What decision this helps you make: Whether to invest months building this, decided with evidence that costs days.

What this topic is

Validation is running the cheapest possible test that produces real evidence (payment, pre-orders, signed intent) that specific people will buy your specific offer, before you build it.

Why it matters

CB Insights' running post-mortem analysis has "no market need" among the top startup killers for a decade: teams building for months toward customers who were never there. Every one of those deaths was preventable for under $500.

Who should learn it

Anyone about to spend serious time or money on an unproven offer: first-time founders especially, who systematically overrate building and underrate asking.

What you will understand

  • The evidence ladder: what counts as proof and what doesn't
  • Four validation tests, from a $0 conversation to a paid pilot
  • How to set a pass/fail bar BEFORE running the test
  • When validation is done and building should start

Prerequisites

Common misconception

"Validation means asking people if they like my idea." Opinions are free and therefore worthless as evidence. People are kind, optimistic on your behalf, and terrible at predicting their own purchases. Validation means observing costly behavior: money paid, deposits put down, time invested, contracts signed. If it didn't cost the customer anything, it didn't prove anything.
