r/SaaS: The Complete Guide for Founders and Marketers

If you build, market or sell software, r/SaaS is probably the most useful community on Reddit for you. It's where founders share revenue milestones, argue about pricing, write churn post-mortems, ask which tools to use, and occasionally post the most honest business advice you'll find anywhere online.

It's also one of the most tightly moderated business communities on Reddit. Founders show up, drop a link to their product, get removed or banned, and decide Reddit "doesn't work." Usually they just didn't read the rules, and r/SaaS has eleven of them, most of which are stricter than people expect.

This guide covers everything: who's actually in the community, every rule explained in plain English with what it means in practice, the post formats that work, the ones that get you banned, and how to use r/SaaS to learn, get feedback and find customers without burning your account.

The rules quoted here are r/SaaS's as of October 2026. Moderators update them, so always check the sidebar before you post.

r/SaaS at a glance


What it is	One of Reddit's largest communities for people building and running software-as-a-service businesses
Who's there	Founders at every stage, indie hackers, operators, marketers, and many people selling to them
What does well	Original posts with real numbers, honest lessons and specific questions
What gets removed	Self-promotion beyond the limit, AI-generated text, selling services, offers of free reviews, shortened or tracked links
Promotion limit	1 mention or 3 links every 60 days, with disclosure
Best for	Learning, feedback, and reaching buyers whose customers are SaaS founders and teams
Not for	Selling services, fundraising, or promoting marketing, outreach and lead-gen tools

Who's actually in r/SaaS

Before you post anything, know who'll read it. In practice the community breaks down into a few groups:

Early-stage founders. Pre-revenue or just past it, often solo. They ask about validation, pricing, first customers and stacks. They're the most active posters.
Bootstrapped founders with traction. Running a product with real monthly revenue. They post less often, but when they share numbers, those threads tend to be the most read.
Operators and marketers inside SaaS companies. Growth, product and customer success people looking for tactics and tools.
Service providers. Agencies, freelancers and tool makers who'd love to sell to SaaS founders. There are so many of them that several rules exist specifically to keep them in check.
Lurkers who buy. Many readers never post. They search, read recommendation threads and leave. A lot of them arrive from Google.

What this means for you: if you sell to SaaS companies (a dev tool, billing, analytics, support software), r/SaaS is full of your buyers, but you can only reach them by contributing, not by pitching. If you sell to a vertical outside software, r/SaaS is a great place to learn how to run your business, but your customers are in other subreddits.

All 11 rules, explained

Here's each rule, what it says, and what it means for you in practice.

Rule 1: Submission guidelines

Follow Reddit's site-wide rules, treat people with respect, stay on topic, and avoid non-productive self-promotion. This is the umbrella rule: everything below is a more specific version of it.

Rule 2: SaaS-relevant content only

Posts must have a SaaS angle: the SaaS ecosystem, tech companies, or the business, operational or personal side of running one. General entrepreneurship or broad news without a SaaS angle gets removed, and repeat offenders get banned.

In practice: "How I got my first 10 customers" belongs on r/SaaS only if those customers are paying for software. A generic productivity post or a general startup-news link belongs somewhere else.

Rule 3: No vendor spam in posts or comments

This is the rule that catches most marketers. Promotion is allowed occasionally, but accounts that exist mainly to promote get removed.

The limit: a maximum of 1 mention or 3 links every 60 days.
Disclosure: you must clearly disclose your affiliation at the beginning or end of the post or comment.
Alt accounts: secondary accounts promoting the same product count toward the same limit.
Value: "naked" links or bare product descriptions count as spam, even within the limit.
Penalty: a ban, and your URL gets blacklisted.

In practice: you get roughly six mentions of your product a year. Don't spend them on launch posts. Spend them where your product is the genuine answer to someone's question, and where one honest, disclosed sentence will be read by people looking for exactly that.

Rule 4: No low-effort or low-quality content

Posts and comments must add real value, and they must show original human thought. The rule specifically prohibits:

AI-generated text, "even if you made all the effort to copy-paste it yourself"
unedited prompt dumps
vague questions that a basic search would answer

The moderators also run automated tools (their installed apps include ones called Scan Slop, Bot Bouncer and Evasion Guard), so this isn't only enforced by people reading reports.

In practice: write every post and comment yourself, in your own voice. If you use AI at all, use it to check your thinking, not to write your sentences. And before asking a question, search for it. If the answer is on page one of Google, the question will be removed.

Rule 5: No selling, soliciting or fundraising

r/SaaS is for knowledge exchange, not a marketplace.

No posts or comments selling services or soliciting clients
No cold DMs to members
No asking for donations, crowdfunding, or pitching for investment
No posts designed mainly to collect emails or "testers"

In practice: if you run an agency or offer a service, r/SaaS isn't a place to find clients directly. You can still build a reputation there by answering questions in your area of expertise, and people who find your answers useful will look at your profile. But "DM me" is off the table, and DMing people who post is a fast route to a ban.

Rule 6: AMAs, surveys and polls need approval

Any research-related post (academic surveys, market research, vendor polls, "product validation" forms) and AMAs must be approved by the moderators first.

Apply through modmail, with a link to your survey and a short explanation of why it's valuable to the community.
"Validation" posts that are really lead generation or email harvesting will be rejected.
Polls without the "Mod Approved" flair are removed.

In practice: message the moderators before you post. If your survey would genuinely interest SaaS founders (and you'll share the results), it has a real chance. If it's a funnel, don't bother.

Rule 7: No shortened, obfuscated or indirect URLs

Every link must point directly to the final resource.

No URL shorteners or landing-page aggregators
No tracking or affiliate parameters: clean links only
Disguised links lead to a ban for rule evasion
Posts with shortened or indirect links are removed automatically

In practice: this catches a lot of marketers. A link with UTM parameters counts as a tracking link. If you link to anything in r/SaaS, use the plain URL. To measure traffic from Reddit, rely on referral data in your analytics instead.

Rule 8: No personal information

No real names, emails, phone numbers or private social profiles, yours or anyone else's. Redact screenshots of support tickets, emails and chat logs before posting. Mentioning a company is fine; targeting a specific employee isn't. Doxing means an immediate permanent ban.

In practice: this matters most for case-study and post-mortem posts, which often include screenshots. Blur names and emails every time.

Rule 9: Be excellent to each other

Any tone is welcome, from formal to sarcastic, as long as it's respectful. Personal attacks, harassment and flame wars are prohibited, and feedback on people's projects should be constructive. Hate speech is an immediate permanent ban.

Rule 10: No "I'll review, audit, roast or build something for you" posts

Posts or comments offering free reviews, audits, roasts or feedback on other people's products, websites or pitches are prohibited, whatever the price or intent. The moderators treat them as personal or commercial branding.

In practice: the classic agency move ("I'll audit your landing page for free, drop your link below!") is banned. If you want to help, do it in context: answer someone's existing question in the comments. That's allowed, and it's far more convincing anyway.

Rule 11: No promoting advertising or promotional SaaS

This is the strictest rule. r/SaaS doesn't allow promotion, recommendation, launch announcements, feedback requests, recruiting or user acquisition for SaaS products made for:

advertising
promotional outreach
lead or opportunity detection
ad or content generation

That explicitly includes tools that generate, suggest, schedule, automate or coordinate promotional posts, comments, DMs, replies or campaigns, on Reddit or elsewhere. Violations can mean a permanent ban and blacklisting of the tool's name and URL.

In practice: if your product is a marketing, outreach, lead-gen or content-generation tool, you can't promote it on r/SaaS at all. You can't even ask for feedback on it, and nobody can recommend it there. You can still take part in discussions as a founder, but your product stays out of it. Build your Reddit presence for it in other communities, following their rules.

The post types that work

The posts that do well on r/SaaS have one thing in common: the reader gets something even if they never click anything. These formats consistently work, and they fit the rules.

1. The numbers post

Real revenue, real growth and real costs, with the story behind them. It's the format r/SaaS rewards most, because it's the hardest to fake.

"From $0 to $8k MRR in 14 months: what worked, and the three things that wasted half a year"
"We raised prices 40%. Here's what happened to churn, conversions and support load"

What makes it work: specifics (channels, conversion rates, what each experiment cost), the failures as well as the wins, and no product link in the body. If people want to know what you built, they'll ask or check your profile.

2. The lesson or post-mortem

What went wrong, and what you'd do differently. Failure posts often outperform success posts, because they're rarer and more useful.

"I shut down my SaaS after 2 years. A post-mortem, with numbers"
"Our biggest churn driver wasn't price. It was onboarding step 3"

3. The specific question

Not "how do I get customers?" (Rule 4 will remove that), but a question with enough context that experienced people want to answer it.

"B2B SaaS, $49/mo, 30% of trials never connect their data source. What's worked for you in the first 24 hours?"
"Annual vs monthly for a $15/mo tool: did going annual-only hurt your conversions?"

What makes it work: your numbers, what you've already tried, and a clear ask. The more specific the question, the better the answers, and the more the thread gets saved and found later through search.

4. The resource post

Something genuinely useful, given away in full in the post itself: a checklist, a framework, a breakdown of data you collected.

"The cancellation survey questions that showed us why people really churned"
"What we learned from 18 months of SaaS pricing experiments"

Put the whole thing in the post. "Comment and I'll DM you the template" breaks Rule 5 and reads as lead generation, because it is.

5. The useful comment

Some of the most valuable real estate on r/SaaS is in the comments of other people's threads, especially recommendation threads. More on that below.

What gets you removed or banned

Putting the rules together, these are the posts and habits that most often end badly on r/SaaS:

The product drop. "I built [X], an AI-powered [Y]. Would love feedback! [link]." It's a naked product description under Rule 3, and it uses up your 60-day allowance for nothing.
AI-written posts. Banned under Rule 4, and caught by people and tools alike.
The free audit offer. "I'll roast your landing page" is explicitly banned under Rule 10.
Disguised market research. Surveys and validation posts without moderator approval break Rule 6.
DMing people who post. Cold DMs break Rule 5.
Tracked or shortened links. UTM parameters and link shorteners break Rule 7 and are removed automatically.
Several accounts boosting one product. Alts count toward the same limit under Rule 3, and there's a tool installed to catch ban evasion.
Any promotion of a marketing, outreach or lead-gen tool. Rule 11, with a permanent ban.

Anatomy of a great r/SaaS post

If you're writing your first serious post, use this structure:

A title with a specific claim or question. Numbers, a timeframe, a hint of the lesson: "What 6 months of cold email taught us (2.1% reply rate, 11 customers)".
Context in the first two or three lines. What you build, who for, your stage. One or two sentences, no pitch.
The substance. Numbers, story, steps, mistakes. Short paragraphs, and a few subheadings if it's long. This is 80% of the post.
What you'd do differently. Readers value this more than anything else.
A genuine question to close. It invites the comments that keep the thread alive.
No product link, unless it's one of your rare allowed mentions, it genuinely belongs, and you disclose it at the start or end.
Stay for the first two hours. Reply to every comment, including the critical ones. Early replies keep a post alive, and that's where the best conversations happen.

Write it yourself. On r/SaaS, that's a rule, not a style tip.

Comments are where reputation is built

Posts get attention, but comments build the reputation, and on r/SaaS reputation is what makes everything else work.

Sort by new and rising, not just hot. Questions with few answers are where a good reply gets seen.
Answer in your area of real expertise. If you know billing, answer billing questions. Depth beats volume.
Answer fully, without asking for anything. A complete, specific answer is the best advertisement you can run, and it doesn't count against your promotion limit.
Let your profile do the selling. A short bio saying what you do is enough. People who find your comments useful will click your name.

After a few weeks of this, people start recognising your username. That's when your own posts start getting real traction.

How to find customers on r/SaaS the right way

If your buyers are SaaS founders and teams, r/SaaS can bring you customers, but only if you work within the rules.

1. Contribute first, for weeks. With 1 mention every 60 days, you get very few chances to talk about your product. They need to land with people who already know you're helpful.

2. Save your mentions for recommendation threads. "What do you use for [your category]?" threads come up constantly, and many of them rank on Google long after they were posted. When one fits, answer the question honestly, including the alternatives, then disclose: "Full disclosure: I'm the founder of [product], which does this." That's one mention, used where it's worth the most.

3. Use one account, clearly yours. A founder's personal account with a clear bio usually works best, because the community responds to people more than logos. Never a "neutral user" persona: alts count toward your limit, and getting caught means a ban plus a blacklisted URL.

4. Keep links clean. Plain URLs only, no UTM tags, no shorteners.

5. Measure without tracking links. Watch referral traffic from reddit.com in your analytics, ask new signups where they heard about you, and keep an eye on branded searches. Reddit's effect is often indirect: people read a thread, Google you a week later, and sign up "directly."

New accounts and the warm-up

Like most large subreddits, r/SaaS is protected by automated filters, and its installed apps are built to catch bots and ban evasion. A brand-new account that posts straight away is the profile those systems are designed to stop.

So warm the account up before you need it. Comment helpfully, in r/SaaS and in other communities related to your expertise, for several weeks before your first post. Fill in your profile. Don't post links early.

One habit worth building: after you post or comment, open the thread in a logged-out browser window. If you can't see your contribution, it was filtered. Message the moderators politely instead of reposting.

Using r/SaaS for research

Even if you never post, r/SaaS is one of the best free research tools in software.

Find out what people say about your competitors. Search the subreddit for their names. Complaints in those threads are your positioning.
Test pricing reactions. Search "pricing" plus your category to find founders' real reactions to price changes, per-seat models and usage-based billing.
Collect your buyers' language. The exact words people use to describe their problems are the words your landing page should use.
Use Google for better search. Reddit's own search is limited. Searching Google for site:reddit.com/r/SaaS [topic] usually finds the best threads faster.

r/SaaS and AI search

There's one more reason r/SaaS matters more in 2026 than it did a few years ago. When someone asks ChatGPT, Perplexity or Google "what's the best [tool] for a small SaaS?", Reddit threads are among the sources those answers draw on, and r/SaaS recommendation threads are exactly the kind that get used.

That means a helpful, honest, disclosed comment in the right r/SaaS thread can shape what AI tools tell your future buyers, long after the thread has left the front page. It's also why a negative thread about your product deserves a calm, open reply rather than silence.

r/SaaS is strict partly because so many people want to promote there. Other founder communities have different cultures and different rules, so read each one's sidebar before posting:

r/startups: broader than SaaS, focused on early-stage questions.
r/Entrepreneur: very large and general, every kind of business.
r/indiehackers: bootstrapped and solo founders, building in public.
r/microsaas: small, often solo-run SaaS products.
r/SideProject: built specifically for showing off things you've made.
r/EntrepreneurRideAlong: founders documenting their journey as they go.
Your buyers' own communities: if you sell to marketers, developers or sales teams, the subreddits where they spend time often matter more than any founder community.

Common mistakes, and what to do instead

Mistake	Do this instead
Launching your product in a post	Contribute for weeks; save mentions for recommendation threads
Mentioning your product every week	Stay within 1 mention or 3 links every 60 days
Forgetting to disclose	Disclose at the start or end of the post or comment
Writing with AI	Write it yourself; Rule 4 bans AI-generated text
Offering free audits or roasts	Help in existing threads instead (Rule 10)
Posting a survey or validation form	Get moderator approval through modmail first
UTM-tagged or shortened links	Plain, direct URLs only
DMing people who post	Reply publicly in the thread
Several accounts, one product	One account, clearly yours

FAQ

Can I promote my SaaS on r/SaaS? Yes, occasionally: up to 1 mention or 3 links every 60 days, with your affiliation disclosed at the start or end, and with real context and value. Unless your product is an advertising, outreach, lead-gen or content-generation tool: those can't be promoted at all.

How do I disclose my affiliation? Say it plainly at the beginning or end of the post or comment, for example: "Disclosure: I'm the founder of [product]."

Can I post my product for feedback? A feedback request about your own product counts as a mention under Rule 3, so it uses up your allowance and needs real context. For marketing and lead-gen tools, feedback requests aren't allowed at all.

Can I offer free audits or reviews to get clients? No. Rule 10 bans offers of free reviews, audits, roasts or feedback, whatever the intent. Help people in existing threads instead.

Can I run a survey or validate an idea? Only with moderator approval. Message the mods with a link and a short explanation of why it's valuable to the community.

Can I use AI to write my posts? No. Rule 4 bans AI-generated text, and the moderators use tools to detect it.

Why was my post removed? The usual reasons: self-promotion over the limit, no disclosure, AI-generated or low-effort text, a link with tracking or a shortener, or an account the filters treat as too new. Message the moderators and ask what to change.

Should I post from a personal account or a brand account? For r/SaaS, a founder's personal account with a clear bio usually works best. A clearly branded account is fine for answering questions about your product. What never works is pretending to be a neutral user.
