BrainCo develops noninvasive brain-computer interface hardware and AI-driven signal-decoding software, aiming to enable wearable BCI applications. Its notable products include an FDA-cleared bioengineered prosthetic hand that decodes nerve and muscle signals to drive individual finger movements, and a wearable device intended to improve sleep via low-intensity electrical stimulation. The company emphasizes dry-electrode sensors that capture brain signals without conductive gel and proprietary AI algorithms to improve decoding accuracy. Founded in 2015 by Han Bichen at Harvard, BrainCo relocated its headquarters to Hangzhou in 2018. Financially, the company recently completed a financing round of about ¥2 billion co-led by IDG Capital and Walden International, which the company and observers cite as supporting its commercialization and continued technology development efforts.
