Wesper Inc.

Wesper Inc. is an FDA-cleared provider of at-home sleep apnea testing (HSAT) using wearable patch technology. The company delivers Level 3 clinical-grade diagnostic data for sleep disorders without the constraints of traditional polysomnography or conventional home sleep tests. Wesper's proprietary flexible patch-based system captures comprehensive signals including thoracic and abdominal respiratory effort, airflow, oxygen saturation (SpO2), heart rate, sleep staging, body position, snoring, skin temperature, and leg movement analysis. The platform generates 45 longitudinal trend metrics, including AHI 3%/4%, hypoxic burden, ODI, RDI, central apnea index, and T90, delivered through cloud-based provider portals with autoscored and overscored reporting capabilities. The device employs durable silicone construction with gentle adhesives designed for all-night wear across diverse patient populations. Wesper reports a 99% patient success rate and has conducted validation studies comparing its technology to polysomnography across varied demographics (age, ethnicity, BMI, comorbidities). The company markets to sleep medicine practices, primary care providers, and health systems. Regulatory approval includes FDA 510(k) clearance. Clinical evidence and validation documents are published and available for provider review.
