BrainCo raises $280M for non-invasive brain-computer interface wearables

BrainCo, a Hangzhou-based startup and one of China's 'six little dragons' of tech, raised 2 billion yuan ($280 million) in funding co-led by IDG Capital and Walden International (founded by Intel CEO Lip-Bu Tan). The company develops non-invasive wearable devices and bionic hands using brain-computer interface (BCI) technology, positioning itself against Elon Musk's implant-based Neuralink approach. BrainCo's FDA-approved bionic hands read amputees' neural and muscular electrical signals and translate intended movements into finger motions; the company also offers wearables including a sleep aid using low-intensity electrical pulses to stimulate neurochemicals associated with stress relief.

BrainCo's core technical challenge is signal capture and decoding. Because non-invasive methods read brain signals through the skull, these signals are subtle and noisy compared to implanted electrodes. The company developed dry electrode sensors to capture signals and proprietary AI algorithms to decode them. The company's roadmap stages deployment from high-need populations (amputees with insurance coverage) to medical conditions like ADHD and depression, eventually targeting mass-market consumer electronics. BrainCo plans to license its BCI platform to third-party manufacturers as its largest long-term revenue driver.

For infrastructure and neurotechnology investors: China's government has designated BCI as a strategic 'future industry' in its latest Five-Year Plan, intensifying the US-China rivalry in brain tech. The Chinese government recently approved Neuracle Medical's minimally invasive implant for commercial use, signaling state support for the sector. As performance improvements compound and signal-processing algorithms benefit from AI advances, non-invasive BCI wearables may achieve cost and adoption curves that implant-based competitors cannot match. The market size remains speculative but could reshape human-computer interaction if practical mass-market applications emerge.
