Lighthouse
Validate your idea and get your first 100 users
Ever talked to an AI agent about an idea and it told you to "build a waitlist first to validate it"?
Sounds simple. Until you actually try.
Domain. Backend. Email service. Signup form. Database. A few hours of setup at minimum, just to start collecting names. By the time it's live, half the momentum is already gone.
So I built lighthouse.
From an indie dev, for indie devs and makers.
✅ Validate your idea
Not just a waitlist. Attach survey questions (text fields, ratings, multiple choice) to every signup. By the time you hit your first 100 emails, you don't have a list. You have insight on what people actually want.
✉️ Keep your customers
Built-in newsletter. Your waitlist signups become subscribers in one click. No CSV exports, no juggling four tools, no losing momentum between "they signed up" and "they hear from you again."
💬 Grow with feedback
You can't grow if you don't know what your customers think. Lighthouse gives you a public feedback page: visitors leave an email, a rating, and what's on their mind. You reply right from the dashboard.
.📲 QR code for every page
Every page (waitlist, survey, newsletter, feedback) comes with its own. Going to a meetup? Show the QR. Coffee shop bulletin board? Print and pin. Gym, co-working space, club bathroom wall? Stick it up. Free distribution.
🎯 🔌 REST API on top of everything
Wire Lighthouse straight into your live product. Onboarding answers become segmentable, emailable data inside your app. Validate. Keep. Grow. One toolkit for the first 100 users, and what comes after.
About
After 7 indie iOS apps, every launch started the same: build a waitlist first. But that meant a domain, backend, email tool and form before I'd validated anything. Lighthouse makes that take 5 minutes, not a weekend.
