Documented cause
NightWare built an Apple Watch-based device that detects PTSD nightmares through heart rate and movement patterns and uses gentle haptic feedback to disrupt them without waking the patient. FDA-cleared in 2020, it was the first DTx (digital therapeutic) cleared specifically for nightmare disorder. But commercial success required insurer reimbursement. Despite clinical evidence, most insurers declined to cover the $329/month device, citing insufficient real-world evidence. Without reimbursement, sales stalled.
Lesson
“Digital therapeutics companies must engage payers in parallel with FDA clearance — a cleared device without a reimbursement pathway is a clinically proven product with no commercial market.”
