High-converting pre-launch page.
A launch without a waitlist wastes its own hype: interest arrives, has nowhere to land, and evaporates. The teams that do this well don't just collect emails, they make the waitlist grow itself with referral mechanics: your position improves when you bring friends. That loop (the one Robinhood famously rode to a million signups) usually costs a week of fiddly edge cases. Here it's one prompt.
A premium-feeling launch page with an email signup form and the full referral loop: each signup gets a unique referral link and a live position in line, and referring people moves you up. Signups persist in a database, a live counter shows momentum, and an admin view lists everyone with their referral counts, so you can see who your real evangelists are before you launch.
Do I own the signups? Completely. The list lives in your app's database, in your infrastructure, no third-party waitlist service holding your launch audience hostage.
Can I verify the referral mechanics work? Yes, in two minutes: sign up with one email, open your referral link, sign up with a second, watch the first position improve. The admin view shows both.
What about production traffic? The blueprint ships as a working prototype in your sandbox. When you're ready for launch scale, tell the agent to swap the local database for a hosted one, that's a follow-up message, not a rewrite.
