r/startups_promotion
Startup founders and entrepreneurs
Why join
r/startups_promotion is the most direct fit in this set because the community exists for startup promotion, but its public rules still call out self-promotion, spam, relevance, and tone.
What to post
- Share a concise launch post with the startup name, who it helps, what changed, and a real discussion prompt.
- Ask for feedback on positioning or messaging after explaining the audience and stage.
What to avoid
Avoid repeated promotion, vague pitches, or posts that ignore its spam and relevance rules.

- Rule to remember
- This is a sub for startup products, launches, and how tos. Posts can promote but must be relevant. Posts should be related to startups.
2
r/PlugYourProduct
Marketing and growth communities
Why join
r/PlugYourProduct is built around product plugging, so it belongs near the top when a founder wants a promotion-tolerant room.
What to post
- Post the product clearly with the user, use case, and why it is different.
- Offer a useful founder note such as the problem, launch lesson, or early feedback request.
What to avoid
Do not treat the subreddit as permission to spam; follow the visible rules on relevance and post quality.

- Rule to remember
- This is a place to safely promote products. It's not a place to air grievances or critiques.
3
r/LaunchMyStartup
SaaS founders and operators
Why join
r/LaunchMyStartup is a focused launch community from the Notion source list and the fetched rules page exposed a public posting rule.
What to post
- Share a launch with a clear description, target user, stage, and what kind of feedback you want.
- Turn a launch update into a small story about what was built and what you learned.
What to avoid
Avoid empty link drops and any post that skips the visible public rule before publishing.
- Members
- 2,000
- Verified
- 2026-07-09
- Rule to remember
- All launch posts must include at least one image or video showcasing your product/project (screenshots, demos, logos, etc.) along with your text description. Posts without visual content will be removed. This helps other members better understand what you've built and increases engagement with your launch.
4
r/roastmystartup
Product feedback and launch validation
Why join
r/roastmystartup is a better fit when promotion is framed as critique and the founder is ready for direct feedback.
What to post
- Ask the community to critique the landing page, positioning, pricing, or ICP.
- Share what you think is weak and ask for specific feedback, not applause.
What to avoid
Avoid defensive replies, hidden sales funnels, or posts that are really ads pretending to ask for critique.
- Members
- 5,000
- Verified
- 2026-07-09
- Rule to remember
- Unfortunately we experience a ridiculous amount of spam that all have one thing in common - ProductHunt links and.......now Vercel links. Any post with a producthunt or vercel link will be removed. If you don't believe in your startup enough to buy a domain its not worth our time to roast.
5
r/ProductHunters
SaaS founders and operators
Why join
r/ProductHunters can fit a launch when the post connects to discovery, Product Hunt-style feedback, or early adopter discussion.
What to post
- Share the launch angle and ask what would make early adopters care.
- Ask for feedback on positioning before or after a Product Hunt-style launch.
What to avoid
Avoid vote requests, low-context announcements, and link-only promotion.
- Members

- 2026-07-09
- Rule to remember
- Be excellent to each other.
6
r/TestMyApp
Product feedback and launch validation
Why join
r/TestMyApp is useful when promotion is framed as testing and the founder wants feedback on a working app.
What to post
- Ask for testing help with the app, user, device or workflow, and the exact feedback you need.
- Share what changed after previous feedback and what you want testers to inspect next.
What to avoid
Avoid treating a testing community as a generic launch channel or signup funnel.
- Members
- 6,000
- Verified
- 2026-07-09
- Rule to remember
- This has been added to the subreddit rules because it seems it needs to be defined. Advertising services in the comments of every post in the sub is spam.
7
r/GrowthHacking
Marketing and growth communities
Why join
r/GrowthHacking is not a launch board, but it can fit startup promotion when the post is really about an experiment, tactic, or growth lesson.
What to post
- Write a growth experiment teardown with hypothesis, channel, execution, result, and lesson.
- Ask for feedback on a specific acquisition tactic without pushing a tool signup.
What to avoid
Avoid gated lead magnets, SaaS tool pitches without permission, and beta-test collection posts.
- Members

- Rule to remember
- Please don't block content behind a paywall or an opt-in.
8
r/SaaS
SaaS founders and operators
Why join
r/SaaS can support startup visibility only when the post teaches SaaS operators something about pricing, onboarding, retention, positioning, or traction.
What to post
- Share a SaaS lesson with numbers, stage, and the decision other founders can learn from.
- Ask for help on one SaaS operating problem after showing what you already tried.
What to avoid
Avoid vendor spam, product launch spam, and posts whose only job is to drive signups.
- Members
- 95,000
- Verified
- 2026-07-09
- Rule to remember
- Follow the Reddit site-wide rules and please treat others with respect, stay on-topic, and avoid non-productive self-promotion.
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.
