SOND is developing Dreambuds, a consumer sleep wearable built around in-ear biometric sensing and adaptive audio. The company is positioned in the consumer sleep technology segment, with a focus on helping users fall asleep and stay asleep through real-time interventions.

Dreambuds capture physiological signals during sleep, including respiration, heart-rate variability, cardiorespiratory coupling, sleep staging, body position, snoring, and seismocardiography. The system streams these signals to an AI sleep coach that selects or generates audio programs based on the user’s state and learned response patterns.

SOND targets consumers seeking active sleep support, refraining from medical diagnosis or treatment. The company emerged from stealth in 2026 with $7 million in funding and is launching Dreambuds through Kickstarter, placing it in an early commercial consumer-wellness category.
