## Definition

Customer discovery is the practice of interviewing potential customers about their existing problems and workflows — rather than pitching a solution — to learn whether a problem worth solving genuinely exists.

## What it means in practice

Customer discovery inverts the instinct to pitch. The goal is to understand someone's world well enough to know whether your idea fits into it — which means the interview should be almost entirely about their existing behaviour, not your concept.

The reliable questions are about the past and the concrete: what did you do last time this happened, what does it currently cost you, what have you already tried, what did you pay for it. Past behaviour is fact. Questions about the future — would you use this, would you pay for this — invite people to be encouraging, and they reliably are.

The strongest finding is evidence of a workaround. Someone maintaining an elaborate spreadsheet, paying a contractor, or manually stitching two tools together has already proven the problem is worth effort and money. Discovering an existing workaround is far more valuable than any expression of interest in your solution.

## Worked example

Interviewing operations managers about a reporting tool.

- Weak question: 'Would you use a tool that automates your weekly reports?' — invites a polite yes.
- Strong question: 'Walk me through how you produced last week's report.'
- Answer: four hours across three tools, with a manually maintained spreadsheet bridging two of them.

**Takeaway:** The second question surfaced a four-hour weekly cost and an existing workaround — quantified evidence of a real problem, rather than a hypothetical yes.

## Common mistakes

- Pitching the idea, which turns the interview into a sales call and contaminates every answer.
- Asking hypothetical future questions instead of about concrete past behaviour.
- Interviewing people who are convenient rather than people who match the buyer profile.
- Hearing agreement as validation instead of probing for what they currently do and pay.

## FAQ

**How many customer discovery interviews are enough?**

Around 10–15 with people who genuinely match your buyer profile usually surfaces the recurring patterns. Fewer than five rarely gives enough signal to distinguish a real pattern from one strong opinion.

**What questions should you ask in customer discovery?**

Ask about concrete past behaviour: how they handled it last time, what it cost them, what they have already tried, and what they pay today. Avoid anything hypothetical about your solution.
