A healthcare company commissioned AI agents to explain bills to patients, arrange payment plans, and reconcile payments back into providers' billing systems. The system has since handled 61,246 AI voice calls.
Because mistakes could mean double-charging patients, updating wrong records, or unbalancing providers' books, the team scaled QA alongside AI-assisted development:
- 349,000 lines of application code vs. 343,000 lines of test code (nearly 1:1)
- 13,650 automated tests running continuously
A notable case study of enterprise AI agent deployment where test investment matches development speed.
