Customer Interview

Prepare for a customer interview that actually changes what you think — with sharp questions, the right framing, and a synthesis doc you can act on.

What you walk away with

A real document, built from everything you worked through — then critiqued the way a tough reviewer would and polished round by round. Plus a project summary that shows your work.

16 steps in the full journey.

The first 3 questions

This is where the conversation starts. Each answer shapes what gets asked next.

  1. 01What is the product you're building, and what customer problem are you focused on right now?
  2. 02Who are you interviewing — describe the specific type of person and why they're relevant at this stage?
  3. 03What do you already know or believe about this customer, and what do you most want to test?

+ 11 more questions across discovery, validation, and the creative brief — each one adapting to what you've already said.

The first five questions of any project are free — no card required.
