You Already Have the Interview
It's called your call recordings.
The traditional case study process treats the interview as the starting point. But if you have call recordings, you have something better: unscripted, candid conversations where customers reveal how they really feel.
Where to Find Case Study Gold
Instead of scheduling a new interview, mine your existing recordings:
- Sales calls - Discovery calls capture the "before" state in vivid detail. Demo calls show what resonated. Negotiation calls often include competitive insights.
- Onboarding kickoffs - Customers articulate their goals and success criteria while they're fresh.
- QBRs and check-ins - This is where results live. Customers report progress, share metrics, and describe impact.
- Support escalations (especially resolved ones) - The thank-you after a crisis reveals genuine appreciation you'd never get in a formal interview.
- Renewal/expansion conversations - Customers justify continued investment to themselves. They articulate value in their own words.
What You're Looking For
As you review transcripts, hunt for four specific elements:
1. THE "BEFORE" STATE
How did they describe their problem? What was broken? What had they tried?
2. THE BUYING MOMENT
Why did they choose you? What differentiated you from alternatives?
3. THE "AFTER" STATE
What results have they mentioned? What's different now? What do they appreciate?
4. QUOTABLE MOMENTS
Specific praise, concrete metrics, or genuine enthusiasm. Moments of authenticity.
Why This Works Better Than Interviews
In a formal interview, customers perform. They know they're being recorded for marketing purposes. They choose their words carefully. They hedge.
In a sales call or QBR, customers are just talking. The authenticity comes through. You also get something interviews can't provide: a story that spans time.
