Before you launch: the waitlist and first-hour checklist for your first 100 users
A pre-launch checklist for founders with no audience: make interest capturable, engineer the first hour, and build the early list by hand.
You are about to make a public announcement, and you have no audience. The first hour decides whether interest becomes a signup or disappears.
TypeSafe AI made Jev publicly available on 15 September 2026 after two years of stealth. In the first 24 hours, the waitlist collected over 150,000 signups. TypeSafe founder Diogo Almeida had roughly 1,500 followers on X before launch. After launch, his X follower count reached 134,021.
Vercel's data showed Jev adoption by almost 13% of paid AI Gateway teams in the first 24 hours. TypeSafe removed the Jev waitlist and said Jev was available to everyone on 21 September 2026. You do not need those numbers; you need a place where attention can land.
The first 100 users are usually earned through founder effort aimed at a narrow set of people already inclined to care, not through abstract marketing. A stranger can show interest, but only a form can keep it. The waitlist is where that effort becomes a name you can call, and the launch window starts there.
The waitlist is the capture device
Pre-launch waitlist conversion is highest when the visitor already knows the founder: 30 to 60 percent for direct traffic, 5 to 15 percent for cold social traffic, and 2 to 8 percent for paid traffic. The first 10 waitlist signups usually arrive from the founder's personal network rather than from public channels. If the page is a beautiful essay with no form, strangers have to do the work you should have done.
Keep the form to one field: email. The confirmation email has to arrive while the share window is still open, with the link and copy ready to send. If the email is slow, the share is gone.
The first hour is a designed event
A founder launch post is the moment attention becomes a decision. The reader needs a reason to trust you and a reason to try the product. Write the post as a handoff to the waitlist, with a verifiable founder credential and a concrete product claim. It should say who you are, what the product does, and where to sign up.
Before the public launch, build a qualified list. The people who will try the product are the ones you have already talked to, helped, or watched closely. The list should be short enough to call. The launch post asks them to move; the waitlist catches them when they are ready.
Manual work is the point. The early users are people you can call, ask, and help. Your first job is to answer, fix, and invite. Do not build a referral loop before you have a list of people you can call. Do not buy traffic to a page that cannot explain the product in plain words. If you cannot answer their opening question without a support ticket, you are not ready to keep them.
The launch window is a support moment. Someone will ask what it does, where the link is, and whether it works for their case. Have the answer ready.
Finish these checks before the post
Run the list below before the announcement. Each item is a quick check you can run in an afternoon. The launch window is too short to discover a missing link, a missing email, or a missing name, and the post will not fix a broken capture path.
- Put the waitlist page live before the announcement, with a visible social-proof count such as 47 signups, because that converts better than 0. A stranger can reach it, enter an email, and see the count.
- Make the confirmation email arrive instantly with a referral link and pre-filled share copy, and verify that a test signup reaches the inbox within the 60-second window.
- Write the launch post with a verifiable founder credential and a concrete product claim, such as Jev bypassing text output to return calibrated probabilities in under 0.5 seconds. A stranger can state who you are and what the product does after reading it.
- Build a first-hour seed list of founders with overlapping buyer audiences, and open the list to see names before the post.
- Set a healthy pre-launch target, thirty days out, of 50 to 150 warm names and 10 to 30 people who have actually tried the product. Keep the target in your notes.
- Plan distribution for four to twelve weeks, with two to three hours a day, and use community engagement and direct outreach for the first 5 to 20 users, the fastest early sources. Put the plan in your calendar.
