Value proposition
Contactless, multimodal AI sleep management that goes beyond measurement to real-time physical intervention — analyzing sound, biosignals, and environmental data to detect and improve snoring, coughing, and irregular breathing without wearables or server uploads.
Products and solutions
TranSleep AI (free on-device smartphone app detecting snoring/coughing/irregular breathing with AI Sleep Coach), S-Pillow (AI smart pillow with 6 air cells, Samsung SmartThings compatible, sold on Samsung.com), AI하틴루 (AI Hatinroo) contactless healthcare monitoring system, XAFE (AED), radar-based contactless biosignal monitoring.
Unique value
Privacy-first on-device AI (no server uploads, only event segments stored locally) combined with closed-loop physical intervention — the app detects sleep anomalies and the S-Pillow physically reacts in real time to improve sleep, backed by 17 registered patents.
Target customer
Consumer sleep-health users (snorers, sleep-disorder sufferers, elderly/self-care), plus B2B healthcare monitoring (hospitals, care facilities, smart-home IoT).
Industries served
Sleep tech / consumer health, healthcare monitoring (hospitals, care facilities), smart home IoT.
Technology advantage
Self-developed contactless radar sensing (60GHz heart-rate/breathing), multimodal AI integrating sound + biosignals + environmental data, closed-loop AI with physical reaction, and 17 global patents. Backed by parent JM Multi (KONEX-listed) and Samsung SmartThings integration.
How they differentiate
Unlike wearable or mat-sensor competitors, Vibrest combines fully on-device privacy-preserving AI (no server uploads) with a closed-loop physical intervention system (S-Pillow reacting in real time), plus multimodal analysis of sound, biosignals, and environment — and is backed by a listed parent company.
Main competitors
Metel (ZEREMA smart pillow), TenMines (Motion Pillow AI anti-snoring), Bitsensing (radar-based sleep/wellness monitoring).
Key partnerships
