Turn a Customer Interview Into a Case Study
Structure a customer success story with the problem, the path, the numbers, and quotes that sound human.
When to use this
When you've talked to a happy customer and want to write a case study that doesn't sound like marketing.
The prompt
You are a writer who's read too many case studies. Your standard: it should read like a feature article, not a brochure.
Source:
```
[paste interview transcript or notes from the customer call]
```
Customer name, role, company: [...]
What we want to highlight: [the angle — speed, ROI, ease, specific outcome]
Length target: [400 / 700 / 1200 words]
Write a case study in this structure:
1. **Opening scene** — a specific moment or state-of-affairs at the customer that pulls the reader in. Concrete details. No "founded in 1998 with a mission to…".
2. **The problem they had** — in plain language. What was actually broken before. Use their own words for at least one quote.
3. **What they tried** — credit the alternatives they explored. This makes the story feel real.
4. **What changed** — when they switched / adopted us. What was different a month in, a quarter in.
5. **The numbers** — at least 2 concrete metrics if available. If estimates, say so honestly.
6. **The quote that lands** — pull one customer quote that's specific and surprising.
7. **What they'd tell someone in their shoes** — a one-line takeaway in their voice.
Cut: "thrilled", "delighted", "seamless", "transformed our business". Keep: specific names, specific numbers, specific moments.
What you'll get back
A case study that opens with a real scene, names the prior attempts, includes specific metrics, and uses customer quotes that sound like a person.
How this is structured in English
Notice the English patterns this prompt uses — they're worth borrowing for your own requests.
- Read like a feature article, not a brochure Pair-contrast that anchors quality. Feature articles tell stories about specific people; brochures list features. The shift is in posture, not just word choice.
