Best subreddits for SaaS founders
The best subreddits for SaaS are r/SaaS for peer founders, r/startups and r/Entrepreneur for reach, and r/microsaas and r/indiehackers for the build-in-public crowd. Your buyers, though, usually live in the niche subreddit for the problem you solve. A bookkeeping tool wins in r/smallbusiness, not r/SaaS.
Most of these communities restrict or ban direct self-promotion. The play that works is answering questions where your product's problem comes up naturally, and only linking when someone asks.
The communities
| Subreddit | Members | How to use it |
|---|---|---|
| r/SaaS | 776k | Peer founders comparing stacks, pricing, and growth tactics. Feedback and launch-story posts do well; drive-by links don't. |
| r/startups | 2.1M | Broad startup audience. Strict self-promo rules. Earn attention with substance, share links only where the rules allow. |
| r/Entrepreneur | 5.3M | The biggest general business room. Great for lessons-learned posts; promotional posts get removed fast. |
| r/smallbusiness | 2.5M | Your buyers if you sell to SMBs. Answer operational questions; the products that help get asked for. |
| r/EntrepreneurRideAlong | 718k | Build-in-public journeys. Documenting your progress is the content. Promotion rides along legitimately. |
| r/microsaas | 208k | Small, focused products and the people building them. Tolerant of founder stories, allergic to funnels. |
| r/indiehackers | 187k | Bootstrapper crowd. Revenue-number honesty is the currency here. |
| r/GrowthHacking | 153k | Tactics and experiments. Share what worked with numbers, not landing pages. |
