Your marketing team needs a case study for an upcoming campaign. You email 10 happy customers asking if they'll participate.
Two respond. One says "We need legal approval." The other says "Not interested in public promotion."
You wait 3 weeks for legal approval. It never comes. The campaign launches without the case study.
This is the case study recruitment struggle: marketing teams desperately need customer success stories, but the recruitment process is ad-hoc, high-friction, and succeeds maybe 20-30% of the time.
After recruiting hundreds of customers for case studies across multiple B2B companies, I've learned: the difference between 30% and 80% recruitment success isn't customer happiness—it's having a systematic approach that makes participation easy, valuable, and properly approved.
Here's how to recruit customers for case studies that actually get approved.
Why Customers Say No
Understand the objections:
Objection 1: "We don't want competitors knowing what we're doing"
Real concern: Competitive intelligence
How to address: Offer anonymized/industry-only case studies, strategic details removed, focus on outcomes not processes
Objection 2: "We need legal/compliance approval"
Real concern: Risk management, liability, brand protection
How to address: Provide approval-ready templates, flexible approval processes, legal-reviewed language
Objection 3: "We don't have time"
Real concern: Effort required
How to address: Minimal time commitment (30-minute interview), you do all the work, easy approval process
Objection 4: "What's in it for us?"
Real concern: No clear benefit to participation
How to address: Clear value exchange—exposure, credibility, relationship benefits
Objection 5: "We're not far enough along yet"
Real concern: Don't have impressive results to share
How to address: Focus on early wins, implementation stories, qualitative outcomes

Phase 3: Approval Process Design
Streamline approvals:
Option 1: Attribution flexibility
Offer multiple attribution levels:

Provide pre-approved materials:

- Opt-out clauses
Option 3: Multi-stage approval
Start small, expand later:
- Stage 1: Customer approves participation (no public disclosure yet)
- Stage 2: Customer approves draft content
- Stage 3: Customer approves public use (can be gated)
- Stage 4: Customer approves broader promotion
Phase 4: Interview and Creation

The Recruitment Program Operations
Build systematic recruitment:
Quarterly process:

- Week 9-12: Approvals and publishing
Target: 3-5 new case studies per quarter
Case study portfolio management:
Diversify by:
- Industry vertical (3-5 key industries)
- Company size (SMB, mid-market, enterprise)
- Use case (3-5 primary use cases)
- Geography (if relevant)
- Product tier/package
Refresh cadence:
- Update metrics annually
- Retire case studies after 2-3 years
- Refresh quotes and outcomes

The Recruitment Incentive Structure
Ways to incentivize participation:
Tier 1: Recognition
- Featured customer spotlight
- Social media promotion
- Newsletter feature
- Website showcase
Tier 2: Access and Influence
- Early access to new features
- Product roadmap input
- Exclusive events invitation
- Direct line to product team
Tier 3: Content and Exposure
- Professional case study for their use
- Speaking opportunities
- Co-marketing campaigns
- PR opportunities
Tier 4: Commercial
- Account credits
- Free training/certification
- Service upgrades
- Swag and gifts
Most effective: Combine recognition + access + content value
Avoid: Pure cash incentives (reduces authenticity)
Common Recruitment Mistakes
Mistake 1: Mass generic outreach
Sending identical emails to 50 customers yields low response. Personalized outreach to qualified candidates converts better.
Mistake 2: No clear value exchange
"Will you do us a favor?" doesn't work. "Here's what you'll get" does.
Mistake 3: Asking too much too soon
Requesting full company details and legal approval upfront scares customers. Start small, build trust.
Mistake 4: Poor execution
Taking 2 months to create draft kills momentum. Fast turnaround maintains customer engagement.
Mistake 5: One-and-done
Recruiting customers and never following up wastes relationships. Stay connected, ask for updates annually.

The Reality
Customer case studies are one of the highest-impact marketing assets. They provide third-party validation, specific proof points, and social proof that your marketing team can't create alone.
But getting customers to participate requires more than asking nicely. It requires systematic identification, compelling value exchange, minimal friction, and professional execution.
Build the recruitment program. Make it easy. Deliver value. Track results.
That's how you build a case study library that actually drives business.
