About the Company

Brain Co.

Non-invasive BCI and EEG prosthetics

BrainCo develops non-invasive brain-computer interface (BCI) technology that translates EEG and muscle signals into commands for external devices. Its product line includes the BrainRobotics hand, an FDA-certified prosthetic that uses AI to decode muscle signals to control individual fingers for tasks like writing or playing piano, and EEG headbands such as FocusCalm, Eassleep, and OxyZen for education, focus, sleep, and meditation. The company combines medical devices with wellness and learning tools, delivering neurotechnology through devices that capture brain or muscle activity and turn it into actionable feedback or control signals. Its goal is to broaden access to advanced neurotech by offering capable prosthetics and BCI solutions at a more affordable price while expanding applications in health, learning, and well-being.
