Definition

A Painted Door Test is a demand validation method where users see and interact with a realistic product entry point before the full product exists. The key idea is to measure real intent, not opinions.

Why teams use it

Teams use Painted Door Tests to reduce wasted engineering effort. Instead of building first and discovering weak demand later, they test market response early and cheaply.

What counts as success

Success depends on pre-defined thresholds: qualified click-through rate, install intent, cost-per-intent event, and drop-off behavior across key funnel steps.

Frequently asked questions

Is Painted Door Testing the same as a fake door test?

Yes. In practice, the terms are often used interchangeably.

Can startups use this before hiring a full engineering team?

Yes. It is specifically useful before major product investment.
