stage, what changed, and the exact feedback or discussion you want. When the community is not explicitly promotional, turn the launch into a lesson, teardown, or question.

What To Avoid

Avoid repeated copy-paste launches, vote requests, DM funnels, beta signup traps, and posts where the only value is a link. If the subreddit guide warns about spam, self-promotion, surveys, or low-effort posts, assume moderators will read the launch through that lens.

Rule Note

Every subreddit in this list links to an individual Rankhog guide with fetched Reddit rules, source URLs, stats, and a last-verified date. Communities from the Notion source that did not expose public rule items were held back instead of being guessed into the list.

Rankhog Notes

For a safer campaign, write one Reddit-native angle per subreddit. The same startup can be a launch in one room, a critique request in another, and a growth experiment in a third.

Common questions

What are the best subreddits to promote a startup?

Start with promotion-tolerant communities such as r/startups_promotion, r/PlugYourProduct, and r/LaunchMyStartup, then use feedback-first rooms such as r/roastmystartup, r/ProductHunters, and r/TestMyApp when the post asks for useful critique.

Can I post the same startup launch in every subreddit?

No. Each subreddit has its own public rules and audience context. Rewrite the post around the reason that specific community should care.

What should a startup promotion post include?

Include the target user, problem, what changed, proof or context, and one useful question. The post should still create value if the reader never clicks your link.

Which startup-promotion subreddits did Rankhog hold back?

Rankhog did not publish new pages when the fetched public rules page exposed no rule items or Chrome could not verify the community context. Those communities stay out of this list until rules can be verified.
