Short answer: Reddit rewards help and bans ads. So you earn your users. Find the subreddits where your users gripe. Look for the problem you solve. Spend a week building karma by being useful. Then answer buyer-intent threads (“what tool do you use for…”). Answer in the open, where lurkers can see. Stories and data, never ads.
TL;DR
- Reddit doubles as a validation channel. Complaint threads tell you if the idea is worth building. Check before you promote.
- Pick subreddits by buyer intent, not size. A 20k niche sub asking “is there a tool for X?” beats a 3M sub that kills most promo posts.
- Credibility first: a 30+ day account with 100+ karma. Link-dropping new accounts get shadowbanned in minutes.
- The 90/10 rule is effectively dead in 2026; mods judge your whole pattern of behavior, not a ratio.
- One good comment compounds. Reddit is the #1 most-cited domain in AI answers. That means ChatGPT, Perplexity, and Google.
Why your first users are already on Reddit
Supademo’s co-founder had a free plan. He was willing to do things that don’t scale. He posted a simple offer in relevant subreddits: “Drop your product URL and I’ll build you a free interactive demo.” That offer pulled in the company’s first 2,000 signups; one thread hit 11,000 views in 24 hours. No ads, no sales team. (They’re past $4M ARR now, per Supademo’s own writeup.)
That’s Reddit’s pitch in one story. Strangers sorted into rooms by the exact problem they have. They post in public about what’s broken and what they’d pay to fix. You don’t have to find your users; they’ve lined up by topic.
The effort compounds, too. No site gets cited more in AI answers than Reddit. Think ChatGPT, Perplexity, Gemini, Google AI Overviews. AI Overviews cite it in roughly 21% of results. That comes from Karmic’s look at citation data. A helpful comment can get quoted to buyers in your space for months.
Use Reddit to validate before you promote
Almost every guide skips the step that matters most. Check that your idea is real before you chase a single user. Right now, those complaint threads are the cheapest proof of demand you’ll find.
Spend an hour just reading your target subs. Search for:
- “Is there a tool that…” / “What do you use for…”: people actively shopping for a solution
- “I hate that [existing tool] does X” / “alternative to [competitor]”: dissatisfaction you can wedge into
- “How do I…” asked over and over: a workflow people struggle with
Count them. Ten people asking “is there a tool for X” this month is real demand. You didn’t have to manufacture it. Silence is an answer too, and a cheaper one than building. Full method: how to validate a startup idea. Want tools that do it for you? Here’s an honest look at the best idea validation tools.
Why most product posts get removed
Reddit will punish anything that smells like an ad, and fast. No platform you’ve used is faster at it. The vast majority of promotional posts get removed, by mods and by automation (spam filters, shadowbans you’re never told about). The fix isn’t a better disguise. Answer questions because you know the answer, and when you mention what you built, say plainly that it’s yours.
A member answers questions with no link. It’s just a Tuesday. A member points to a competitor when it’s the better fit. A member has months of real history. Do that, and your rare product mention reads as helpful. Skip it and you’re gone in five minutes.
Find the right subreddits (score them, don’t guess)
You want to post in r/Entrepreneur. It has 3M members. That instinct is exactly backwards. Big general subs put up with the least promo. And they have the most noise. Score candidates instead of guessing — rate each signal 1–5 and multiply:
| Signal | 1 (skip) | 5 (goldmine) |
|---|---|---|
| Relevance | Tangential to your product | Members literally have your exact problem |
| Rules on self-promotion | Forbids it outright | Has a stated place for it, like a Feedback Friday thread |
| Buyer-intent density | Memes and news | People ask “what tool do you use for…” weekly |
| Signal-to-noise | Huge, every post buried in minutes | Small enough that a good post gets seen |
Some real subreddits and where they land (member counts are rough):
| Subreddit | ~Members | Read |
|---|---|---|
| r/SaaS | ~100k–150k | Core SaaS founder hub, moderate tolerance |
| r/SideProject | ~300k | Built for showing what you are working on |
| r/roastmystartup | ~50k | Feedback explicitly welcome |
| r/AlphaandBetaUsers | ~100k | For people who want early testers |
| r/micro_saas · r/NoCodeSaaS · r/B2BSaaS | ~8k–22k | Small, high-relevance niches |
| r/Entrepreneur | ~3M | Broad, low promo tolerance — comment, don’t pitch |
The niche sub where your end users hang out wins. It beats the general founder subs. Founders give feedback. Customers give revenue.
Read the room before you post anything
Drop a link from a brand-new account and you get filtered. Often you get shadowbanned. Your posts go invisible, and Reddit won’t tell you.
- A brand-new account posting a link gets filtered, and that is the platform working correctly rather than an obstacle to route around.
- Spend a week reading and commenting before you have anything to say about your own product. You will learn each room’s norms, which is the actual point.
- Write each comment for the thread it’s in. Pasting one comment across several threads is the thing every sub treats as spam, and it is treated that way because it is.
The 90/10 rule is dead (here’s what replaced it)
For years the rule was nine helpful posts for every promo post. It’s still everywhere. In 2026 it’s basically dead. Treat it as a permission slip and you’re posting by the numbers. That’s exactly what mods watch for. They judge your entire pattern, not a ratio you can game.
The replacement is harder to fake: be an actual member. If a stranger read your last three months of history, would they think “helpful person who built a useful thing,” or “account that exists to promote something”? Optimize for the first and the ratio takes care of itself.
The posts and comments that get users
The formats that convert give value even if no one clicks.
- The comment that answers a buyer-intent thread. Someone asks “what do you use for X?” Give a full answer. Include the competitors. Mention your product only if it fits, and last. The public reply, not a DM, is what spreads.
- The offer post. Supademo’s “I’ll build you a free demo” is the template. Do the work for free in exchange for feedback. Unscaleable, and that’s the point.
- The specific build story. Not “I built a marketing tool” but something much better. The detail is the credibility. “I built a tool that auto-posts your blog to 10 platforms. I was sick of copy-pasting the same thing ten times.”
A value-first comment template
For threads where somebody asked what to use. Fill the brackets, and cut anything you wouldn’t say if the product weren’t yours:
[Direct answer to their actual question — the useful part, given freely.]
For [their use case] I'd honestly look at [genuine option, even a competitor] —
it's strong at [X]. If [specific condition that matches your product], [your product]
also does [the one relevant thing], because [the specific reason it exists].
Happy to share [template / checklist / the thing] if useful.
The competitor comes before your product, and not as a tactic: if something else is the better answer for the person asking, saying so is the answer. Datadog has recommended a rival ahead of its own cheaper tool. If you can’t bring yourself to do that, you are writing an ad rather than an answer.
Turn conversations into users
Two mechanics do the heavy lifting:
- Help in the open so lurkers convert. The person you reply to is one user. The hundred people who read the thread next week are the rest.
- Keep it in the thread, not in the inbox. Answering where the question was asked is what the sub rewards, and it is what the next hundred readers find. Unsolicited DMs are the fastest way to get reported and banned.
What gets you banned (the mistakes list)
- Posting a link with no comment history in the sub.
- Copy-pasting one message across lots of subs.
- Ignoring the sidebar rules. Every sub has its own promo policy; read it.
- Using a VPN, or juggling accounts to upvote your own posts.
- Posting and ghosting. A post you don’t reply to dies; block out the afternoon.
A 7-day plan to get your first users from Reddit
| Day | Action |
|---|---|
| 1 | Validate first: read your target subs, count the “is there a tool for X” threads. Shortlist 5 subs with the scoring rubric. |
| 2–4 | Comment helpfully, no links. Build toward 100+ karma and learn each room’s norms. |
| 5 | Answer 2–3 buyer-intent threads in full, in the open, using the value-first template. |
| 6 | Post one specific build story in the sub that most welcomes them — check its rules first. Reply to every comment all day. |
| 7 | Go back to the threads that got the warmest replies and answer the follow-up questions, in the open. Note what resonated; repeat weekly. |
Days 1–30 should stay mostly promo-free. You’re earning the right to be heard. Post more offers once the community knows who you are.
Not sure your idea will land before you spend your one good Reddit post on it? Run it through the idea validation tool first. You’ll get the threads where people already describe the problem, and the subreddits most likely to want a fix.
