Talking to Humans

The VMT Review

This is a concise and accessible field guide to customer discovery. It lacks the depth of Blank or Fitzpatrick, but it is an excellent introduction for founders who need to begin interviewing immediately.

What the Reader Will Learn

Founders learn how to identify interview candidates, structure conversations, avoid bias, listen for evidence, record insights, and decide what to investigate next. It is particularly useful as a prework assignment before a VMT discovery session.
