Validation Methods

AI generates code, not market insight

Using AI to generate your first version and using AI to learn your market are two different activities. The code is now cheap to produce. The insight that tells you what to build is not. Founders who conflate the two end up with faster-produced products that solve the wrong problem.

Retention metrics measure staying, not succeeding

Retention metrics measure whether customers stay, not whether they succeed. A product with strong retention built on habit rather than value is one product improvement cycle away from a churn event. The distinction between customers who stay because they are succeeding and customers who stay because switching is inconvenient determines whether your retention is an asset or a liability.
