BrainCo raises $286M Series C — largest non-US BCI round ever co-led by IDG Capital and Walden International
Summary
BrainCo raised $286.3 million in a Series C round co-led by IDG Capital and Walden International, with Tencent Investment and Sequoia China, in January 2026. This is the largest BCI funding round outside the United States in history and one of the five largest neurotech rounds ever. Funds will scale BrainCo's non-invasive BCI and EEG platform across Chinese education, healthcare, and consumer markets.
Why it matters
BrainCo's $286M round from top-tier Chinese VCs represents China's most significant single bet on domestic BCI leadership. Combined with the government's national neurotech plan, this creates a well-funded Chinese BCI ecosystem that will compete globally across EEG wearables, prosthetics, and consumer brain health applications.
