Demand before building

Why evidence of a real problem should shape what gets built and how far it goes.

Building is often the easiest part to start. The harder question is whether the work deserves to exist.

A useful demand check does not require perfect market certainty. It requires enough evidence to answer three practical questions:

  1. Who experiences the problem?
  2. How do we know the problem matters?
  3. What action becomes easier if the problem is solved?

The goal is not to eliminate experimentation. It is to reduce unnecessary commitment. Start with the smallest useful investigation, learn from real signals, and expand only when the evidence improves.

This changes the operating sequence from technology → product → hope to problem → demand → system → action.
