How to Get Your First 100 Users for an MVP

Getting a working MVP live is a milestone. Getting the first 100 people to actually use it is a different challenge entirely, and it’s the one that catches most non-technical founders off guard. There is no algorithm, no press release, and no app store feature waiting to hand you an audience. The first 100 users almost always come from deliberate, unglamorous outreach.

This guide walks through a practical, low-budget approach to finding and winning those first users, without relying on paid advertising or a following you don’t yet have.

Why the first 100 users matter more than the number suggests

A hundred users sounds small, but it’s rarely about the number itself. It’s about what those users represent:

• Real usage data. You learn how people actually behave in the product, not how you assumed they would.
• Direct feedback loops. A small group is reachable enough that you can talk to nearly all of them personally.
• Proof of demand. Even a modest, engaged group of early users tells you more about product-market fit than any survey.
• Word-of-mouth seeds. The right 100 people, especially if they’re well-connected in their niche, can refer far more than 100 more.

The goal at this stage isn’t scale. It’s learning fast from people who genuinely have the problem your MVP solves.

Step 1: Define exactly who your first user is

Before any outreach, get specific about who you’re targeting. “Small business owners” or “freelancers” is too broad to act on. Narrow it down to something you can actually search for and message directly: “solo freelance designers who invoice clients manually” or “operations managers at 10-30 person logistics companies.”

A narrow definition makes every following step easier — you’ll know exactly where to look, what language to use, and which communities are worth your time.

Step 2: Go where your target users already gather

Rather than trying to build an audience from scratch, find the places your ideal users already spend time:

• Niche online communities: subreddits, Slack or Discord groups, industry forums, and Facebook groups built around your users’ profession or problem.
• Existing professional networks: LinkedIn connections, past colleagues, alumni groups, and industry meetups.
• Competitor or adjacent-tool communities: users of a related (non-competing) tool often share the same underlying problem.
• Q&A platforms: places like Reddit or niche forums where people are actively asking about the problem you solve.

The aim isn’t to blast a link everywhere. It’s to participate genuinely, understand what people are struggling with, and offer your MVP as a solution when it’s relevant — not as an ad.

Step 3: Use direct, personal outreach

Cold, personalized outreach consistently outperforms broad posting for early-stage products. A short, specific message to an individual who clearly has the problem will get far more responses than a generic announcement to a large group.

A simple structure that works well:

1. Reference something specific about them or their situation (not a mail-merge greeting).
2. State the problem you noticed they might have.
3. Explain briefly how your MVP addresses it.
4. Make the ask small and low-friction: “Would you be open to a 10-minute look?” rather than “Sign up now.”

Aim for quality over volume. Twenty thoughtful, personalized messages will usually beat 200 generic ones.

Step 4: Recruit a small private beta before going wide

Before opening sign-ups broadly, consider inviting a small, hand-picked group first. This lets you fix obvious rough edges, gather structured feedback, and build a handful of genuine advocates before a larger wave arrives. For a deeper look at running this stage well, see how to use a private beta for MVP validation.

Private beta users are also more forgiving of an early-stage product’s rough edges, since they know they’re joining early — which makes them a safer group to learn from than a cold public launch.

Step 5: Make it easy for early users to bring others

Once you have a small base of genuinely satisfied users, referrals become one of the most reliable ways to keep growing:

• Ask directly: “Do you know one or two other people who’d find this useful?”
• Make sharing simple with a clear invite link or a short explanation they can forward.
• Keep the ask personal rather than automated — a manual nudge from you at this stage outperforms an automated referral program built for scale.

Referrals from people who already have the problem you solve tend to convert far better than any cold channel, because the introduction carries built-in trust.

Step 6: Publish content that answers real questions

Content marketing won’t fill your first 100 users overnight, but even a few well-targeted posts can compound over time and support outreach:

• Answer specific questions your target users are already searching for.
• Share genuine lessons from building the MVP, not generic startup advice.
• Post where your audience already reads: relevant subreddits, LinkedIn, or niche newsletters, following each community’s norms around self-promotion.

Content works best as a supplement to direct outreach in the early days, not a replacement for it.

Step 7: Track where users are actually coming from

Even with a handful of users, it’s worth knowing which channel produced them. A simple spreadsheet noting the source of every sign-up (a specific community, a referral, a direct message) will quickly show which efforts are worth doubling down on and which aren’t converting. This matters more than it might seem at 100 users, because it tells you what to scale once you’re ready to think beyond the first 100. Once you cross that early milestone, deciding how to prioritize feedback after your SaaS MVP launch becomes the next practical step.

Common mistakes to avoid

Mistake	Why it hurts early growth
Targeting too broad an audience	Generic messaging convinces no one; narrow targeting converts better
Relying only on a public launch post	One-time visibility fades fast without a persistent outreach effort
Skipping personal outreach for automation	Early users respond to genuine, individual attention, not automated funnels
Ignoring where users came from	Without tracking, you can’t tell which channel is actually working
Chasing vanity sign-ups over engaged users	100 inactive sign-ups teach you less than 30 engaged early users

Bringing it together

Getting your first 100 users isn’t about a clever growth hack — it’s about narrowing your target audience, showing up in the places they already are, and reaching out directly and personally. Combine that with a small private beta and a simple referral ask, and the first 100 users tend to arrive faster than founders expect, along with the feedback that shapes what comes next. If you’re still shaping who to target before you start outreach, revisiting how to identify early adopters for MVP validation is a useful place to start.

Frequently Asked Questions

How long does it take to get the first 100 users for an MVP?

It varies widely by product and audience, but most founders take anywhere from a few weeks to a few months. The timeline depends less on luck and more on how narrowly you define your target user and how directly you can reach them.

Should I pay for ads to get my first 100 users?

Usually not yet. Paid ads work best once you already know your messaging converts and where your audience spends time. Early users are more reliably won through direct outreach, communities, and warm introductions, which also produce far more usable feedback.

What is a realistic number of users to launch an MVP with?

There is no fixed number, but a small, focused group of engaged early users is more valuable than a large group of passive sign-ups. Many successful MVPs launched to fewer than 50 people before reaching their first 100 active users.

How do I find early adopters if I don't have an audience yet?

Start with people who already have the problem you're solving: relevant online communities, forums, subreddits, industry Slack or Discord groups, and your own existing network. Direct, personal outreach to individuals almost always outperforms broad, generic posting.

What's the difference between getting users and getting customers?

Users are people who try your product; customers are people who pay for it. For an MVP, the first goal is usually usage and feedback from real users, with conversion to paying customers following once the core value is validated.
