Kunwei raises ¥400M for low-frequency transcranial brain imaging

KEY FACTS

  • Kunwei Technology has closed a new ¥400 million funding round, with XVC and Sequoia China joining as new investors and existing backers including Tencent increasing their stakes.
  • Kunwei abandoned the high-frequency ultrasound approach and instead uses low-frequency ultrasound combined with AI algorithms to achieve high-resolution, real-time brain imaging through the skull.
  • Its device can capture blood flow dynamics in the midbrain nuclei, lateral ventricles, and fine blood vessels at millisecond resolution.
  • Kunwei has already booked tens of millions of yuan in orders and plans to offer both hardware and its kOS software platform, positioning itself as brain-science infrastructure.
  • The company has a team of more than 200 people, with R&D staff making up over half and dozens focused on fundamental research in acoustic spatial intelligence.

PHYSIX OBSERVATION

Kunwei uses low frequency plus AI to sidestep the traditional ultrasound transcranial challenge, turning its device into a data gateway for brain science, with the ambition of becoming the underlying platform for brain-computer interfaces and NeuroAI. With funding in place, the key question is whether kOS can attract enough labs and companies to form an ecosystem.
