Hillhouse and AGI have invested in a humanoid robot "joint"

A well - known company in Wuxi has secured new funding.

On July 3rd, Wuxi QuanZhiBo Technology Co., Ltd. (hereinafter referred to as "QuanZhiBo"), a provider of integrated joint module solutions for robots, announced the completion of its A++++ round of financing. The round was led by GL Ventures, with strategic industrial players Zhiyuan and Lingxinqiaoshou participating as follow - on investors.

It is understood that the funds from this round of financing will mainly be used for exploring cutting - edge technologies, expanding the product portfolio, and further enhancing intelligent manufacturing and delivery capabilities.

With the successful completion of this new round of financing, it means that QuanZhiBo has completed seven rounds of financing in a year and a half since 2025. The participation of GL Ventures, Photosynthetic Venture Capital, Shenzhen Investment Holdings, Beijing Robotics Industry Fund, Wuxi Venture Capital, Zhiyuan, Lingxinqiaoshou, Leju Robotics, Geely, and CRRC has given the company a shareholder background of "top - tier investment institutions + leading industrial players + state - owned capital".

"The entry of top - tier investment institutions such as GL Ventures and Photosynthetic Venture Capital is a high recognition of our technological strength and commercial value," said Chen Wankai, the founder and CEO of QuanZhiBo. State - owned capitals like Shenzhen Investment Holdings, Beijing Robotics Industry Fund, and Wuxi Venture Capital not only bring in funds but also represent the strategic support of local governments for the intelligent manufacturing industry chain. "Introducing industrial players such as Zhiyuan, Lingxinqiaoshou, Leju Robotics, Geely, and CRRC is to close the industrial loop of 'joint - dexterous hand - complete machine'."

The story of QuanZhiBo began three years ago.

Back in 2023, noticing the lack of mature and user - friendly joints in the market, Chen Wankai judged that there was huge development potential for integrated joints, which are the power core of humanoid robots. "Because integrated joints account for nearly 50% of the cost of the complete machine."

Behind this conclusion lies his rich experience in the robotics field. After graduating from Huazhong University of Science and Technology for his undergraduate studies and the University of Melbourne for his master's degree, Chen Wankai pursued his Ph.D. at Jilin University under the supervision of Professor Liu Chunbao. He has long been engaged in the R & D of complete - machine robots at the Ocean Information Technology Research Institute of China Electronics Technology Group and the Zhejiang Institute of Advanced Technology, Peking University.

It was during this process that he gained in - depth knowledge of robot servo joints and other components, and finally came up with the idea of starting a business. In June 2023, Chen Wankai, born in 1993, founded QuanZhiBo in Wuxi with his partners from the Zhejiang Institute of Advanced Technology, Peking University, and invited Liu Chunbao to serve as the company's chief scientist.

Recognizing Chen Wankai's previous work at the Ocean Information Technology Research Institute of China Electronics Technology Group, CEC Huikang, also part of China Electronics Technology Group, invested 3 million yuan as the seed - round investor of QuanZhiBo. Soon after its establishment, QuanZhiBo chose to set up its headquarters at the CEC Huikang Wuxi Internet of Things Industrial Base jointly built by CEC Huikang and the Wuxi Municipal Government.

By independently developing the core technologies of the entire industrial chain of joint modules, QuanZhiBo integrated the reducer, motor, sensor, and driver into one, optimizing the structure and reducing the weight while improving the power density and space utilization. It also signed the first contract for integrated joints with Leju Robotics.

In addition to independently developing the core technologies of the entire industrial chain of joint modules, the company also entered the supply chain of Leju Robotics in 2024 and received investment from the latter. With the popularity of humanoid robots such as Unitree Robotics, QuanZhiBo, whose strength has been recognized by well - known customers in the industry, has accelerated its financing pace with the boost of the market.

According to Chen Wankai, the company completed consecutive rounds of financing from A2 to A6 in 2025. The investors included Landai Technology, Wuxi Venture Capital, Wuxi New Investment, Leju Robotics, Innoangel Fund, Tianqi Capital, Photosynthetic Venture Capital, Xingqi Fund under Falcon Investment, Beijing Robotics Industry Development Investment Fund jointly managed by Beijing Guorui and Shoucheng Holdings, Shouxin Jin'an Fund under Shoucheng Holdings, Daohe Capital, and CRRC.

Supported by sufficient funds and in cooperation with listed companies, QuanZhiBo quickly achieved a transition from technological breakthroughs to mass delivery. The shipment volume of its integrated joints exceeded 100,000 units in 2025. These remarkable achievements also caught the eyes of Shenzhen Investment Holdings, Photosynthetic Venture Capital, Junshan Capital, Liangjiang Capital, Orient Fortune, and Junxi Capital in April 2026.

After raising over 100 million yuan from these investors, the company announced the completion of its A++++ round of financing in July 2026. The investors included GL Ventures, which has long been deeply involved in the technology and advanced manufacturing sectors, Zhiyuan, a leading player in embodied intelligence, and Lingxinqiaoshou, the global leader in the high - degree - of - freedom dexterous hand market.

As early as 2023, GL Ventures began to increase its investment in the robotics and embodied intelligence industry chain. Recognizing QuanZhiBo's technological strength and delivery capabilities, the investment institution finally decided to make a move, making it a key player in the upstream core components of the industry chain.

For Zhiyuan and Lingxinqiaoshou, the domestic joint enterprise QuanZhiBo is crucial in their industrial layout. According to Zhiyuan's plan, the goal for 2026 is to mass - produce tens of thousands of general - purpose embodied robots, which means they need domestic joint partners capable of handling large - scale orders.

As for Lingxinqiaoshou, it values the differentiated competitiveness brought by the "joint + dexterous hand" collaborative solution. In their view, the capital - level cooperation with QuanZhiBo enables the two parties to jointly launch a "joint + dexterous hand" package solution for complete - machine manufacturers, thereby lowering the development threshold for complete machines and ultimately forming a technological synergy barrier.

The completion of this new round of financing also marks the formation of a diversified shareholder structure of "top - tier investment institutions + leading industrial players + state - owned capital" for QuanZhiBo.

Industrial players enter strategically, with expected order value of hundreds of millions in 2026

To date, QuanZhiBo has independently developed three major technological routes of "planetary + harmonic + cycloidal".

As a result, we can see that the torque range of the company's integrated joint modules covers from 2 Nm to 400 Nm, which can fully adapt to various application scenarios such as humanoid robots, quadruped robots, exoskeletons, and collaborative arms.

Data shows that planetary reducers are suitable for scenarios such as robot legs and hips, which require high load - bearing capacity and impact resistance; harmonic reducers are suitable for parts such as robot arms and wrists, which have extremely high requirements for precision and space. The cycloidal reducers, which have both high load - bearing capacity and a certain degree of precision, can meet the differentiated needs of customers.

The reason for choosing to cover all three types of reducers stems from their goal of "universal platform + scenario - specific". "Through modular design, we aim to lower the development threshold for complete - machine customers, allowing them to select products in a one - stop manner from QuanZhiBo's standardized product portfolio," Chen Wankai added.

More importantly, the company's strategy has been successfully recognized by the market. In the first half of 2026, the cumulative shipment volume of their integrated joint modules exceeded 120,000 units, with more than 60,000 units shipped in June alone. Currently, they have many well - known customers such as Leju Robotics, Songyan Power, and Xinghaitu. According to Chen Wankai, QuanZhiBo's annual orders exceeded 150 million yuan in 2025, and it is expected that the order value will reach hundreds of millions in 2026.

Facing large - scale orders, mass production and delivery, as well as technological pre - research, have become the company's current focus.

In April 2026, QuanZhiBo's precision joint production base in Wuxi was officially put into operation, with an expected annual production capacity of up to one million units. The production line, with an automation rate of over 85%, can produce one joint module in just 90 seconds. The one - time qualification rate of the products is stably above 96%, and the product yield rate remains above 98%.

In addition to being rooted in Wuxi, the company also plans to increase its investment in Beijing, Shenzhen, and Chongqing, which are also rich in industrial resources. Specifically, they will connect with top - notch scientific research resources and cutting - edge embodied intelligence technologies in Beijing and Shenzhen to accelerate commercialization, and achieve large - scale high - end manufacturing and ensure stable delivery and cost control in Chongqing.

According to QuanZhiBo's plan, they will cooperate with upstream core component suppliers, downstream complete - machine manufacturers, and scientific research institutions to build an open platform for embodied intelligent joint modules, and output standardized communication protocols, mechanical interfaces, and testing specifications, aiming to become an infrastructure - level supplier in the robotics industry.

"We will focus on the R & D of next - generation hollow - designed joints, the application of new materials, and products with higher torque density, and launch more than five new products covering multiple scenarios within the next year," Chen Wankai said directly. QuanZhiBo's goal is to define the standards for robot joints and enable Chinese robots to use the best and most cost - effective "Chinese joints".
