SOND was founded in February 2022 by CEO Yadid Ayzenberg (formerly Bose’s Head of Sleep Products) and CTO Amir Lazarovich. Its debut product, Dreambuds, is an in-ear, closed-loop system that senses 12 physiological signals — including respiration, heart rate variability, sleep staging, body position, snoring, and seismocardiography — and streams data to a cloud-based AI sleep coach that selects or generates audio programs in real time. The AI coach can be engaged via a double-tap gesture, supports voice interaction, and draws from a proprietary library of over 500 audio programs while learning what works for each user. The Dreambuds system includes a charging case with Wi-Fi, Bluetooth, an OLED display, physical buttons, and a speaker so the system can run end-to-end without a phone. SOND has run comfort studies and betas, is accepting reservations on its website, and plans a crowdfunding campaign ahead of mass production targeted for Q2 2026.
