Marketing how-to

How to write customer case studies with Claude.

Most B2B case studies are skipped by readers because they read as marketing brochures. The version that converts has specific structural rules and feels like a real story. Claude can produce these in 60 minutes from a customer interview transcript. Here is the workflow.

The premise

Why most case studies fail

Most case studies follow the same pattern: corporate intro, vague problem statement, vague solution, hype quote, generic results. Readers spot the pattern in 5 seconds and skip.

The case studies that convert have a different structure: specific situation, named protagonist, concrete moment of choice, measurable outcome with attribution, honest about limitations. Each is a story, not a brochure.

The 5-section structure

What works

1. The protagonist. Named person, specific role, specific company context. NOT "a leading [industry] company."

2. The specific moment. What was happening that made them look for a solution. Specific, dateable.

3. The decision. Why they chose us specifically. What was on the table. What almost made them pick differently.

4. The implementation. What they actually did. Real timeline. Real obstacles.

5. The outcome. Measurable. Specific. Honest about what is attributable to us vs. other factors.

The Claude prompt

From interview to case study

Write a case study from this customer interview transcript: [PASTE TRANSCRIPT]

The customer: [NAME, ROLE, COMPANY]
What we sold them: [PRODUCT/SERVICE]
When they bought: [DATE]
The measurable outcome they achieved: [SPECIFIC]

Use the 5-section structure (Protagonist / Moment / Decision / Implementation / Outcome).

Constraints:
- 600-900 words total
- Open with the specific moment, not the company description
- Include 2-3 direct quotes from the transcript (use their actual words)
- Be honest about implementation obstacles (not all rainbows)
- Measurable outcome must be attributed honestly (what we contributed vs. other factors)
- No "is pleased to announce", "industry-leading", "best-in-class"
- Read like a story, not a brochure
