How to Run Effective Customer Interviews: A Founders’ Guide to Validating Problems
Identifying aworthy problem worth solving hinges on speaking with the right customers, asking the right questions, and conducting conversations that yield reliable data. Poorly executed interviews can produce distorted insights, require extensive cleanup, or be entirely unhelpful. This guide highlights common pitfalls and practical techniques to improve how you engage with customers and how you use what you learn.
Key challenges
– Finding the best way to talk to customers
– Determining what to do with the information gathered
– Avoiding questions and formats that lead to unreliable results
Best practices for interviewing customers
1) Avoid leading questions
Poor: “Wouldn’t you say it takes too much time to sort through startup advice?”
Better: “What’s been your experience with startup advice?”
2) Prevent wishful thinking
Poor: “How often will you go to the gym next month?”
Better: Focus on past behavior to anchor responses. “How often did you go to the gym last month?” This often reveals patterns such as, “I haven’t been there in three weeks.”
3) Probing about a prototype
Ask open, exploratory questions to uncover real needs and constraints:
– What problems would this product solve?
– When would someone truly need this? Why?
– Today, what might someone use instead to address the problem?
– Why might this new solution be better or worse?
– What barriers might someone encounter when using this product? What’s missing? What could be removed?
4) How to respond when users point out gaps
If a participant mentions something is missing, avoid affirming with “Would you use this?”
Instead respond with: “Okay, why would you want that?”
Putting it into practice
– Prepare a structured interview plan that prioritizes open-ended questions and avoids assumptions.
– Start with context: understanding the user’s role, goals, and current workflows.
– Use probing questions to explore motivations, constraints, and decision-making criteria.
– Validate, don’t persuade: seek corroborating evidence across multiple interviews and avoid seeking confirmation for your own ideas.
– Document consistently: capture themes, quotes, and observed behaviors to enable pattern analysis.
By adopting disciplined interviewing techniques, founders can gather more reliable insights, reduce guesswork, and better determine whether a problem is worth solving before investing in a solution.
