About

BrainCo develops brain-computer interface (BCI) technology and wearable devices that monitor, collect, and display real-time brain signal data, with applications spanning education, fitness, and neurological therapy. The company's product portfolio includes a prosthetic hand controlled by brain signals and an EEG headband device that monitors and collects the user's brain signal data, displaying real-time brain activity through a companion app. The headband is applicable across multiple domains: FocusEdu (designed to train students in primary and secondary education for cognitive training and attention improvement), FocusFit (to maximize workouts and recover faster through brain activity monitoring), and attenZOOM (cognitive training for students). BrainCo's technology enables users to understand and train their brain activity for improved focus, cognitive performance, and wellness outcomes. The companion app provides real-time feedback and brain activity visualization, making neurofeedback accessible to consumers rather than limited to clinical settings. The company differentiates itself through its combination of consumer-grade BCI wearables with practical applications across education, fitness, and healthcare, its prosthetic hand technology leveraging neural control, and its focus on making brain signal monitoring accessible and actionable for everyday users. Founded in 2015 and headquartered in the United States, BrainCo has raised approximately $291.8 million in a Series A round backed by Hantan Capital, Boston Angel Club, Wandai Capital, IDG Capital, Walden International, Lens Technology, OmniVision, Decent Capital, Raspberry, Tencent WeStart, Chifortune Venture Capital, and Rainmaking.
