SaaS founders are not all in the same sub. The funded crowd lives on r/startups. The bootstrapped crowd lives on r/microsaas and r/Bootstrapped. The marketing-focused founders camp out on r/SaaSMarketing. The big r/SaaS sub is everyone, which is why the signal is mixed. Below is the working set, with notes on which is right for which stage.
-
r/SaaS
The biggest SaaS sub. Around 300k members. Volume is high. The signal is mixed because the audience ranges from "I have an idea" to "I have $100k MRR." Mods clamp on outright self-promotion but engagement-bait posts ("how I got my first 100 users in 7 days") still dominate the front page.
Honest take: Skim, do not subscribe. The good threads are buried under generic ones. Sort by top-of-week to find the threads worth reading.
-
r/microsaas
The smaller, more focused cousin of r/SaaS. Posts about $10-50k MRR products, niche markets, and lifestyle businesses. Pricing experiments, retention tactics, and acquisition stories do well here.
Honest take: Quieter and more honest than r/SaaS. Less performance, more "here is what is actually working at $4k MRR." If you are pre-funding, this is your sub.
-
r/SideProject
Show-and-tell central. Saturday launches, "what did you build this week" threads, early-stage feedback requests. Reply quality varies. Useful for getting initial eyeballs and a few first beta signups.
Honest take: Heavy on launches, lighter on tactical advice. Use it as a launch venue, not a learning venue.
-
r/EntrepreneurRideAlong
Action-oriented sub. Founders document weekly what they are doing and what changed. Threads include MRR numbers, what worked, what did not. Lower volume, higher signal than r/Entrepreneur.
Honest take: One of the better subs for honest SaaS operator threads. Posts with concrete numbers and specific asks get real replies.
-
r/startups
Tilts toward funded and aspiring-funded SaaS founders. Threads on fundraising, hiring, equity splits, term sheets. The mod team enforces no-promotion rules tightly.
Honest take: Bad fit if you are bootstrapping. Great if you want VC-track operator chatter without leaving Reddit.
-
r/Bootstrapped
Founders intentionally not raising. The conversation is more honest because nobody is performing for investors. Posts about pricing experiments, slow growth, and the operator life do well.
Honest take: Low volume, high signal. Slow replies but every one is from someone with revenue and an opinion worth hearing.
-
r/indiehackers
The Reddit-side mirror of indiehackers.com. Smaller than the website, more focused. Monthly revenue updates, technical stack questions, "how I got my first 10 users" recaps.
Honest take: Lower volume than r/SaaS, higher post quality. The audience is closer to your size, so the advice fits better.
-
r/SaaSMarketing
Niche sub for the marketing side of SaaS. SEO for SaaS, content strategy for B2B, pricing-page optimization, signup funnel tweaks. Volume is moderate.
Honest take: Worth a weekly skim if you are running your own marketing. Not many people post, but the ones who do are usually mid-stage SaaS founders sharing real tactics.
How to find threads worth replying to
SaaS founders ask for tools constantly inside these subs. "What is everyone using for X" threads, churn fix questions, and "looking for an alternative to Y" posts run daily. Gorilla scans these subreddits (plus X, YouTube, TikTok, Instagram) for first-person demand posts and ranks them by intent. Run Gorilla on your idea →
