How to get your first 100 users
The first 100 users are the hardest to get and the most valuable, because you have no audience, no reputation, and usually no budget yet. Here is what actually moves that number without spending anything.
Start with people, not channels
Before picking a growth channel, find 10 to 20 people who plausibly have the exact problem your startup solves — former colleagues, people in a relevant subreddit or Discord, or anyone you can message directly. Talk to them one at a time. This is slow on purpose: a handful of honest conversations tells you more than a broad campaign with no feedback loop.
Free channels worth trying, in rough order
- Your own network first. A personal message to someone who might genuinely use the product converts far better than a public post nobody asked for.
- Communities where your users already are. Relevant subreddits, Discord servers, and niche forums — answer questions honestly and mention your product only when it actually helps, not as a drive-by pitch.
- Startup directories and launch platforms. A free listing (see where to launch your startup and 20 places to submit your startup) gets you in front of people actively looking for new products, and each one is a few minutes of work.
- Build in public. Sharing real progress, numbers, and setbacks on X or LinkedIn attracts people who follow the story and become early users almost as a side effect.
- Cold outreach, done narrowly. A short, specific, personalized message to 20 well-chosen people beats a templated blast to 2,000.
What to track instead of vanity numbers
Sign-ups are easy to inflate and easy to misread. Track how many people came back a second time, and ask the ones who did not why they left. A smaller number of engaged users is a better foundation than a larger number who bounced once.
Frequently asked questions
How long does it take to get 100 users?
It varies hugely by product and audience, from days to a few months. What matters more than speed is that each user came from a repeatable source you can go back to, not a one-off spike.
Should I pay for ads to get my first users?
Usually not yet. Paid ads work best once you already know which message and audience converts — spending on ads before that just buys you expensive, unclear data. Free channels are slower but teach you the same lessons for nothing.
Do the first 100 users need to pay for the product?
Not necessarily, but they need to be real and engaged, not just sign-ups. 100 people who tried the product once and left tell you far less than 20 who came back a second time.
