Getting Your First 100 Users With No Audience and No Ad Budget

The advice you get about acquisition is mostly written for companies that already have something. SEO needs domain authority you accumulate over a year. Paid ads need a budget and a converting funnel. Outbound needs a list and deliverability infrastructure. Content marketing needs either an audience or the patience to build one over eighteen months.

At zero, none of these are available to you. What is available is the thing that doesn't scale: going to where the conversations already are and being useful in them.

Why cold-start works differently

The insight that makes this viable is that you don't need an audience if you borrow one. A thread on r/SaaS with 200 comments has an audience. Your reply to it gets read by people who came for the thread, not for you. This is why community replies work at zero followers when posting to your own empty timeline does not.

It also means the quality bar is different. On your own channel, mediocre content just gets ignored. In someone else's thread, a bad reply gets downvoted and actively costs you. The trade is: free distribution, in exchange for having to actually be good in each individual instance.

The arithmetic, honestly

Let's be concrete, because vague optimism about this channel is why people abandon it.

A reasonable week for a founder doing this properly: you surface maybe 15–25 genuinely relevant threads, you reply to 8–12 of them, you get meaningful engagement on perhaps half, and you convert somewhere between zero and three sign-ups. Some weeks it's zero. The good weeks are driven by one thread that happened to be read by the right people.

At that rate, 100 users takes months, not weeks. Anyone telling you otherwise is selling something. What makes it worth doing anyway is the shape of the curve: unlike a launch spike, this doesn't decay. The threads you reply to stay in Google. Month six is better than month one, because you've accumulated presence, credibility, and a much better sense of which phrasings convert.

Where to spend the effort

Pick three communities. Not fifteen. Being a recognisable regular in three subreddits is achievable in a couple of months. Being an occasional stranger in fifteen achieves nothing — you get no accumulated credibility anywhere, and strangers get less benefit of the doubt.

Prioritise narrow over large. A thread in a 40,000-member niche subreddit where you're one of four replies will outperform a thread in a 2 million-member general subreddit where you're one of ninety. Smaller communities also have longer thread lifetimes, which relaxes the response-time pressure considerably.

Track intent phrases, not your product name. Nobody searching for a solution knows your product's name. They're writing "is there something that does X" and "what do you all use for Y". Brand-mention alerting misses essentially your entire addressable market at this stage, because you have no brand yet.

The first month should be research

Here's the reframe that makes the slow start bearable. In month one you are not really doing acquisition — you are doing customer research with a chance of acquisition attached.

Every thread you surface tells you something: the words people use for the problem (rarely the words you use), the alternatives they already know about, the objections that come up unprompted, the constraint that actually drives the decision — usually price or migration cost, rarely features.

Founders who treat the first month this way tend to rewrite their landing page around week three, and the rewrite is usually the thing that starts converting. The leads didn't do that. Reading the threads did.

What to actually do each day

1. Look at the surfaced threads once, in the morning. Not throughout the day — this channel expands to fill available time and will eat your building hours if you let it.
2. Pick the two or three highest-intent ones. Ignore the rest without guilt.
3. Write real replies. Ten minutes each, not two.
4. Note anything interesting about how the person described their problem.
5. Close the tab and go build.

Twenty to thirty minutes a day. The failure mode is not doing too little of this — it's doing an hour a day for two weeks, burning out, and doing none of it for the next three months.

When to stop and do something else

If after two months of consistent effort you're getting engagement but no sign-ups, the problem is not the channel. Either the threads you're matching aren't really your buyers — narrow the keywords — or the landing page isn't converting people who arrive warm, which is a much bigger and more useful thing to learn.

If you're getting neither engagement nor sign-ups, your replies are probably reading as promotional. Have someone else read three of them and tell you honestly.

Brew Me A Coffee handles the surfacing part — continuous scans across Reddit, Hacker News, and GitHub Discussions, with each candidate scored for relevance, intent, and urgency so your daily twenty minutes goes to replying rather than searching. The free plan covers one product, which is all you need to find out whether this channel works for you. There's a fuller breakdown on the indie hackers page.
