Documented cause
Eko Devices built digital stethoscopes integrated with AI to detect cardiac abnormalities like atrial fibrillation and murmurs. The technology received FDA clearance and was clinically validated. The company raised $165M. But hospital adoption required integration with EHR systems, new clinical protocols, physician training, and procurement committee approvals that each took 12-18 months per institution. The reimbursement pathway for AI-assisted cardiac screening was still being established. Revenue grew but not fast enough to justify the capital deployed, and the company began restructuring in 2024.
Lesson
“AI stethoscope commercialization requires a reimbursement-first strategy — without a CPT code, physician incentive to adopt is near-zero.”
