Cumulus Neuroscience is a neurotechnology company developing a portable EEG-based platform designed to measure brain function outside of traditional laboratory and clinical environments. The company focuses on enabling scalable, real-world neuroscience data collection through wearable hardware and cloud-based analytics.

Its system combines a lightweight, self-applied EEG headset with digital tasks and software that extract functional brain biomarkers. These biomarkers are intended to support longitudinal monitoring of neural activity and cognitive function, particularly in decentralized and hybrid clinical trial settings.

Cumulus’s platform is primarily positioned for pharmaceutical, biotech, and academic research use, where objective, repeatable measures of brain function are needed to evaluate drug effects and disease progression. The company positions itself as an enabling infrastructure layer for CNS drug development rather than a diagnostic or therapeutic provider.
