How to get your first 100 users for an app or SaaS
Short answer: the first 100 users come from manual work, in three stages. Get the first 10 from people you can message directly. Get the next 40 from communities where strangers describe the problem your app solves. Get the rest from founder-led posts, small creators and launch platforms once you know which message works. Count activated users, not signups.
This plan is for solo founders and small teams with a working product. The stage sizes are a rule of thumb, not a forecast.
Stage 1: Users 1–10, people you can message
Write down everyone you know who has the problem, or knows someone who does: former colleagues, friends in the industry, people you have talked to online. Message each one personally: what you built, the one task it does, and a question (“would this help with X?”). Offer to set it up with them on a call. Watch where they get stuck.
These users will be forgiving, which makes their feedback useful and their usage misleading. Treat it as learning, not validation.
Stage 2: Users 11–50, communities with the problem
Search communities for people describing the problem in their own words, and reply with real help plus a disclosed mention of your app (see how to promote your app on Reddit). Strangers who sign up from a reply are the first honest signal that your message works. Track which community and which kind of question each signup came from.
Stage 3: Users 51–100, content, creators and launches
- Founder-led posts: share what stages 1 and 2 taught you. See founder-led content.
- Small creators: pitch creators whose audience has the problem. See how to find influencers.
- Launch platforms and directories: list the product where your buyers browse, with the message that already converted.
- Search: write one page that answers the question your users asked most.
A weekly plan
| Week | Focus | Daily work |
|---|---|---|
| 1–2 | Personal outreach | 5 personal messages, 1 onboarding call |
| 3–5 | Community replies | 5–10 helpful replies in the communities that fit |
| 6–8 | Posts and creators | 1 founder post, 3 creator pitches |
| Every Friday | Review | Count activated users per source, keep the best one, drop the worst |
Measure the right thing
Record every user’s source and whether they completed the first useful task. The free first-user experiment tracker has the columns. When one source produces most activated users, put most of your time there.
Where AI and Crany fit
Stages 2 and 3 are where founders run out of time: finding threads every day, writing replies and posts, pitching creators and keeping track. Crany.ai, an AI marketing co-founder in development by Tangenix, is being built to run those channels with your approval and tell you which source brings users that stay. It is not publicly available yet; join the free waitlist.
Questions founders ask
What is the fastest way to get the first 100 users?
Direct, manual outreach to people who have the problem: message people you know who fit, then reply in communities where strangers describe the problem. It does not scale, and that is the point. The first 100 teach you who your product is for and what message works.
Should I launch on Product Hunt to get my first users?
A launch platform can bring a spike of visitors, many of whom are other founders rather than your buyers. Launch after you have a few active users and a clear message, and treat it as one channel among several, not the plan.
Do I need paid ads to get my first 100 users?
Usually not. Paid ads work better once you know which audience and message convert. Before that, ads mostly buy expensive lessons that free channels such as replies, posts and direct messages can teach you for time alone.
What counts as a user?
Count people who completed the first useful task in your app, not signups or visits. One hundred activated users who came back is a different business from one hundred email addresses.
