Reddit marketing guide
The best subreddits for SaaS founders
If you're building a SaaS, your buyers are already on Reddit — you just have to post where they are, in a way that won't get you removed. Here are the subreddits worth your time and how to choose the right ones for your product.
The core subreddits for SaaS founders
- r/SaaS — founders and operators talking shop. Strictly anti-pitch, but gold for feedback and value-first posts.
- r/startups — broad startup audience; strong for 'lessons learned' and milestone posts.
- r/Entrepreneur — huge reach, more general business audience.
- r/EntrepreneurRideAlong — build-in-public friendly, smaller and more engaged.
- r/IndieHackers / r/SideProject — the most welcoming places to share 'I built this'.
- r/marketing and r/growmybusiness — when your product helps people market or grow.
Don't stop at the obvious ones — go niche
The big subreddits have reach but brutal competition and strict rules. The subreddits that actually convert are usually the niche communities built around the exact problem you solve.
Sell a tool for Notion users? r/Notion. A design tool? r/web_design, r/graphic_design. A dev tool? The subreddit for that language or framework. These smaller communities have higher intent and far better conversion than the giant general subs.
How to pick the right subreddits for your product
Score each candidate on three things: relevance (does the audience have the problem you solve?), size (enough members to matter, but not so big you're invisible), and rules (do they allow any self-promotion at all?).
A 20,000-member subreddit of people with your exact problem beats a 2-million-member general sub almost every time.
How to actually post without getting removed
Read each subreddit's self-promotion rules first — they vary wildly. Build a little karma and comment history before posting. And lead with value: a teardown, a result, a lesson — not a link.

Frequently asked questions
What is the best subreddit to promote a SaaS?
It depends on your product, but the most useful starting points are r/SaaS, r/startups, r/Entrepreneur, r/IndieHackers, and r/SideProject — plus the niche subreddit for your specific audience, which usually converts best.
Can I post my SaaS in r/SaaS?
Only carefully. r/SaaS removes anything that reads like an ad. Share lessons, ask for feedback, or post results — and let your product come up in the comments rather than the title.
How many subreddits should I target?
Start with 5–8 well-matched subreddits rather than blasting dozens. Posting the same thing across many subreddits is a fast way to get flagged as spam.
