Build for one user, then scale

The fastest way to find product truth is to obsess over one user. When you solve a sharp pain for someone real, you get the blueprint for scale.

Why narrow focus works

One clear user forces clarity in copy, features, and onboarding. It removes ambiguity and makes it easier to measure success.

The depth test

• Can they complete the core action in one session?
• Do they return without being reminded?
• Would they be upset if the product disappeared tomorrow?

Scaling the loop

Once the loop is clear, scaling is simply repeating it for adjacent users. Expansion only works when the core story is consistent.
