Best Subreddits for SaaS Founders 2025: OGTool's Complete Guide
Founder of OGTool, Ex-Stanford, Bootstrapped to 500k+ organically
Last year, I helped a customer make $280k from Reddit alone. She went from 3% to 70% share of voice among competitors and now ranks #1 on ChatGPT for "best ADHD coaching companies."
The secret wasn't posting random content or spamming links. It was being active in the RIGHT subreddits with the RIGHT approach.
Here's what I learned after analyzing thousands of successful Reddit comments and helping dozens of SaaS founders turn Reddit conversations into customers.
Why Most SaaS Founders Get Reddit Wrong
In SaaS, Reddit is still considered, by most marketers, as a niche and risky channel. With 95% of organizations having implemented SaaS solutions and SaaS apps comprising 70% of corporate apps, with projections indicating an increase to 85% by 2025, there's massive opportunity for founders who get it right.
The problem? They're either:
- Posting promotional content that gets instantly banned
- Joining the wrong communities where their customers don't hang out
- Using corporate language instead of sounding like a real person
Reddit has emerged as a powerhouse platform for B2B decision-making, with 75% of surveyed B2B users consulting Reddit for future purchase decisions. Communities within subreddits like r/SaaS and r/Entrepreneur are filled with individuals who are interested in the latest trends and tools.
Manual Reddit marketing is inefficient and time-consuming - here's how smart founders are automating their approach
The 10 Must-Join Subreddits for SaaS Founders
1. r/SaaS (386k members)
r/SaaS is a closely moderated Subreddit forum with over 100k users and high engagement. The community is popular because SaaS founders talk honestly and openly about their experiences with SaaS – the highs, the lows, and everything in between – and help each other with technical troubleshooting.
Why it works: It's one of the few subreddits where self-promotion is allowed, as long as it's thoughtful and non-salesy. A standout feature is the Weekly Feedback Thread, where members are encouraged to share their products or MVPs to get honest feedback.
What to post: Share your startup journey, ask for feedback on features, discuss pricing strategies.

2. r/Entrepreneur (2.8M members)
r/Entrepreneur is by far the largest and one of the oldest startup subreddits in our list, and for good reason. It's very active, engagement is high, and the mods work hard on it. There's 'NooB Monday', a stickied thread for newcomers to post to, and a weekly Ask Me Anything (AMA) with successful entrepreneurs.
Why it works: Massive audience of business-minded people looking for solutions.
What to post: Business lessons learned, growth stories, industry insights.
3. r/IndieHackers (200k+ members)
r/indiehackers is a community for founders, builders, and solopreneurs sharing the ups and downs of creating and growing products independently. From zero-to-one product launches to $10K MRR milestones, this subreddit is packed with real stories, tactical advice, and honest feedback. If you're building something solo or with a small team, especially a SaaS product, this is one of the best places to learn and share without being overly polished.
Why it works: Perfect for bootstrapped SaaS founders. Community values transparency over polish.
What to post: Revenue milestones, building in public updates, technical challenges.
4. r/Startups (1.5M members)
r/Startups: A community for startup founders, including SaaS founders, to discuss the challenges and rewards of building a business from scratch. Topics include fundraising, marketing, scaling, and product development. It's ideal for those looking to grow their SaaS startup.
Why it works: Broad startup audience with many potential customers and partners.

What to post: No-code tutorials, automation workflows, tool reviews.
How to Actually Use These Subreddits (Without Getting Banned)
Based on my experience helping customers generate hundreds of thousands in revenue from Reddit, here's what actually works:
The Right Way to Comment
1. Stuff Your Comment with 3-5 Tips Share genuinely helpful advice. Your product can be one of the tips, but not the only one.
2. Disclaim You're Working on It Focus 90% on helping, then add: "Full disclosure: I'm the founder of [Company] which also helps with this."
3. Share What Worked for You Personally Tell your actual story and what specific insights helped you.
What NOT to Do
- Generic responses that could apply to any post
- Acting like a third party when you're clearly affiliated
- Making 100+ comments per day (start with 5-10)
- Using corporate language instead of personal voice
How OGTool Finds the Perfect Subreddits for You
Here's the thing: these 10 subreddits are just the starting point. The real magic happens when you find the specific communities where YOUR customers hang out.
OGTool automatically:
- Monitors 100,000+ subreddits for your keywords
- Identifies high-value discussions in real-time
- Filters out low-quality opportunities
- Finds niche communities you'd never discover manually
For example: If you're building a project management tool, OGTool might find active discussions in r/consulting, r/freelancers, r/remotework, or even r/ADHD where people are struggling with organization.
OGTool's keyword management dashboard makes it easy to track and manage your subreddit monitoring strategy
The Smart Monitoring System
Once OGTool finds relevant conversations, it:
- Analyzes the context to understand what help people need
- Generates authentic responses in your voice
- Suggests when and how to mention your product naturally
- Tracks which types of comments get the best engagement
The Results Speak for Themselves
My biggest customer now makes about 100 comments per month across these subreddits. Here's what happened:
- $280k in direct sales from Reddit in one year
- 70% share of voice among competitors (up from 3%)
- #1 ranking on ChatGPT for her industry keywords
- Front page Google results when people search "[industry] reddit"
The comments she made months ago are still working for her today, bringing in customers while she sleeps.

Why This Works Better Than Traditional Marketing
Google's partnership with Reddit now pushes community discussions to the top of search results. Reddit's U.S. advertising revenues are projected to climb 30.9% year-over-year in 2025, reaching $1.14 billion. At the same time, SaaS users are voicing raw pain points on subreddits where peers—not polished ads—shape buying decisions.
Traditional ads stop working when you stop paying. Reddit comments compound over time. A helpful comment from 6 months ago can still generate leads today.
With average cost-per-click rates around $0.75 and CPM starting at just $3.20, Reddit offers significantly lower acquisition costs than platforms like LinkedIn, which typically charges $15-25 CPM for B2B targeting.
On Reddit, credibility is the growth lever. Every upvote is a public endorsement, every thank-you a micro-testimonial. For SaaS brands, this means the fastest path to adoption isn't shouting louder—it's solving problems in the moment they're raised.
FAQ
How do I avoid getting banned on Reddit?
Start slow with 1-2 comments per day on a new account. Use your real founder persona, not a fake user account. Follow each subreddit's rules and focus on being helpful first, promotional second.
Should I create a company account or personal account?
Always use a personal founder account. People trust individuals more than companies. The trick to reddit is to really, truly provide value. If you do that, people will forgive the occasional (tasteful) plug.
How long does it take to see results?
Technology companies typically see initial engagement within 60-90 days of authentic community participation, with measurable lead generation appearing within 4-6 months. Reddit's longer attribution windows require patience, but the lead quality often significantly exceeds other B2B channels.
Can OGTool automate my Reddit comments?
No, and you shouldn't want it to. Reddit can detect automated comments and will ban you. OGTool finds the conversations and generates responses, but you copy and paste them manually. This approach has kept our biggest customer's account active for over a year with minimal bans.
Is Reddit marketing scalable?
Absolutely. Once you have a system, you can hand it off to a team member. They spend 30 minutes daily finding posts with OGTool and making comments in your voice. My customer now has her executive assistant handle this completely.
How is OGTool different from other Reddit tools?
OGTool is the #1 tool built specifically for SaaS founders to turn Reddit conversations into customers. We don't just find keywords – we understand context, generate authentic responses, and help you build relationships that convert. Plus, we integrate with your knowledge base so every response sounds like it came from you personally.
Reddit isn't just a social platform anymore. It's where your customers go for honest advice, and where buying decisions get made. The SaaS founders who figure this out first will have a massive advantage.
