Question bank

Nine questions to validate a startup idea

Interview questions about what people did, not what they would do.

Question bank of nine interview questions for validating a startup idea, in three groups: the last time the problem happened, what people tried, and commitment.
Ask about the past and about commitment. Skip "would you use this?" Source: Koji synthesis, after Rob Fitzpatrick, The Mom Test

Nine reusable questions for the first ten customer interviews when you are testing a startup idea. They stay on what people did, what it cost them and what they already pay for, and end by asking for a small commitment such as an introduction or a pilot date. Adapted from the Mom Test approach. Use them in calls or in an AI-run interview, and keep your idea out of the conversation until the end.

  1. Tell me about the last time you ran into this problem.
  2. What did you do about it, step by step?
  3. What did that cost you in time or money?

What they tried

  1. What have you tried to fix it, and what happened?
  2. What do you use today, and what annoys you about it?
  3. Have you ever paid for anything to solve it?

Commitment
