Sleep Tech Startup SOND Exits Stealth With $7 Million, Unveils Dreambuds
The Story
SOND, a Boston-based sleep tech startup founded by former Bose Head of Sleep Products Yadid Ayzenberg, exited stealth on Wednesday with $7 million in funding. The company introduced Dreambuds, a closed-loop in-ear system that captures physiological signals and uses AI to improve sleep. The funding comes from several investors including E14 Fund, Crosslink Capital, Ubiquity Ventures, Alumni Ventures, Meach Cove Capital, and Boston Scientific co-founder John Abele.
Key Facts
- SOND was founded by MIT graduates Yadid Ayzenberg (CEO, former Bose Head of Sleep Products) and Amir Lazarovich (CTO, former Google senior software engineering manager).
- The startup raised $7 million from E14 Fund, Crosslink Capital, Ubiquity Ventures, Alumni Ventures, Meach Cove Capital, and John Abele.
- Dreambuds capture 12 physiological signals including respiration, heart rate variability, cardiorespiratory coupling, sleep staging, body position, snoring, and seismocardiography.
- Sensor data streams in real time to a cloud-based AI sleep coach that selects or generates sleep audio programs, learning over time.
- The company has a proprietary library of over 500 audio programs; the AI coach can also generate custom sleep stories.
- Users can interact with the AI sleep coach by double-tapping the earbuds and speaking.
- The charging case includes Wi-Fi, Bluetooth, an OLED display, physical buttons, and a speaker for alarms without requiring a phone.
- The AI coach will never talk to the user unless engaged via a double-tap gesture.
