How It Works: 4-Step Validation

From idea to decision in 7 days. Our proven framework helps you validate with real data.

01

Create

Minutes 1-2

AI generates your landing page. No design skills needed. Publish instantly.

02

Validate

Days 1-7

Collect real email signups. Accept actual pre-orders via Stripe/Polar. See your conversion funnel in real-time.

03

Analyze

Day 7

See exactly how many visitors → emails → payments. Get automatic BUILD/KILL recommendation. Know if idea is worth pursuing.

04

Decide

Day 8+

Build it (upgrade to Pro for ongoing tools). Kill it (refund customers, learn, move on). Pivot (adjust based on real data).

Real Money > Email Signups

Payment validation is the only way to know if people will actually pay for your idea.

What is Payment Validation?

Accept pre-orders directly on your validation page

Connect your own Stripe or Polar.sh account

Your money stays in YOUR account

FastValid handles the technical integration only

Email Signups

  • Free to give
  • 90%+ never convert
  • Feels good, proves nothing

Pre-Orders (Payment)

  • Costs money
  • Real commitment
  • Proves demand

The Real Test

"If 100 people email you 'interested' but 0 people will pay $29...

That's not validation. That's a bad idea."
