TOSOO

TOSOO is a neuroscience-based spin-off from ETH Zurich, focused on enhancing sleep quality through closed-loop auditory stimulation - a non-invasive technology that strengthens deep sleep by delivering precisely timed sound pulses aligned with brain activity. Our system integrates mobile brain activity measurement (EEG), real-time signal analysis, and phase-locked stimulation into a single wearable device, bringing cutting-edge sleep science into your bedroom. By boosting deep sleep brain activity, our device helps unlock the restorative functions of sleep - supporting memory consolidation, daytime alertness, cardiovascular and immune function, and neural recovery. Our technology is used by athletes and high performers to support recovery, enhance cognitive performance, and build long-term resilience. It also opens new avenues in clinical applications, including the potential to counteract neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease, and to support neurorehabilitation. Join our mission of bringing scientifically validated sound sleep into everyday life - safely, effortlessly, and effectively.
