  6. R&D business acquired by Beacon Biosignals

    Beacon Biosignals acquires the R&D arm of Dreem, including the Dreem hardware platform and >2M nights of sleep data. The Dreem 3S goes on to receive FDA 510(k) clearance under Beacon.

Reputation

Treated as the most clinically-credible consumer sleep-EEG company of the 2010s — Dreem 2 was independently validated against polysomnography in SLEEP (2020). Consumer business never reached sustainable scale; the IP and 2M+ night dataset became Beacon Biosignals' Dreem 3S / Waveband platform.
