SOND, a sleep tech startup from Bose's former head of sleep, exits stealth with $7M | TechCrunch

Dreambuds are closed-loop in-ear earbuds that capture 12 physiological signals and respond in real time to improve sleep. The system tracks respiration, heart rate variability, cardiorespiratory coupling, sleep staging, body position, snoring, and seismocardiography from chest wall vibrations. Sensor data streams to a cloud-based AI sleep coach that selects a sleep audio program or generates one on demand. The AI learns which programs work best for each user over time. Users can speak to the AI for sleep insights or for specific programs from a library of more than 500 audio options, and can also stream podcasts through the case. The company launched with $7 million in funding from multiple investors.

"Dreambuds, a closed-loop, in-ear system that captures 12 physiological signals from the wearer, then acts on them in real-time to help consumers get better sleep. To work, the device tracks signals like respiration, heart rate variability, cardiorespiratory coupling, sleep staging, body position, snoring, and seismocardiography (SCG, or the mechanical vibrations of the chest wall produced by the beating heart)."

"This sensor data streams in real-time to a cloud-based AI sleep coach that then selects a sleep audio program, or generates one on demand, learning over time which ones work best for the individual user. Users can also interact with the AI sleep coach directly by speaking, asking for sleep insights, or for specific sleep programs from SOND's proprietary library of over 500 audio programs."

"The AI coach can also generate audio, like a sleep story with a certain theme, when asked. (Users can also opt to stream podcasts through the case, if they prefer.) Notably, the startup was co-founded and is led by CEO Yadid Ayzenberg, who previously worked at Bose as its Head of Sleep Products, where he launched Bose's Sleepbuds 2 and ran the company's portfolio of other sleep products."

"Founded by a pair of MIT grads, one who is Bose's former Head of Global Sleep, SOND emerged from stealth on Wednesday with $7 million in funding. Together with the funding, the company introduced its debut product: Dreambuds, a closed-loop, in-ear system that captures 12 physiological signals from the wearer, then acts on them in real-time to help consumers get better sleep."
