How to use Customer Interview Kit
- Describe who you will interview, the problem you think they have, and what they use today.
- Write your riskiest assumption and what would make you stop.
- Read the interview script and press Copy script.
- Paste the Evidence log into Notion, Sheets, or Markdown and fill it in during each call.
Tip: Ask about what people did last time, not what they would do. Past behavior is the real evidence.
Stop if…
Fewer than 4 of 10 your customer describe a specific recent time this happened.
Avoid
- "Would you use a tool that…?" — people say yes to be kind.
- "How much would you pay?" — ask what they already pay instead.
- Pitching your idea before the last section.
- Leading questions that contain the answer you want.
Commitment ladder (strongest evidence last)
- Agrees to a 20-minute call
- Shares a real example or data
- Introduces you to a peer
- Tries a prototype while you watch
- Joins a waitlist with their work email
- Pre-orders or signs a paid pilot
Interview script
Warm-up (2 min)
- What's your role, and what does a typical week look like?
- Where does the problem fit into that?
Past behavior (the core)
- Tell me about the last time you dealt with the problem. What happened?
- How often does that come up? When was the time before that?
- What did it cost you — time, money, stress? Can you put a number on the last one?
Current solutions
- What have you tried so far to solve it?
- What made you stop using the things that didn't work?
Close with a real ask
- Can I show you an early version next week and watch you try it?
- Would you pre-order or join a paid pilot if it did what you described?
- Who else should I talk to?
