River Map explores the deep sea — a "deep-sea Huawei" ambition of a startup in the angel round
# He Tu’s exploration of the sea, the “Deep Sea Huawei” ambition of a天使轮 company **Key event:** Gongzhi Ocean Company, founded by a team from Harbin Engineering University, completed nearly 100 million yuan in angel round financing. Its founder, Guo Chunyu, was referred to by investors as the “Deep Sea Huawei”. **Technical approach:** The company adopts a coupling propulsion scheme of “vibrating fins + pump jets”. Flexible vibrating fins are responsible for low-speed silent positioning operations, while vector pump jets handle high speed and precise control. This combination achieves full functionality with a single unit. **Key breakthroughs:** By coupling submarine propulsion with sonar sensing, the radiation noise was reduced to 86 decibels, sediment disturbance was lowered to 1/500 of traditional solutions, propulsion efficiency reached over 90%, and zero-radius rotation was achieved. **Market context:** The compound growth rate of the domestic underwater robotics market is expected to reach 46.93% from 2025 to 2030. The “15th Five-Year Plan” clearly aims to build a strong marine nation, driven by both policy opportunities and industry demand. **Industry assessment:** There is a physical contradiction between traditional propeller propulsion and sensor sensing. Low-noise bionic propulsion will become the standard for intelligent underwater platforms…
