Cash-flow businessThree paying customers in 48 hours
Kagan replaces surveys and 'would you buy this' questions with a hard test: ask for real money before building anything. Three buyers within two days means there is a business, and zero is cheap information that tells you to change the idea. The short deadline is meant to push you from polishing to asking.
