Beta users are the people who use your product before it's finished and tell you what's wrong with it. You don't need many. Ten engaged beta users who have the problem teach you more than a thousand signups who signed up out of curiosity.
How many beta users do you need?
For most early products, 10 to 30 active beta users is plenty. You want enough to see patterns in feedback, but few enough that you can talk to every one of them personally. More than that and feedback turns into noise you can't follow up on.
Where to find them
1. People who already told you about the problem. If you did any customer research, start there. They're the most motivated testers you'll get.
2. Your own network. Post about what you're building on LinkedIn or X, describing the problem and who it's for. Ask people to reply or forward it to someone who has the problem.
3. Communities where your users gather. Subreddits, Slack and Discord groups, forums, Facebook groups. Ask for feedback openly and follow each group's rules. See how to use Reddit to get your first users.
4. A waitlist page. A simple landing page explaining the problem and offering early access. Share it everywhere above. Ask one question on signup ("How do you handle X today?") to filter for people who really have the problem.
5. Direct outreach. Find people who visibly have the problem and send a short personal message asking if they'd test it. Short, specific messages work: see how to use cold email.
Choose the right testers
Prioritise people who:
- Have the problem now, and feel it often.
- Are currently solving it some other way: a spreadsheet, a competitor, a manual process.
- Will actually use the product for real work, not just click around once.
Friends who are being nice are the least useful testers. They'll tell you it's great.
What to give them
- A clear job to try: "Use it to send your next three invoices," not "have a look around."
- A direct line to you: your email, a chat group, or a weekly call slot.
- Something in return: free access during beta, a lifetime discount, or a say in what gets built.
What to ask them
Watch what they do more than what they say. Useful questions:
- "Walk me through the last time you dealt with [problem]."
- "What did you try to do first? Where did you get stuck?"
- "What would you use instead if this disappeared tomorrow?"
- "Would you pay for this? How much would feel fair?"
The last question is unreliable on its own, but the answer to "what would you use instead" tells you who you're competing with.
Turn beta users into customers
Before the beta ends, tell testers when it will and what the price will be, and offer them a founding discount for converting. The share who do is one of the best early signals of whether you've built something people need. If almost nobody converts even with a discount, that's important to know before you spend money on launch. See how to turn free users into paying customers.
Common mistakes
- Waiting until the product is "ready." Beta testers expect rough edges. Start as soon as it does one useful thing.
- Too many testers, too little contact. A hundred silent testers teach you nothing.
- Collecting feature requests instead of problems. Ask what they were trying to do, not what button they want.
