SOND exited stealth with $7M and introduced Dreambuds, a closed-loop in-ear system that captures twelve physiological signals overnight and adapts audio in real time through a cloud-based AI coach. The company was founded by Yadid Ayzenberg, Bose's former head of sleep products, and the round drew E14 Fund, Crosslink Capital, Ubiquity Ventures, and Boston Scientific co-founder John Abele. Mass production is targeted for Q2 2026 following a planned crowdfunding campaign. The launch drew substantial interest. Interestingly, the Dreambuds do not seem to integrate electrodes to measure the brain directly.
