The first hundred users of a new product almost never come from advertising. They come from the people you interviewed during validation, the communities where your users already gather, partners who reach your users, personal outreach one message at a time, and a product that is worth mentioning to a friend. The goal of the first hundred is not growth. It is learning who the product is for and whether they come back.
Founders often plan their first hundred users the way a large company plans a million: campaigns, channels, budgets. It does not work at that scale, and it hides the point. The first hundred users are found one at a time, by the founder, and each one is a source of information no analytics tool can provide. This is how to find them and what to do with them.
Where the first hundred actually come from
| Source | Typical yield | What it costs | What you learn |
|---|---|---|---|
| Validation interviewees | 10 to 20 | An email each | Whether the product solved the problem they described |
| Waiting list | 20 to 50 | The work you did during the build | Which message brought them, and whether they convert |
| Communities | 10 to 30 | Weeks of genuine participation | The words your users use, what they compare you to |
| Partners and referrers | 10 to 50 | A conversation and something in it for them | Which channels reach your user cheaply |
| Direct outreach | 5 to 20 | Hours of personal messages | What objections stop people signing up |
| Word of mouth | Whatever the product earns | A product worth mentioning | Whether you have something |
1. Start with the people who already told you they wanted it
If you did customer interviews during validation, you have a list of people who described the problem to you. Email each one personally: you listened, you built this, here it is, would they try it and tell you what they think. Most will. They are your best early users because they will tell you the truth. If you skipped interviews, this is the moment you find out why they matter. Our guide to validation before code is still useful after launch.
2. Work the waiting list properly
A waiting list is not a broadcast list. Send the launch email, then follow up personally with the people who did not sign up, and ask why. The reasons are your first list of objections. Follow up with the ones who signed up but did not complete the core journey, and ask what stopped them. That is your first bug list.
3. Go where your users already are
Every group of users gathers somewhere: forums, professional groups, local associations, newsletters, events, comment sections of the same three blogs. Join those places and be useful for weeks before you mention your product. Answer questions, share what you learned in your interviews, help people. When you do mention the product, do it as a member asking for feedback, not as a marketer announcing. The people who respond are close to your ideal user, and they will tell you how they describe the problem, which becomes your copy.
4. Find partners who already reach your users
Someone already has the attention of your users and does not compete with you: a supplier, a consultant, a complementary product, an association, a newsletter writer. Offer them something real: exclusive access for their audience, a revenue share, content for their channel, help with a problem they have. One good partner can deliver fifty users who arrive already trusting you.
5. Do outreach one person at a time
Find individuals who visibly have the problem, on professional networks, in public reviews of competitors, in job postings that mention the pain. Write to each one personally, briefly, about their situation, not your product. Ask if they would try it and give you fifteen minutes of feedback. Expect a low response rate and treat every reply, including the refusals, as information. The objections you hear here are the ones your landing page is failing to answer.
6. Make the product worth mentioning
Word of mouth cannot be engineered, but it can be earned and it can be made easier. Earn it by solving the problem well and by responding to every user personally in the first months. Make it easier by putting a shareable artefact in the product: a booking confirmation with a link, a result that can be sent, a profile page. Referral schemes come later, once there is something people already want to share. See what an MVP should leave out on why.
What each of the first hundred should teach you
- Who they are. Not the persona you imagined. The actual job, situation and trigger that made them try it.
- Where they came from. Ask every one. The answer tells you which channel to invest in when you have money.
- What they expected. The gap between what they expected and what they found is your product and copy backlog.
- Whether they came back. The only number that matters at this stage. If most do not, the product needs to change before the audience needs to grow.
- What they would tell a friend. If they cannot say it in a sentence, neither can your landing page.
What not to do
- Buy ads before you know who the user is and what message works. You will pay to learn what ten conversations would have told you.
- Launch a referral programme with no one to refer.
- Post in communities you joined yesterday.
- Count sign-ups instead of returning users.
- Outsource this. The founder does the first hundred. It is how the founder learns the business.
Where 7L fits
We build products, and through the Startupper Program we also help founders with market research and validation campaigns that align the ideal customer profile with the value proposition. That work is what makes the first hundred findable. If you are near launch and unsure where your first users will come from, talk to us. We have watched many founders do this well and a few do it badly, and the difference is visible in advance.
Frequently asked questions
How long should it take to get 100 users?
For a consumer product with a waiting list, a few weeks. For a business product sold through conversations, two to three months. If it takes much longer, the problem is usually the target user or the message, not the effort.
Should I offer the product free to the first users?
Free trials or founding-member discounts are fine. Entirely free, indefinitely, teaches you nothing about willingness to pay and attracts users who will leave when the price appears. Charge something, even a little, as early as you can.
Is it worth spending a small amount on ads to test?
A small spend to test which message brings sign-ups can be useful once you know who the user is. Before that, it mostly buys expensive confirmation that you do not yet know your audience.
What if my users are businesses, not consumers?
Then the first hundred are found through conversations, referrals and partners, one at a time, and it takes longer. The upside is that each user is worth more and tells you more.
When should I move from doing this by hand to scalable channels?
When you know who the user is, which message converts, which channel they came from, and that they come back. Scaling before that multiplies whatever is wrong.
