Top subreddits to grow your SaaS: 20 communities worth joining (with weekly visitors)

Communities are slow. They compound.

List of SaaS subreddits for founders (weekly visitors)

If you’re trying to grow a SaaS without burning cash on ads, Reddit can be a real channel — but only if you treat it like communities, not distribution. The win is not ‘drop link → traffic’. The win is: learn the language, become a recognizable contributor, and share only when it is genuinely useful.

Below is a curated list of 20 subreddits where SaaS founders can hang out, get feedback, find early users, and (carefully) share launches. The list is sorted by weekly visitors so you can prioritize.

Before you post: 5 rules that keep you from getting banned

  • Read the subreddit rules and pinned posts first (seriously).
  • Don’t lead with a link. Lead with context and a real question.
  • Share outcomes and numbers, not hype (people reward honesty).
  • Answer other people’s posts before you self-post.
  • If you do share a link: make it optional (‘If useful, link is…’) and be ready to answer comments fast.

A simple posting plan (so it turns into growth)

  • Week 1: lurk + comment (10 helpful comments; no links).
  • Week 2: one value post (template/checklist/results) + answer every comment.
  • Week 3: one feedback post (roast my landing page / positioning) and actually implement 1–2 suggestions.
  • Week 4: a quiet CTA (only if the thread is clearly asking for a tool).
