How to build a waitlist before you launch (and use it well)

A waitlist does two jobs at once: it measures whether anyone wants what you're building, and it gives you your first customers on launch day. Done well, it also tells you what to build. Here's how to start one and, more importantly, how to use it.

What a waitlist is for

• Evidence. Each signup is someone who cared enough to leave their details.
• Insight. The reasons people give for joining shape your first version.
• A launch audience. On day one you have people to tell, instead of an empty room.

Make the promise specific

"Something amazing is coming" gets few signups. A specific promise gets the right ones: who it's for, the problem it solves, and roughly what it will cost. "Invoices and payment reminders for private tutors, about $6 a month" tells the right person instantly that this is for them, and tells everyone else not to bother. That's good: you want a list of real potential customers, not a big number.

Ask one useful question at signup

Keep signup quick, but ask one question that helps you build: "What would make this a must-have for you?" or "What do you use today?". Asking what they'd pay is valuable too. On Who Wants What, people who join your waitlist can leave a note and say what they'd pay, so you collect this without building a form.

Get your first signups without ads

• Go where the problem is discussed: communities, groups and forums your users already read.
• Answer questions about the problem helpfully, and mention your project where it's relevant and allowed.
• Ask your interviewees (see validating an idea) to join and to share it with one colleague.
• Post it where people browse for new things, like the ideas being built board.

Keep the list warm

A list that hears nothing for six months goes cold. A short update every few weeks (what you built, what you learned, what's next) keeps people interested and invested. Ask for a reply now and then; the replies are often your best product feedback.

Turn signups into customers

1. Invite your most engaged signups into an early beta first, in small batches.
2. Watch what they actually use, and fix what they struggle with.
3. Offer early members something real for their patience: a founding price or extra features.
4. Ask happy beta users for a sentence you can quote, and for an introduction to one more person.

Mistakes to avoid

• Collecting emails and never writing. Silence turns interest into indifference.
• Treating signups as sales. They're interest; payment is the real test.
• Hiding the price. Signups without a price tell you about curiosity, not demand.
