The 40 Best Subreddits for SaaS Founders to Find Customers
Grouped by what they're actually good for, with honest notes on promo policy so you don't waste your first post.
Every list like this eventually goes stale - subscriber counts grow, moderator teams change, promo policies get rewritten. Treat this as a starting map, not gospel, and always check a subreddit's current rules (sidebar or wiki) before your first post there. What doesn't go stale is the grouping logic: which communities are worth your time depends entirely on what you're trying to get out of Reddit, not just how big the subreddit is.
Founder and startup communities
Best for peer feedback, build-in-public momentum, and early adopters who expect to see products being built in real time.
| Subreddit | Best for | Promo policy - verify before posting |
|---|---|---|
| r/SaaS | Peer feedback from other SaaS founders, tool recommendations | Self-promo tolerated with context, not as a bare pitch |
| r/Entrepreneur | Broad startup audience, high traffic | Restricted - mostly funneled into weekly self-promo threads |
| r/startups | Advice-first culture, fundraising and early-stage discussion | Discourages direct promotion; case-study framing works better |
| r/EntrepreneurRideAlong | Build-in-public progress updates | Explicitly welcomes founder journey posts |
| r/SideProject | Launching and getting first users for a new product | Built for exactly this - showcase posts are the norm |
| r/microsaas | Small, focused SaaS products and bootstrapped founders | Community built around sharing what you're building |
| r/indiehackers | Bootstrapped founder discussion, revenue transparency | Build-in-public culture; avoid pure ads |
| r/roastmystartup | Blunt, honest feedback on your pitch or landing page | You're explicitly asking for critique - self-promo framing expected |
| r/AlphaandBetaUsers | Recruiting beta testers directly | Built for this exact purpose - follow the post template |
| r/growmybusiness | General small-business growth advice | Advice-first; light self-promo acceptable in context |
Marketing and growth
Best for case-study-style content and reaching other marketers who might use or recommend your tool - less about direct end-user acquisition, more about credibility and referral.
| Subreddit | Best for | Promo policy - verify before posting |
|---|---|---|
| r/marketing | Case studies with real numbers, marketing strategy discussion | Tolerates product mentions inside genuine case studies |
| r/DigitalMarketing | Tactics discussion, channel-specific advice | Discourages direct pitches; educational content preferred |
| r/growthhacking | Growth-loop and acquisition tactics | Product mentions tolerated when tied to a specific tactic |
| r/SEO | SEO-specific tooling and strategy discussion | Strict on self-promo; contribute genuinely first |
| r/PPC | Paid acquisition tooling and strategy | Similar to r/SEO - value-first culture |
| r/content_marketing | Content strategy and tooling | Case-study framing over direct pitches |
| r/Emailmarketing | Email tooling and lifecycle marketing | Tolerant of tool mentions in answers, not standalone posts |
| r/Affiliatemarketing | Affiliate/referral-driven growth tactics | Active self-promo threads exist; check pinned posts |
| r/analytics | Product analytics and measurement tooling | Technical discussion first, tool mentions in context |
| r/CustomerSuccess | Retention and onboarding tooling | Professional-advice culture; light promo in relevant answers |
Technical and developer-adjacent
Highest bar for genuine contribution, and the least tolerant of anything that reads as promotional - but also where the most technically credible, highest-intent audience lives if your product is developer-facing.
| Subreddit | Best for | Promo policy - verify before posting |
|---|---|---|
| r/webdev | Developer tools and technical SaaS products | Strict - value-first, self-promo threads are separate and limited |
| r/programming | Broad developer audience | Very strict on self-promotion; mostly technical discussion only |
| r/SaaSy | Niche SaaS-builder discussion | Smaller community; check current rules before posting |
| r/reactjs | Frontend/dev-tooling products | Technical value expected before any product mention |
| r/node | Backend/infra tooling | Same - technical contribution first |
| r/devops | Infra, monitoring, and ops tooling | Practitioner-first culture, light tolerance for tool mentions in answers |
| r/machinelearning | AI/ML tooling - high bar for technical credibility | Very strict; academic/technical tone required, self-promo mostly disallowed outside designated threads |
| r/artificial | Broader AI product discussion | More tolerant than r/MachineLearning, still value-first |
| r/UXDesign | Design and product tooling | Case-study and portfolio framing works better than direct pitches |
| r/ProductManagement | PM tooling and process discussion | Professional-advice culture, product mentions in context tolerated |
Vertical and operational
Best if your ICP is defined by function (HR, accounting, e-commerce operations) rather than by "founder" or "marketer" as a role.
| Subreddit | Best for | Promo policy - verify before posting |
|---|---|---|
| r/smallbusiness | SMB-focused tools, practical operational advice | Low tolerance for vendor pitches - answer the actual question first |
| r/ecommerce | E-commerce tooling and operations | Tool recommendations tolerated in context |
| r/shopify | Shopify-specific app/tooling products | App mentions tolerated when directly relevant to the question |
| r/freelance | Tools for independent professionals | Practical-advice culture; light self-promo in relevant threads |
| r/consulting | Tools for consultants and agencies | Professional tone expected; case-study framing works |
| r/agency | Agency-focused tooling and operations | Similar to r/consulting |
| r/humanresources | HR-tech products | Practitioner audience; value-first answers preferred |
| r/recruiting | Recruiting/talent-tech products | Similar to r/humanresources |
| r/accounting | Fintech and accounting tooling | Strict, credential-conscious community - tread carefully |
| r/personalfinance | Consumer fintech, if applicable | Very strict on self-promotion - advice-only culture |
How to actually use this list
Don't try to post in all 40. Pick the 5–8 where your actual ICP spends time, read each one's rules and last month of top posts before writing anything, and start by commenting - not posting - for a week or two to build enough account history that a future post doesn't look like a drive-by. The comment-first method applies here more than anywhere: the goal isn't to post about your product in each of these communities, it's to find the threads where someone in these communities is already describing your customer's exact problem.
Manually monitoring even 5–8 subreddits for the right moment to jump into a thread is a real time cost - this is the exact workflow ThreadyGo automates: scanning across a list like this continuously and surfacing the specific threads worth your time, instead of you checking each subreddit by hand every day.
