Reddit marketing guide
The best subreddits for startups
Whether you're looking for early users, feedback, or your first wave of traffic, Reddit has a community for it. Here are the subreddits every startup founder should know — and how to use each one.
Communities for founders and operators
- r/startups — broad startup discussion; great for lessons-learned and milestone posts.
- r/Entrepreneur — massive reach across all kinds of business builders.
- r/SaaS — sharp, software-focused audience (strictly anti-pitch).
- r/EntrepreneurRideAlong — build-in-public friendly and highly engaged.
Communities to launch and get feedback
- r/SideProject — the most welcoming place to share 'I built this.'
- r/IndieHackers — bootstrappers and solo founders sharing real numbers.
- r/roastmystartup and r/AlphaandBetausers — direct feedback and early testers.
These smaller, builder-friendly subs are where launch posts actually get a warm reception.
Don't forget your niche communities
Your highest-converting subreddit is usually the one built around your customer, not around 'startups.' If you sell to designers, marketers, developers, or a specific industry, those subreddits have the buyers — the general startup subs mostly have other founders.
How to post without getting removed
Every subreddit has different self-promotion rules — read them first. Build a little karma and history before posting. And always lead with value: a story, a result, or genuine feedback request, not a link.
