Effective customer interviews focus on past behavior and pain points, not future promises. Use open-ended questions like 'Tell me about the last time you experienced [problem]' rather than 'Would you buy [solution]?' Interview 15-30 potential customers, take detailed notes, and look for patterns. The goal is to understand their reality, not pitch your solution.
Key Customer Interviews Takeaways
- The Mom Test: Ask questions so good even your mom can't lie - focus on past behavior
- Open-Ended Questions: 'Tell me about the last time...' vs 'Would you use...'
- Interview Count: 15-30 interviews per customer segment for pattern recognition
- Don't Pitch: Avoid describing your solution until the end (if at all)
- Focus on Pain: Quantify the pain - how often, how severe, what's the current cost?
- Look for Patterns: 3+ people saying the same thing is a pattern worth noting
