We test product ideas before we build them.

Most product ideas don't survive contact with real demand. Fullbook publishes a page for an idea, points a small amount of traffic at it, and measures whether anyone actually wants it — before any of it gets built.

How it works

Publish. An idea gets a page like the ones on this site — a real headline, a real price, a real signup form.
Measure. We point a small amount of traffic at it and watch what people actually do, not what they say they'd do.
Decide. Most ideas don't clear the bar and get killed. The ones that do get built.

What this is

Fullbook is a new way of deciding what to build: instead of building first and finding out if anyone wants it, we find out first. If you've landed on a Fullbook page for a specific idea, it's a live test — the product doesn't exist yet, and depending on what people do with that page, it might not.
