Use this when messaging, ICP or roadmap decisions rest on guesses. Ten good interviews with recent buyers usually reveal more than a hundred survey responses.

## Inputs

- The decision the research should inform (positioning, ICP, pricing, a feature).
- Who to talk to: recent buyers (last 90 days) are best; also recent churns and lost deals.
- What you already believe, written down, so you can test it.

## The play

### 1. Recruit the right people
Recent buyers remember the story. Aim for 8 to 12 interviews across segments. Recruit with a short, honest ask:

> Hi Maya, you started with us last month. Could I ask you 20 minutes of questions about how you decided? No sales pitch, just learning. As thanks, <a small, appropriate gesture>.

### 2. Ask about the story, not opinions
Follow the timeline of the purchase:
1. **Before**: "What were you doing before? What was annoying about it?"
2. **Trigger**: "What happened that made you start looking then?"
3. **Search**: "What else did you look at? What did you almost choose?"
4. **Decision**: "What made you pick this? Who else had a say? What almost stopped it?"
5. **After**: "What's different now? What would you miss if it disappeared?"

Read [references/interview-guide.md](references/interview-guide.md) for the full guide with follow-ups and the synthesis template.

### 3. Avoid leading questions
Not "Would you say our reporting saved you time?" but "What happened the last time you needed a report?" Ask for specific past events, not hypothetical future behaviour.

### 4. Capture the exact words
Record (with permission) and pull verbatim quotes. The buyer's phrases are the raw material for headlines, emails and battlecards.

### 5. Synthesise into decisions
Group findings into triggers, alternatives, decision criteria, objections and outcomes. A theme needs 3+ interviews. Each theme ends with a recommended change.

## What good looks like

- Interviewees do most of the talking and tell stories with specific moments.
- The synthesis includes surprises, not just confirmation.
- Buyer phrases end up in the next round of copy.
- The common mistake is turning the interview into a demo or a satisfaction survey, which produces polite praise and no insight.

## Rules

- MUST get permission before recording and anonymise quotes unless the person agrees otherwise.
- MUST ask about past events, not hypothetical opinions.
- NEVER sell during a research interview.
- NEVER present a single interview as a pattern.

## Example prompts

- "Write a customer interview guide to find out why our last 20 customers bought."
- "Here are 9 interview transcripts. Synthesise themes and buyer language for our homepage."
- "Write a recruit email for interviews with customers who churned last quarter."
