Customer Interviews That Actually Produce Insight (Not Polite Lies)

Most customer interviews fail quietly.
Not because users lie—but because founders ask the wrong questions.

Why Interviews Go Wrong

Founders often seek affirmation:

  • “Would you use this?”
  • “Does this sound useful?”
  • “What do you think?”

These questions invite politeness, not truth.

People are generous with opinions and conservative with behavior.

What Insight-Producing Interviews Look Like

Effective interviews focus on:

  • Past behavior, not future intention
  • Specific incidents, not general attitudes
  • Workarounds, not preferences

Good questions include:

  • “Tell me about the last time this happened.”
  • “What did you do immediately after?”
  • “What did you try before that?”

These reveal cost, frequency, and urgency.

Listen for These Signals

Strong signals:

  • Emotion (frustration, anxiety, relief)
  • Money spent
  • Time wasted
  • Repeated hacks or manual processes

Weak signals:

  • Compliments
  • Feature suggestions
  • Hypotheticals

Founder Discipline

Do not pitch.
Do not correct.
Do not defend.

Your job is not to persuade—it is to observe.

A founder who talks too much during interviews learns nothing new.
