Waitlist & Launch Manager

Build a waitlist tool with referral mechanics that helps startups go viral before launch. Full breakdown with AI build prompts.

Startups spend months building products in stealth, then launch to crickets. Building a waitlist is table stakes now, but most founders just use a Google Form or basic email capture. They miss the opportunity to create buzz and virality before launch—the exact moment when hype matters most.

Built for Developers, Solo Founders, Weekend Builders, Designers.

Viral Loops and Gleam sit at $49–$200/mo—out of reach for pre-revenue founders who need a waitlist most.

The email marketing software category is projected past $18B by 2027 (Statista); waitlist tools are the top-of-funnel wedge into that budget.

A waitlist tool with built-in referral mechanics. Users sign up, get a unique referral link, and move up the waitlist when friends join.

Suggested stack: Next.js 14 + TypeScript, Supabase, Upstash Redis, Resend, Vercel (custom domains), Stripe + PostHog. Weekend scope: about 8 hours.

  1. 1. Project Setup

    Create a Next.js app for a Viral Waitlist Manager.

The app needs:
- Public signup page with email input and optional referral code field
- Post-signup page showing: current position, referral link, share buttons (Twitter, LinkedIn, copy link)
- Leaderboard showing top 10 referrers (anonymized by default)
- Admin dashboard for waitlist owners to see: total signups, referral stats, export emails

Use Supabase for auth and database. Make the signup page embeddable as an iframe.

  2. 2. Core Feature

    Implement the referral position system:

1. On signup, create user with initial position = total signups + 1
2. Generate unique referral code (8 char alphanumeric)
3. When someone signs up with a referral code:
   - Credit the referrer
   - Move referrer up by X positions (configurable, default: 3)
   - Track referral relationship in database
4. Position calculation should be real-time based on referral count

Add API endpoint to check position and referral count for the status page.

  3. 3. Rewards System

    Add milestone rewards:
- 3 referrals: "Founding Member" badge
- 5 referrals: Early access priority
- 10 referrals: Lifetime discount unlock

Show progress bar on user's status page. Send email notifications when milestones are hit.
Allow waitlist owners to customize milestone thresholds and rewards from admin.
