Everyone does customer interviews. That part is not the problem.

The problem is what you walk out with. You get on a call, the customer talks for forty minutes, you nod, you take notes and you hang up with a feeling. The real signal was in there: the moment they mentioned a workaround they’ve been using for two years, the throwaway comment about their boss, the thing they said at minute thirty-eight that contradicted everything they said in the first ten minutes. You heard it. You didn’t catch it.

The insight that changes a roadmap decision is almost never the one the customer leads with. It’s buried. It requires pattern recognition across ten conversations, not one.

Claude fixes the part between the conversation and the decision. With the right setup it helps you:

  • Ask the right questions based on your specific product hypotheses

  • Process every transcript into structured signal in minutes

  • Find the patterns that repeat across 10-20 interviews

  • Turn the research into concrete product decisions

This guide builds that system with the exact prompts for each step.

Inside you will find:

  1. How to Set Up Your Research Project

  2. How to Write the Context Files Without Staring at a Blank Page

  3. How to Build the Interview Guide with Claude
