With over three decades of research in sleep neuroscience, he authored the international bestseller *Why We Sleep*. His presence and works have established the company’s theoretical foundation in sleep neuroscience.

Dr. Ram Gurumoorthy, Chief Technology Officer, brings over 20 years of commercialization experience in the field of neuroscience. He previously led brain science research at NeuroFocus (acquired by Nielsen), ensuring the successful translation and implementation of technology. As former Chief Marketing Officer of Fitbit, Chief Executive Officer Tim Rosa helped grow Fitbit into a globally leading benchmark brand in health wearables. He also spearheaded Fitbit’s acquisition by Google and its subsequent journey toward an initial public offering (IPO), bringing mature consumer-product operational thinking to the team.

“Sleep is the most important thing we can do each day to reset our brain and physical health,” says Dr. Matt Walker. Somnee exists to create better quality sleep. “We attempt to communicate with the brain in its ‘native language’—gentle, precisely timed electrical pulses—much like a conductor guiding an orchestra to harmony through subtle gestures.”

Currently, Somnee’s technological R&D relies on collaborations with institutions such as the University of California, Berkeley, and Stanford University. Somnee has published multiple research findings in authoritative journals including Frontiers in Human Neuroscience. Its products have undergone beta testing with NBA teams and their training staff; clinical validation in the professional sports sector has further confirmed the technology’s efficacy, helping to establish a complete closed loop from academic research to industrial application.

As a neuroscience-based smart sleep product, the Somnee sleep headband is a soft, lightweight, and flexible wearable device. Its headband-style design facilitates easy wear without imposing significant restrictions on users’ sleep positions, allowing for relatively comfortable use and thereby enhancing user willingness to adopt and adhere to the product.

Furthermore, the Somnee sleep headband features the following characteristics:

Precise Brainwave Monitoring: Providing Precise Targets for Intervention.The Somnee headband features built-in, laboratory-grade EEG sensors that monitor users’ brainwave activity in real time to identify individual sleep patterns. As the gold standard for classifying different stages of human sleep, EEG offers the advantage of precisely capturing subtle changes in cerebral electrical activity, thereby providing accurate targets for gentle electrical stimulation interventions.

Personalized Non-Invasive Neurostimulation for Effective Improvement of Sleep Quality.Based on EEG monitoring data, the headband acquires brainwave signals and employs machine learning to generate personalized neurostimulation protocols. It utilizes transcranial electrical stimulation (tES) technology to deliver a gentle 15-minute intervention that guides users into natural sleep. Real-world usage studies have demonstrated that Somnee can learn users’ brain rhythms and sleep patterns to optimize sleep-promoting effects. In a controlled trial involving 55 participants and over 1,800 nights of data, this technology was proven to effectively improve sleep quality and accelerate sleep onset, offering both scientific rigor and non-invasive advantages.

Companion app for timely tracking of sleep data.The headband is accompanied by a powerful app that offers features such as sleep diaries, sleep readiness scores, and EEG waveforms. Users can also build long-term health profiles by answering daily questions about factors like sleep quality and anxiety levels. The app integrates sleep assessment methods designed by Dr. Matthew Walker to help users understand how their daily behaviors impact their sleep.

Research and testing featured on the official Somnee website indicate that the Somnee sleep headband is the only sleep aid that uses personalized stimulation to directly improve sleep quality. Users need only wear it for 15 minutes to halve their sleep onset latency, increase total sleep time by more than 30 minutes, and reduce nighttime awakenings or body movements by one-third. It demonstrates significant efficacy in improving sleep efficiency and duration, outperforming melatonin, cognitive behavioral therapy for insomnia (CBT-I), and hypnotic medications.

To date, Somnee has conducted over three years of sleep research at the Advanced Sleep Laboratory in Berkeley, California, and has carried out home-based pilot studies, collecting data from more than 1,500 nights. These sleep studies and pilots were blinded, controlled trials, overseen by a Scientific Advisory Board and approved by an independent Institutional Review Board (IRB). The experiments utilized laboratory-grade EEG and EKG systems to record sleep activity, with data scored by certified polysomnographic technologists following standard medical sleep laboratory protocols.

Experimental data demonstrate the efficacy of Somnee in improving sleep efficiency and duration. In recent sleep laboratory studies (n=31) and real-world studies (n=55), comparisons between Somnee’s effects and published experimental results for melatonin revealed that Somnee is four times as effective as melatonin pills.
