About Asleep

Asleep is a sleep technology company founded in July 2020 by Dongheon Lee, Junki Hong, and Jinhwan Jung. CEO Dongheon Lee, a serial entrepreneur and KAIST alumnus with a Master's in AI, previously founded two other startups before focusing on sleep technology, an area of long-standing interest. The company operates on a Software as a Service (SaaS) model, providing its technology to a range of clients in sectors like health, fitness, finance, wellness, and smart home industries.

The core of Asleep's business is its proprietary AI-powered sleep tracking technology. This system analyzes breathing sounds captured by microphone-equipped devices like smartphones to monitor sleep stages without physical contact. The technology converts breathing sounds into Mel-spectrogram images, which are then analyzed on the user's device to ensure privacy before any data is transmitted. This approach allows for the detection of sleep stages such as REM and non-REM, and can identify sleep-related respiratory issues. The company claims its technology demonstrates high accuracy, even when compared to wearable devices.

Asleep's main product offering is the AsleepTrack API, a module that businesses can integrate into their own applications and devices. This enables companies to offer personalized services based on sleep data, such as adjusting smart home environments for optimal sleep or providing tailored wellness routines. The company has established partnerships with major corporations including Samsung, LG Electronics, and a subsidiary of SoftBank Group to implement its technology. Asleep has also developed its own consumer-facing application, Sleep Routine, and a tablet called SleepBoard that automatically tracks sleep and controls smart home devices. The company has received recognition for its technology, including being selected for Amazon's Alexa Startups program and winning a CES Innovation Award.
