AI-powered sleep apnea detection
from audio alone
80–90% of sleep apnea cases remain undiagnosed. Polysomnography costs $3,000. NEEND costs a microphone.
Sleep apnea is a silent epidemic
Americans are affected by sleep apnea
sleep clinics nationwide to serve 46M+ patients
NEEND replaces polysomnography with a microphone
How NEEND detects apnea events
31M-parameter self-supervised transformer
Trained on 22,000+ hours of overnight audio using masked spectrogram modeling. The model learns to reconstruct masked portions of spectrograms, developing deep representations of normal and abnormal breathing patterns without requiring labeled data.
14 Audio Biomarkers
Training Data — 5 Public Datasets

Intelligent sleep correction wearable
A chest-worn, non-invasive device that detects apnea events in real-time and issues haptic feedback to encourage breathing recovery. Not a medical device. An intelligent sleep correction system.

Closed-Loop Detection System
Proxy SpO₂ via signal fusion: no pulse oximetry needed on the chest
Gamification that actually works
Users receive a simple 0–100 score to monitor improvement
All participants showed statistically significant improvement
Average point increase in the 20–30 year old cohort
