SOND raises $7M for AI sleep earbuds called Dreambuds

In short: SOND, a Boston startup led by Bose’s former head of sleep products, has revealed its business and raised $7 million to build its Dreambuds sleep earbuds.

What happened

SOND says its Dreambuds are meant to do more than block noise. The earbuds collect data from the body while you sleep and then adjust what you hear in real time to help you sleep better.

The company says Dreambuds track 12 signals, including breathing, snoring, body position, and changes in heart rhythm. That information is sent to an AI sleep coach, which is software that tries to pick the right audio for you (like a personal coach, but it listens to sensor readings instead of your words).

Unlike many sleep gadgets, Dreambuds are designed to work without a phone next to the bed. The charging case has Wi-Fi and buttons, plus a small screen, so you can start, change, or resume a sleep plan without scrolling on your phone.

SOND was founded by two MIT graduates, CEO Yadid Ayzenberg and CTO Amir Lazarovich. Ayzenberg previously led sleep products at Bose and helped launch Sleepbuds 2. Investors in the $7 million round include E14 Fund, Crosslink Capital, Ubiquity Ventures, Alumni Ventures, Meach Cove Capital, and Boston Scientific co-founder John Abele.

SOND says it has run early tests and plans to move toward mass production in Q2 2026, after a crowdfunding campaign. The company is accepting reservations on its website.

Why it matters

Many people already use earbuds or white noise to fall asleep. SOND is betting that sleep audio works better when it reacts to what your body is doing in the moment, instead of playing the same sounds every night.
