BERKELEY, Calif. — The global sleep crisis has a new contender. This week, Berkeley-based neurotech startup Somnee unveiled its second-generation AI-powered smart sleep headband, a device aiming to redefine what it means to get a good night’s rest. Founded by world-renowned sleep scientist Dr. Matt Walker, Somnee first made waves in 2022 with a novel approach: pairing lab-grade EEG brainwave tracking with personalized neurostimulation to help users fall asleep faster and stay asleep longer.
With its Gen 2 release, Somnee isn’t just iterating — it’s pitching a complete paradigm shift for consumer sleep technology.
Neuroscience Meets Consumer Tech
The new Somnee second-generation sleep headband combines clinical-grade EEG+ sensors, SmartSleep AI algorithms, and closed-loop stimulation to actively guide the brain into deep sleep cycles. Unlike typical wearables that only track sleep stages, Somnee delivers targeted transcranial alternating current stimulation (tACS) personalized to each user’s brain activity.
This neurotech core is wrapped in a redesigned comfort-first form factor, complete with bone conduction speakers for meditative audio, phone-free session launches to curb late-night screen exposure, and an overhauled companion app offering detailed sleep reports and real-time insights.
“Our goal was to build the world’s most advanced AI-powered sleep wearable,” said Somnee CEO Tim Rosa. “This isn’t just an upgrade—it’s a whole new standard for how we approach sleep.”
Backed by Science—and the NBA
Somnee’s technology has been field-tested among elite athletes, including select NBA teams, through the league’s 2025 Launchpad innovation program. According to the company, early results were compelling enough that the NBA has now joined Somnee as an equity partner, alongside Khosla Ventures and TIME Ventures.
The device’s science has also been published: in Frontiers in Human Neuroscience, personalized tACS improved sleep duration by 19 minutes and reduced time-to-sleep by 6 minutes compared to fixed-frequency stimulation. Somnee claims users fall asleep twice as fast, stay asleep 30 minutes longer, and toss and turn a third less than without the device — outperforming melatonin, CBT-i, and prescription sleep aids like Ambien.
Tackling the Global Sleep Deficit
Somnee’s timing taps into a growing public health concern. Nearly one in three adults struggles with poor sleep, a factor linked to weakened immunity, emotional instability, and increased risk of chronic disease. Walker, author of the bestseller Why We Sleep and Director of UC Berkeley’s Center for Human Sleep Science, says the new Somnee represents “a meaningful, non-pharmacological step toward scalable technology that improves sleep quality.”
Somnee is positioning its device not just as a consumer gadget, but as a new category of electroceutical for sleep, protected by 24 patents and recommended by over 1,500 clinicians.
Where It’s Headed Next
Available now via somneesleep.com, Somnee will also roll out through wellness hospitality partners like the Equinox Hotel and Superpower’s biomarker-driven sleep optimization program. With the NBA’s backing, Somnee is signaling a bigger ambition: to make sleep tech as essential as fitness trackers — not just for athletes and high-performers, but for anyone chasing better rest.
For the millions navigating sleepless nights, this could be the first wearable that doesn’t just measure your sleep — it might finally fix it.
