How to Get Your First 100 Users for a Web Product

Your first users do not arrive because the product exists. A practical playbook for launching an MVP and finding, onboarding and keeping your first hundred users.

Launching a web product is exciting right up until the moment you realise nobody is using it. "Build it and they will come" is one of the most persistent myths in startups. Your first users don't arrive because the product exists; they arrive because you went and found them, one conversation at a time. The good news is that getting your first hundred users doesn't require a big budget or a viral moment. It requires focus, direct outreach and a willingness to do things that don't scale. Here's the practical playbook I share with founders my team and I build MVPs for.

Why the First 100 Users Matter So Much

The first hundred users aren't really about growth. They're about learning. At this stage, every user is a source of information: what they expected, where they got confused, what made them come back and what made them leave.

This small group helps you:

Find out whether the product actually solves the problem you set out to solve.
Discover the words customers use, which becomes your marketing copy.
Spot the features that matter and the ones nobody touches.
Build early advocates who recommend you to people like them.

Your first hundred users are not a marketing target. They're your most valuable research team, and you should treat them that way.

Get Ready Before You Launch

A few things are worth having in place before you start inviting people, so no effort is wasted.

Be Clear on Who It's For

"Small businesses" or "anyone who works remotely" is too broad to act on. Narrow it until you can picture specific people and where they spend time. For example, "independent physiotherapy clinics with one to five practitioners" tells you exactly who to talk to and where to find them. You can widen the audience later.

Make Onboarding Painless

Walk through sign-up as if you'd never seen the product. Remove every field and step that isn't essential. The goal is getting a new user to the core value, the moment they think "oh, this is useful," as quickly as possible.

Measure the Basics

Set up simple analytics before launch so you can see how many people sign up, how many complete the core action, and how many come back. You don't need a complex setup. You need enough to know where people drop off.

Start With People You Can Reach Directly

Your first users almost always come from direct, personal outreach. It's slow and it doesn't scale, and that's exactly why it works at this stage.

Your own network. Friends, former colleagues and contacts who fit your audience, or know someone who does.
People you interviewed while validating the idea. They already know the problem and often want to see the solution.
Your waitlist, if you built one. Invite people in small batches so you can talk to each group.
Warm introductions. Ask every early user who else they know with the same problem.

Write Outreach That Gets Replies

Personal, short messages work far better than templates. Mention why you're contacting that particular person, describe the problem in their words, and make a small, specific ask, like trying the product and sharing feedback in a short call. Avoid long pitches and never send the same message to hundreds of people.

Go Where Your Users Already Are

Once direct outreach is running, look for places where your audience gathers and contribute genuinely.

Online communities such as forums, Slack and Discord groups, Reddit communities and LinkedIn groups related to your niche.
Industry events and meetups, both local and online.
Newsletters and podcasts that your audience follows. Many welcome useful guest content.
Launch platforms like Product Hunt, which can bring a burst of attention, especially for tools aimed at makers and early adopters.

The key word is contribute. Answer questions, share what you've learned, and mention your product only where it's genuinely relevant. Communities react badly to people who show up only to promote.

Content That Works While You Sleep

Writing helpful articles about the problem your product solves is slow to start but compounds over time. Search engines and AI assistants can surface useful content to exactly the people who are looking for help. Focus on specific questions your audience asks, and answer them thoroughly and honestly.

Do Things That Don't Scale

This advice is famous for a reason. Early on, the manual effort that would be impossible with thousands of users is your biggest advantage.

Onboard users personally. Offer a short call to set up their account with them. You'll learn more in one session than from weeks of analytics.
Reply to every message quickly, ideally yourself as the founder.
Fix small issues fast and tell the user who reported them. Few things build loyalty like seeing your feedback shipped.
Check in with inactive users and ask what stopped them. The answers are uncomfortable and invaluable.

Turn Feedback Into a Routine

Keep a simple log of every piece of feedback, grouped by theme. Review it weekly with your development team and decide what to act on. Patterns across several users matter far more than one loud request.

Keep the Users You Get

Getting users to sign up is only half of it. An MVP with steady sign-ups and no retention is a leaky bucket.

Watch whether users return after their first session. That's the clearest signal the product is valuable.
Send helpful, not noisy, emails. A welcome message, a nudge to finish setup, and updates when you ship something they asked for.
Ask for referrals from happy users. A direct, personal request works better than a generic referral program at this stage.
Ask engaged users for testimonials once they've had real success with the product.

Know When to Change Course

If users sign up but don't come back despite your efforts, that's valuable information too. It may mean the problem isn't painful enough, the product misses the mark, or you're targeting the wrong audience. Talk to those users, adjust, and try again. Iterating based on evidence is the whole point of an MVP.

Wrapping up

Your first hundred users come from focus and effort, not luck: define a narrow audience, make onboarding painless, reach out personally, contribute where your users already gather, do the unscalable things, and pay close attention to retention and feedback. Treat those early users as partners and they'll shape a far better product. If you're ready to build an MVP and put it in front of real users, I'd love to build it with you and my team.
