What

What it is

A short research pass that turns ideas into testable problems with buyer signals. It helps you choose one niche based on evidence, not hype.

What it is not

It is not brainstorming features or chasing trends without proof.

2-minute theory

Buyer signals show that people already pay or actively seek a solution.
A narrow niche makes outreach and sales easier to start.
Clear problems shorten feedback cycles and reduce wasted build time.

Key terms

Buyer signal: Evidence that people already pay or actively seek a solution.
Niche: A focused user group with a shared problem and context.
