Frequently Asked Questions

Which subreddits allow startup promotion?

r/SideProject, r/IMadeThis, and r/alphaandbetausers are built for sharing. r/startups and r/SaaS allow it only in designated threads.

Where can I find beta users for my SaaS?

r/alphaandbetausers is designed for recruiting early testers.

How do I promote my SaaS on Reddit without getting banned?

Read each subreddit's rules, contribute genuinely before posting links, and use designated promotion threads. See our guide to marketing on Reddit.

Should a SaaS company own a subreddit?

Often, yes. A subreddit for your category (not just your brand) gives you a distribution channel and search visibility. You can claim abandoned ones through r/redditrequest if all human mods have been inactive 60+ days. DeadSubs finds them.
