Somnee raises $35M from Khosla Ventures for closed-loop sleep EEG neurostimulation wearable
Summary
Somnee raised $35M from Khosla Ventures, General Catalyst, and Rock Health for their closed-loop EEG-guided transcranial stimulation sleep wearable. The device enhances slow-wave sleep by synchronizing stimulation to natural brain oscillations measured in real time. Khosla's investment makes them the most active neurotech VC with simultaneous investments in Synchron (BCI), Science Corp (retinal implant), Spiro (asthma), and now Somnee (sleep).
Why it matters
Khosla's four-company neurotech portfolio covering implantable BCI, retinal prosthetics, bioelectronic medicine, and sleep neurostimulation is the most diversified neurotech bet by any single VC firm. Their portfolio construction approach — backing multiple technology bets across the brain interface space — mirrors their early AI strategy.
