HONG KONG, 12 January 2026 — BrainCo, a leading neurotechnology and brain-computer interface (BCI) startup, has filed confidentially for an initial public offering (IPO) in Hong Kong, putting the company on track to become the first of China’s much-watched “Hangzhou Six” tech pioneers to list publicly, according to people familiar with the matter.
BrainCo is advising with China International Capital Corp. (CICC) and UBS Group AG on the planned share sale, with potential proceeds expected to reach several hundred million dollars, although final terms including the size and pricing of the offering are still under discussion, the sources said.
A Breakthrough for Hangzhou’s Tech Champions
BrainCo, founded in 2015 by Han Bicheng and headquartered in Hangzhou, Zhejiang Province, develops non-invasive brain-computer interface technology and bionic limb systems. The company has positioned itself as a major challenger to U.S. competitors in the emerging BCI space, which combines neuroscience and artificial intelligence to create new ways for humans to interact with machines without implants.
The IPO filing comes amid renewed attention on China’s tech startup ecosystem and its efforts to cultivate globally competitive innovation leaders outside the usual hubs. The term “Hangzhou Six” refers to a cohort of high-profile next-generation tech firms based in the eastern city, which also includes companies in robotics, AI and spatial intelligence sectors, all vying for global leadership in deep tech innovation.
If successfully listed, BrainCo could become a bellwether for China’s ambition to foster homegrown champions in frontier technologies such as brain-computer interfaces, a field that analysts see as a future growth frontier in human-machine interaction. The company’s technology is distinct from that of implant-based rivals, focusing instead on non-invasive interfaces that can interpret neural signals via external devices, potentially broadening commercial and clinical applications without surgical procedures.
Funding and Valuation Context
Prior to the IPO move, BrainCo has attracted significant private capital. In August 2025, reports indicated the startup was in talks to raise about US$100 million in pre-IPO financing at a valuation above US$1.3 billion, underscoring investor confidence and the company’s growth prospects.
Investors in BrainCo include major venture capital firms such as IDG Capital and Walden International, and the company has expanded its footprint in Asia-Pacific by establishing operations in Hong Kong’s Cyberport, highlighting its international ambitions ahead of a public listing.
IPO Market Dynamics in Hong Kong
BrainCo’s confidential IPO filing, a preliminary step that allows companies to prepare detailed offering documents ahead of formal public disclosure, reflects Hong Kong’s continued appeal as a listing venue for Chinese tech firms. Recent deals, including high-profile floatations by AI and semiconductor companies, have contributed to expectations that total IPO fundraising in Hong Kong could reach significant levels in 2026 amid strong investor appetite.
However, regulatory review and market conditions will shape the final timing and structure of BrainCo’s listing. Unnamed sources said deliberations with advisers and potential cornerstone investors are ongoing, positioning the company to seize favourable windows for market entry.
Strategic Implications
Market participants say BrainCo’s IPO could set a precedent for other deep technology startups in China seeking public capital to fuel R&D, product development and global expansion. It also underscores broader U.S.–China competition in advanced technologies, particularly in sectors that could redefine future computing and human-machine interfaces.
For Hong Kong’s capital markets, a successful BrainCo IPO would be another milestone in attracting innovation-oriented listings and strengthening the city’s profile as a gateway for Chinese tech companies seeking international investors.
