TOSOO is a Swiss neurotech company originating from ETH, UZH and USZ, with clinical studies running internationally. We build a wearable EEG platform that both measures and modulates the sleeping brain.

The platform integrates mobile EEG, real-time signal analysis, and closed-loop acoustic stimulation in a single wearable, monitoring sleep at home over days to months.

On the measurement side, it turns sleep micro- and macrostructure into longitudinal biomarkers - objective, decentralized endpoints for CNS drug development.

On the stimulation side, it delivers closed-loop acoustic neuromodulation, with sound timed precisely to the brain's slow waves to enhance slow-wave activity - the deepest stage of sleep, tied to memory consolidation and neural recovery.

This makes TOSOO more than a monitor: its neuromodulation is being explored as a potential treatment across a wide range of indications, with a primary focus on neurodegenerative diseases (Alzheimer's and Parkinson's).

One platform, two capabilities: measuring the sleeping brain as a biomarker, and modulating it as a potential treatment.
