How to launch your SaaS on Reddit without getting banned
To launch a SaaS on Reddit, pick subreddits whose rules allow sharing your work (like r/buildinpublic or r/SideProject), build some genuine comment history first, and post a story, not an ad: what you built, why, and what happened, with a short video and the link in context. Say clearly that you're the maker and reply to every comment.
- Read each subreddit's rules before posting
- Post a founder story with a short video, not an ad
- Disclose that you're the maker
- Reply to every comment for the first hours

Does a Reddit launch actually work for SaaS?
It can, and it costs nothing. We launched MarketFast, our own SaaS, with one post in r/buildinpublic: a 52-second video and an honest title about getting our first paying users from it. The post passed 55K views and brought 200+ users in the first 24 hours, with €0 spent on ads.
It works because Redditors reward honesty and punish anything that looks like marketing. The same post written as an ad would have been removed or ignored.

Which subreddits to post your SaaS in

Every subreddit sets its own rules on self-promotion, and they change. Read the rules in the sidebar of each one before posting. As a starting point:
| Subreddit type | Examples | What works there |
|---|---|---|
| Build-in-public and maker communities | r/buildinpublic, r/SideProject, r/indiehackers | Sharing what you built, with the story and numbers |
| Founder communities | r/SaaS, r/startups, r/Entrepreneur | Lessons and results; many limit promotion to specific threads or days |
| Your buyers' own communities | The subreddit where your users talk about their job | Helping first; product mentions only where the rules allow it |
The subreddits where your buyers hang out convert best and are the strictest. Build comment history there for weeks before you ever mention your product.
How to write a Reddit launch post that doesn't read like an ad
- 01Title: the story, not the product"I got my first paying users from this video" beats "Introducing MarketFast, the #1 tool for...". Lead with what happened.
- 02Open with the problem you livedTwo or three lines on why you built it. Redditors upvote people, not products.
- 03Show it in a short videoNative video plays right in the feed. 30 to 60 seconds, real screens, the pain in the first 3 seconds.
- 04Say you're the makerHiding it is the fastest way to get called out. Being upfront earns trust.
- 05Put the link where it makes senseIn the post or the first comment, depending on the subreddit's rules.
- 06End with a real questionAsk for feedback you actually want. It starts the conversation.
Reddit rules to respect so you don't get banned
- Follow each subreddit's self-promotion rules. When unsure, message the moderators before posting.
- Never ask for upvotes or use other accounts to vote. Reddit treats it as vote manipulation.
- Don't post the same text in many subreddits at once. Adapt the post to each community, or wait.
- Use an account with real history. Brand-new accounts with no karma often get filtered automatically.
- Don't delete and repost if it doesn't take off. Learn from it and try another community later.
What to do after your Reddit post goes live
- 01Stay for the first hoursReply to every comment, including the critical ones. Good answers to tough comments win the thread.
- 02Turn questions into product fixesReddit feedback is blunt and free. Ship the quick fixes and say so in the comments.
- 03Follow up with signupsThank new users personally. Some of your best early customers come from Reddit threads.
- 04Reuse the videoThe same launch video goes out on X and LinkedIn, and later on your homepage.
Frequently asked questions
Can you promote your SaaS on Reddit?
Yes, where the subreddit's rules allow it. Many communities allow sharing your work if you're upfront that you're the maker and contribute beyond your own posts. Always read the rules first.
What is the best subreddit to launch a SaaS?
Build-in-public and maker communities like r/buildinpublic and r/SideProject are the most open to launches. The subreddits where your buyers talk about their work convert best but are stricter.
Why was my Reddit post removed?
Usually because it broke the subreddit's self-promotion rules, the account was too new, or it read like an ad. Check the rules and ask the moderators.
Should I use a video in a Reddit launch post?
Yes. A short native video plays in the feed and shows the product faster than text. Our MarketFast launch on Reddit was a 52-second video.
Do Reddit ads work better than organic posts for a launch?
For a first launch, an organic founder post usually builds more trust. Ads can scale what already works later.
