Where Can I Promote My Startup on Reddit? 40+ Subreddits, Sorted by How Much Promotion They Allow (2026)
The short answer
The best places to promote a startup on Reddit fall into four groups: subreddits built for sharing projects (like r/SideProject and r/IMadeThis), big communities that allow promotion only in pinned threads or on set days (like r/startups, r/SaaS and r/webdev), feedback-first communities (like r/roastmystartup), and the niche subreddits where your buyers ask for recommendations but promotion is banned. Launch posts belong in the first two groups. Buyers are mostly in the last group, where only genuinely helpful, rule-following answers work.
Key takeaways
- Launch-friendly subreddits are great for feedback and early users, but they are full of other founders, not necessarily your buyers.
- Many large subreddits ban self-promotion except in a pinned weekly or monthly thread, or on a set day like Showoff Saturday. Always check the pinned posts and sidebar.
- Your real customers are usually in niche communities that ban promotion. There, you earn mentions by answering questions well, not by posting launches.
- Spend two weeks participating before you launch, post with a clear problem, a demo and honest pricing, and reply to every comment in the first few hours.
- Rules change often. Treat this list as a starting point and read each community's rules on the day you post.
Before the list: the one thing most founders get wrong
Most "best subreddits to promote your startup" lists send you to the same ten founder communities. Those are useful for feedback, beta users and a small launch-day bump. They are rarely where your customers are.
A project management tool for architects will find more buyers in an architecture subreddit than in r/startups. A Shopify app will find more buyers where store owners ask for help than where founders share launches. So this guide sorts subreddits into four groups by how much promotion they allow, and tells you what kind of post works in each.
Group 1: Subreddits built for sharing what you made
These communities exist for showing projects. Promotion is the point, but quality, format and genuine engagement still matter. Expect other makers, not big budgets.
| Subreddit | Best for | What works |
|---|---|---|
| r/SideProject | Software and web projects | Short story of why you built it, a demo, and a specific question |
| r/IMadeThis | Anything you built or made | Visual posts and short demos |
| r/indiehackers | Bootstrapped founders | Revenue, lessons and build-in-public updates |
| r/microsaas | Small SaaS products | Niche tools with clear pricing |
| r/EntrepreneurRideAlong | Founders documenting a journey | Progress posts and honest numbers |
| r/buildinpublic | Public building updates | Weekly updates with metrics |
| r/coolgithubprojects | Open-source repos | Link to the repo with a clear README |
| r/opensource | Open-source software | Truly open-source projects only |
| r/chrome_extensions | Browser extensions | Clear use case and screenshots |
| r/nocode | No-code builds | How you built it, with tools named |
| r/ProductHunters | Product Hunt launches | Launch-day posts and feedback swaps |
| r/indiegames and r/IndieDev | Indie games | Gameplay clips and devlogs |
| r/SmallYTChannel | Small YouTube channels | Following its posting format |
| r/selfpromotion and r/shamelessplug | Anything | Low engagement, low value. Fine, but do not expect much |
Group 2: Big communities with pinned promo threads or promo days
These communities have large audiences and strict rules. Self-promotion is usually banned in regular posts and allowed only in a recurring pinned thread or on a specific day. Post outside that slot and your post will likely be removed.
| Subreddit | How promotion works (check the pins) | What works |
|---|---|---|
| r/startups | Recurring pinned thread for sharing your startup; regular posts must be discussion | Lessons, questions and data in regular posts, your link only in the thread |
| r/SaaS | Weekly feedback or show-and-tell thread, typically on Saturday | Detailed questions about pricing, churn and growth |
| r/smallbusiness | Designated weekly promotion thread | Practical small business advice |
| r/Entrepreneur | Very strict; promotion only where pinned threads allow it | Stories and lessons with real numbers |
| r/webdev | Showoff Saturday for your own projects | Technical write-ups on other days |
| r/javascript | Showoff Saturday | Open-source tools and libraries |
| r/gamedev | Screenshot Saturday and other recurring threads | Development lessons, postmortems |
| r/iOSProgramming | App Saturday | Technical posts on other days |
| r/EtsySellers | Designated weekly threads | Seller-to-seller advice |
| r/NewTubers | Promotion only in designated threads | Channel feedback in the right thread |
| r/growmybusiness | Ask for feedback using the required post tags | Questions rather than pitches |
| r/selfhosted | Project posts allowed under community rules on flair and project quality | Self-hostable, well-documented tools |
| r/macapps, r/iosapps, r/androidapps | Developer posts allowed under each community's disclosure and frequency rules | Clear "I'm the developer" disclosure, honest pricing |
Group 3: Feedback-first communities
Great before and right after launch. You get honest, sometimes harsh feedback and a few early users.
| Subreddit | Best for |
|---|---|
| r/roastmystartup | Brutal feedback on your idea, site or pitch |
| r/alphaandbetausers | Recruiting beta testers |
| r/design_critiques | Feedback on design and UX, not the business model |
| r/Roastmylandingpage | Landing page feedback |
| r/AppIdeas | Validating an idea before building |
| r/startup_ideas | Early idea discussion |
Group 4: Help-only communities where your buyers are
These subreddits usually ban self-promotion outright. They are also where people ask "what tool should I use for this?" A launch post here will be removed. A genuinely helpful answer, with your affiliation disclosed and only where the rules allow mentioning products, can be the most valuable Reddit content you ever write.
| Subreddit | Who is there |
|---|---|
| r/marketing and r/digital_marketing | Marketers choosing tools and agencies |
| r/SEO and r/bigseo | SEO practitioners |
| r/ecommerce and r/shopify | Store owners |
| r/sysadmin and r/devops | IT and infrastructure buyers |
| r/cybersecurity | Security teams (very strict) |
| r/ProductManagement | Product managers |
| r/sales | Sales teams and leaders |
| r/freelance | Freelancers choosing tools |
| r/productivity | People choosing apps and systems |
| r/BuyItForLife | Durable product recommendations |
| Your industry's subreddit | Your actual customers |
That is 40+ communities. To find more in your niche, look at the "related communities" in each sidebar, search Reddit for your category plus "recommend", and use a free tool like our Subreddit Finder.
How to write a launch post that does not get removed
A few details that make a big difference:
- Title: say what it does and who it is for. Skip "revolutionary", "game-changer" and emoji walls.
- Lead with the problem. People upvote stories they recognize, not feature lists.
- Show it. A 20-second GIF beats three paragraphs.
- Be upfront about pricing and limits. Hidden pricing is one of the fastest ways to lose a thread.
- Disclose. "I'm the founder" in the first lines.
- Ask one real question. It invites comments, and comments carry the post.
- Stay for the first 2-3 hours. Reply to everyone, especially critics. Never delete critical comments.
A simple two-week launch plan
Mistakes that get startups banned
- Posting the same launch in 10 subreddits on the same day. It looks like spam and often triggers Reddit's spam filters across communities.
- Asking friends or a Discord to upvote. That is vote manipulation, against Reddit's rules, and can get the post removed and accounts suspended.
- Using a brand-new account. Many communities filter new or low-karma accounts automatically. Build history first. See how to get Reddit karma.
- Multiple accounts or fake "customers". Sockpuppets get spotted, and the backlash is public.
- Unsolicited DMs to commenters. Many communities ban it, and users report it.
- Ignoring the new AI moderation. Reddit's Rules Hub reads posts against the intent of rules, so disguised pitches get caught more often. More in Reddit Rules Hub explained.
Beyond launch day: where Reddit really pays off
A launch post gives you a spike. The long-term value of Reddit is in the threads where buyers ask "what should I use for X?", because those threads rank on Google for months and get cited by AI assistants like ChatGPT and Perplexity. Being mentioned there, honestly and in line with the rules, keeps sending you customers long after launch day. We covered this in how to get recommended by ChatGPT.
Your options for the long game
- Founder-led participation. The most authentic option. It takes 20 to 30 minutes a day, every day.
- Monitoring tools. Alerts for your keywords so you can reply quickly. See the best Reddit monitoring tools.
- Reddit Ads. Labeled, rule-proof reach for launch weeks. Compare costs in our Reddit Ads guide.
- An agency. Hands-off, but usually a monthly retainer.
- ReddBounty Campaigns. Real people mentioning you in buyer threads, with rules checked first. Details below.
How ReddBounty helps after the launch
Post your launch yourself. Founders answering questions is what makes launch threads work. ReddBounty helps with the part that comes after:
- Find buyer threads. Monitoring surfaces threads where people ask for tools like yours, including threads ranking on Google, so you can reply yourself with a Scout AI draft.
- Get mentioned by real people. With a Campaign, real Creators with established Reddit accounts mention your brand in relevant threads, in their own words, under our disclosure policy.
- Rules first. Scout AI checks each Task against the subreddit's rules and flags removal risk before anything goes live. Communities that ban promotion are skipped.
- Pay only for what is live. Your Campaign balance is only used when a post is live and approved, with proof. If a post is removed early, the Task is relisted or refunded.
Frequently asked questions
Which subreddits allow self-promotion?
Communities built for sharing projects, such as r/SideProject, r/IMadeThis, r/alphaandbetausers, r/roastmystartup and r/indiehackers, are the most open. Many larger subreddits, such as r/startups, r/SaaS, r/smallbusiness and r/webdev, allow promotion only in a pinned thread or on a specific day. Rules change, so check each sidebar before posting.
What is the best subreddit to launch a startup?
r/SideProject is the most common first stop for software products, with r/IMadeThis and r/alphaandbetausers for early users and feedback. For your real buyers, look for the niche subreddit where your target customers already ask questions, even if it bans launch posts.
How do I promote on Reddit without getting banned?
Read the rules, participate for a couple of weeks before you post, keep your own promotion a small share of your activity, disclose your affiliation, never ask friends to upvote, never use multiple accounts, and do not post the same launch in many subreddits at once.
Do I need karma to post in startup subreddits?
Often yes. Many communities filter posts from new accounts or accounts with low karma, and the exact thresholds are usually not published. Build some history by commenting helpfully first. Our guide to getting Reddit karma explains how to do it without shortcuts.
When is the best time to post a launch on Reddit?
Post when your audience is awake and active, and when you can stay online for the next two to three hours to reply. For US-heavy communities, weekday mornings Eastern time are a common choice. If a subreddit has a promo day, use that day.
Can ReddBounty post my launch for me?
ReddBounty is built for the other half of Reddit: getting your brand mentioned by real people in the threads where buyers ask for recommendations, in communities whose rules allow it. You should post your own launch from your own account so you can answer questions as the founder.

Reddit Marketing for Agencies: How to Add Reddit and AI Visibility to Your Services in 2026
Clients are asking agencies for Reddit because it is one of the most-cited sources in AI answers and ranks on Google for buying searches. A sound agency offer has five layers: an audit of Reddit and AI visibility, ongoing monitoring, disclosed participation in relevant threads, amplification through AMAs and Reddit Ads, and monthly reporting. Typical B2B retainers run about $3,000 to $12,500 a month. The biggest risk is compliance: under the FTC's Endorsement Guides, agencies can be liable for facilitating misleading endorsements, so disclosure and real accounts are non-negotiable.
Removed, Filtered or Shadowbanned? A Flowchart to Diagnose Any Missing Reddit Post (2026)
A missing Reddit post usually falls into one of four buckets: removed by a subreddit's moderators or their automation (AutoMod, Contributor Quality Score, Rules Hub), caught by Reddit's sitewide spam filters, restricted at the account level (shadowban or suspension), or simply buried. The fastest diagnosis is to check the post logged out, check your inbox and post insights, and test whether the problem happens in one subreddit or everywhere. Each bucket has a different fix, from a polite modmail to a formal appeal.

When locals need a dentist, a mechanic or a good brunch spot, many ask their city's subreddit, and those threads often rank on Google for 'best X in [city]' and get quoted in AI answers. Most city subreddits ban self-promotion outside designated threads, so local businesses win on Reddit by being genuinely helpful locals, responding well when mentioned, using the community's promo threads, encouraging real customers to share honest experiences, and using Reddit Ads' location targeting for openings and events.
