Reddit Marketing for Indie Hackers

Indie hackers do not have a marketing team or a budget for ads. Reddit is one of the few places where buyers ask for a product out loud, for free. The problem is finding the right thread before it goes cold and writing a reply that does not sound like an ad.

Where do indie hackers get customers on Reddit?

Save these subreddits as one preset, then set a short freshness window so you catch posts within an hour or two. Learn how presets work on the subreddit presets page.

• r/indiehackers: Builders share revenue updates and ask what tools helped them launch.
• r/SideProject: People show off new projects and ask for early feedback or users.
• r/startups: Founders ask for advice on growth, pricing, and finding first customers.
• r/SaaS: A place to find people asking about small software tools, not just big platforms.
• r/EntrepreneurRideAlong: Builders post progress logs and ask what worked for other people.
• r/microsaas: Solo builders compare notes on small, focused products.

What does a good reply look like?

Both replies answer someone asking for a simple habit tracker app, written in two different tones.

Example (witty tone): “I have tried maybe six habit apps and abandoned all of them by week two, so take this with a grain of salt. The ones that stuck did one thing well instead of ten things poorly. Look for something with a fast daily check in, since friction is the real reason most people quit these apps, not the app itself.”

Example (educational tone): “A few things matter more than features when picking a habit tracker. First, check if it works offline, since a broken sync kills the habit of opening it. Second, look at how it handles missed days, since some apps punish you and some just move on. Third, pick one you can set up in under two minutes, or you will never start.”

How does KarmaGuy fit an indie hacker’s week?

Building a product alone leaves little time for marketing. Fifteen minutes a day is realistic, even for a solo builder.

1. Pick a slot: Do this once a day, ideally right after you check your other notifications.
2. Open your preset: Check the fresh posts KarmaGuy found in your saved subreddits.
3. Tick a few: Select the posts that are a real fit, not every one that mentions your category.
4. Draft, edit, paste: Pick a tone, tweak the wording, then post it yourself on Reddit.

What gets indie hackers banned?

• Mistake: Posting your link in every reply. Fix: most replies should help without any link. Save the mention for when it truly answers the question.
• Mistake: Using a brand new account only to promote your product. Fix: comment on a few unrelated posts first, so your account looks like a real person.
• Mistake: Copying the same reply into similar threads. Fix: rewrite each reply for that specific post, even if the question feels repetitive.
