If you ask people whether they like your idea, most will say yes to be nice. A good customer interview avoids that trap. You talk about their life and their problem, and you barely mention your solution.
Three rules
- Ask about the past, not the future. What someone did last month is a fact. What they say they'll do is a guess.
- Talk about their problem, not your idea. Save the pitch for the end, if at all.
- Listen more than you talk. Aim for them speaking 80% of the time.
Questions to ask
- Tell me about the last time you ran into this problem. What happened?
- How did you deal with it? What did you try?
- What does it cost you today, in time, money or stress?
- Have you paid for anything to solve it? Why that, and why not something else?
- What's the hardest part about it?
- How often does it happen?
- Who else is involved when it comes up? Who decides what to buy?
- If you could wave a magic wand, what would change?
- Who else should I talk to about this?
Questions to avoid
- "Would you use an app that...?" Everyone says yes.
- "How much would you pay for this?" People guess low or high, never accurate.
- "Don't you think it would be great if...?" A leading question gets the answer you want, not the truth.
How to run it
- 1Keep it short20–30 minutes, ideally a call or in person. Ask for advice, not a sale: people like helping.
- 2Two people, one talksIf your co-founder joins, one asks questions and the other writes notes word for word.
- 3Dig deeperWhen something sounds important, ask why, and then ask for an example.
- 4Write it up the same dayThree bullets: the biggest pain, what they do today, and the strongest quote.
- 5Ask for a next stepCan you show them something in two weeks? Can they introduce you to a colleague? A yes is a signal.
After 10 interviews you should be able to describe your customer's problem in their own words. If you can't, keep interviewing before you build.
