The problem is simple: choose the wrong subreddits, and your effort is largely wasted.
This list is not a generic roundup. It’s curated specifically for SaaS founders and developers, evaluated across user quality, activity level, marketing tolerance, and realistic entry strategies — with the goal of helping you turn Reddit into a sustainable acquisition channel.

How SaaS Founders Should Use This List
If you’re new to Reddit marketing, don’t try to cover all 30 subreddits at once.
A more effective approach is:
- Start with r/SaaS, r/SideProject, and r/IndieHackers
- Then move into niche communities closely aligned with your product
- Use large subreddits mainly for brand exposure, not conversion
FAQ
1. How should SaaS founders market on Reddit?
The core rule is simple: value first, product second.
A practical approach:
- Don’t start with marketing. Share your unique insights, experience, and perspective.
- Participate consistently. Mention your product naturally in context and honestly ask for feedback.
- Always lead with content value. Hard advertising almost never works on Reddit.
2. What should I do if my Reddit accounts keep getting banned?
Check in this order:
- Your IP and network environment
- Whether your content feels overly promotional
- Whether you actually followed the subreddit rules
Most bans are execution problems — content that doesn’t align with subreddit rules.
If you don’t want to spend excessive time managing accounts, you can use Leadmore AI’s Safe Posting feature, which can reduce account ban risk by up to 90%.
3. What if my content direction is correct but posts keep getting removed?
Follow this process:
- Carefully re-read the subreddit rules. Most removals still trace back to rule mismatches.
- After ruling out account-level issues, politely message the moderators to ask why the post was removed.
Before contacting mods, it’s best to first eliminate account-related risks.
You can test posting with Leadmore AI’s Safe Posting feature:
- If posts are still removed after using safe posting, the issue is likely content or community rules
- At that point, communicating with the moderators is much more effective
4. Is Reddit suitable for launching a brand-new SaaS product?
Yes — if your goal is honest product feedback, not aggressive promotion.
Reddit works extremely well for:
- Validating real demand
- Collecting early user feedback
- Discovering blind spots in your product
Treat it as a research and conversation platform, not an ad channel.
5. Are larger subreddits always better?
No.
For SaaS founders, user relevance beats subscriber count every time.
A niche subreddit with 20,000 members often delivers better feedback and conversions than a generic community with millions.
Final Thoughts
For SaaS founders, Reddit is a long-term growth channel — not a one-off traffic hack.
Choosing the right subreddits, respecting community rules, and controlling execution risk matters far more than posting volume.
