Testimonial Hero vs Case Study Buddy vs StoryVoice: Complete Comparison
An honest comparison of three different approaches to case study production: premium done-for-you, boutique writing services, and AI-powered self-serve.
Three Different Approaches
Testimonial Hero — Done-for-you video and written case studies. Professional interviewers, editors, production teams. Acquired Case Study Buddy in 2024.
Case Study Buddy — Boutique writing agency founded by Joel Klettke. End-to-end written case study production. Now integrated into Testimonial Hero.

Pricing Comparison
| Factor | Testimonial Hero | Case Study Buddy | StoryVoice |
|---|---|---|---|
| Starting price | ~$7,800/year | $4,725/project | $0 (free tier) |
| Cost per case study | $3,000-5,000+ | $4,725-10,000 | $0-25 |
Process Comparison
Testimonial Hero (4-8 weeks): Kick-off → schedule video interview → production/editing → revisions → final delivery
Case Study Buddy (3-6 weeks): Strategy call → phone interview → drafting → 2-3 revision rounds → final delivery
StoryVoice (1-3 days): Create interview → share link → customer records (5-10 min) → AI generates draft → edit and publish
Who Each Is For
Testimonial Hero: $15,000+/year budget, need video assets, want hands-off process, 3-10 flagship stories/year.
Case Study Buddy (via Testimonial Hero): Written case studies via professional writers, $5,000-10,000 per study.
StoryVoice: Volume (10+/year), budget under $5,000/year, customers too busy for scheduled interviews, building a library from scratch.
Skip the writing entirely. StoryVoice interviews your customer with voice AI for 5 minutes, then writes the publish-ready case study for you — real quotes, hard metrics, and all.
The Honest Trade-offs
Testimonial Hero: Premium-priced, and cost and timeline limit volume.
Case Study Buddy: Professional writing at a per-project price that limits to 2-4 per year.
StoryVoice: More DIY — you need someone to review and edit. No video production.
The Blended Approach
- ●Flagship video stories (top 3-5 customers, video format): Testimonial Hero, if your team has a $15K+/year budget and specifically needs video
- ●Written case studies at volume (10-50 per year): StoryVoice with internal editing
- ●Quick wins (event testimonials): StoryVoice free tier
Verdict
The tools serve different jobs. Testimonial Hero is a video production service with a high per-unit cost and 4-8 week timeline. If video format is a hard requirement and your budget supports $15K+/year, it handles that job. For teams that need written case studies at volume — 10, 20, or 50 per year on a $200/month budget — StoryVoice is the practical path. Your customer talks to an AI for 5 minutes; you get a publish-ready 800-word case study, a sales email, a LinkedIn post, and pull quotes.
