1. Warm up before you sell anything
Reddit downgrades trust for accounts under 30 days old, so a new account that posts a link is the classic spam signal. For the first two to three weeks, do nothing but leave genuine, helpful comments and upvote good content. Aim for roughly 50 to 100 comment karma before you ever post a link. Sort by New, answer questions nobody has answered yet, and spread your activity across three to five subreddits.
2. Find the threads, not just the subreddits
Being in the right subreddit is not enough. The money is in the specific thread where you can genuinely help. A thread qualifies when one of three signals is present:
- Need — someone describes the exact problem your product solves.
- Tool request — someone asks for a tool, recommendation or alternative in your category.
- Competitor pain — someone complains a competing tool is too expensive, missing a feature, or wants an alternative.
These live all over Reddit, not only in your target subs. Searching for competitor names and for the problem itself surfaces the highest-intent threads.
3. Comment value first, mention the product last
For SaaS, comments beat posts. A helpful comment under a high-intent thread converts better, is far safer than a self-promotional post, and keeps sending you traffic for months because Reddit threads rank in Google and get cited by AI assistants. Answer the question honestly. Mention your product only when it genuinely fits, or when someone asks what you use. Never invent a story just to name it.
4. Post occasionally, and post like a human
Once your karma allows it, a text post every couple of days is fine. The posts that work read like a real experience: the problem you hit, what you tried, and what happened. Keep it short and skimmable, use a concrete number in the title when it fits, and never write a "best tools for X" roundup — subreddits auto-remove those as spam. Keep self-promotion under about 10 percent of everything you do.
5. Read the rules of every subreddit
Each community has its own posting rules: karma minimums, flair requirements, and self-promotion policies. Read them before you write. If a sub bans self-promotion, stay pure value there. Breaking a rule is the quickest path to a removal or a shadowban.
Mistakes that get SaaS founders banned
- Posting a link from a brand-new, low-karma account.
- Dropping the same link across several subreddits on the same day.
- Writing like an ad instead of a fellow founder sharing what worked.
- Ignoring the subreddit's rules and getting reported by users or mods.
The whole playbook, on autopilot
SaaS-on-Reddit FAQ
How long before I can promote my SaaS?
Two to three weeks of value comments and roughly 50 to 100 karma before any links. Promoting from a brand-new account is the fastest way to get removed.
Do comments or posts work better?
Comments. A helpful comment under a high-intent thread converts better and is safer than a self-promo post, and it keeps ranking and getting cited by AI.
Will I get banned for mentioning my product?
Not if it is genuinely relevant, rare, and follows the subreddit's rules. Keep self-promotion under about 10 percent and never spread the same link across many subs in one day.
Does Karmy post for me?
Karmy finds the threads and writes the draft so you post from your own account. An optional karmito can do the commenting and posting for you, pacing itself to stay safe.
