China’s Newest Tech Billionaire Made His Fortune From Developing Image Sensor Chips For Robotics

The trend of mainland Chinese tech companies flocking to list in Hong Kong shows no sign of abating. The latest to make its stock market debut is Gpixel Changchun Microelectronics, a developer of CMOS image sensors that enable robots to “see.” Shares of the company, headquartered in the Chinese industrial hub of Changchun, rose 144% since its listing on Friday, making founder and chairman Wang Xinyang a billionaire.

Wang, 46, is Gpixel’s largest shareholder with a 23% stake. Together with the 1.6% holding of his wife Zhang Yanxia, Gpixel’s chief operation officer, Wang is worth $1.3 billion based on Tuesday’s closing price of HK$97.5. Gpixel didn’t respond to a request for comment regarding Wang’s billionaire status.

Gpixel’s IPO raised HK$2.6 billion ($332.4 million), drawing cornerstone investors including Chinese private equity giants Hillhouse Investment and Boyu Capital, as well as early ByteDance backer Source Code Capital and Hong Kong-based Value Partners. Gpixel disclosed in its prospectus that it will use 76% of the IPO proceeds for R&D investments, including building a new R&D center in Hangzhou, and the rest to expand operations in Hong Kong, South Korea and Japan.

The company specializes in CMOS image sensors, which are chips that convert light into electrical signals to capture images, and are embedded in a range of electronic products from smartphones and cameras to X-ray machines and robots. Operating under a fabless model, Gpixel designs sensors that are mostly used for industrial applications, such as detecting defects in semiconductor manufacturing and robot navigation. They are also deployed in advanced cameras, such as those used for scientific research.

Citing a Frost & Sullivan report in its prospectus, the company said it is the world’s third-largest supplier of industrial image sensors in 2024 with a market share of 15.2%, after Japan’s Sony and Nasdaq-listed U.S. company Onsemi. Gpixel earns nearly 80% of its revenue from mainland China, with customers such as Changchun UP Optotech, a state-backed photoelectric company and the largest institutional investor of Gpixel; Hikrobot, an arm of Chinese surveillance product supplier Hikvision that makes autonomous mobile robots and industrial cameras; and Luster LightTech, a manufacturer of vision inspection equipment. It also sells image sensors to markets including Europe, Japan, Canada, South Korea and the U.S.

In 2025, Gpixel posted a 49% jump year-over-year in net profit to 293 million yuan ($43 million) on a 27% rise in revenue to 856.5 million yuan. The company attributed the surge to rising sales of sensors for industrial imaging applications, which accounts for 75% of revenue. During the period, nearly 24% of the sales came from sensors for scientific imaging applications such as fluorescence cameras, with the rest from professional cameras and medical imaging applications.

Wang studied applied electronics at Zhejiang University then went on to specialize in microelectronics at the University of Southampton in the U.K. before earning a Ph.D. in the subject from Delft University of Technology in the Netherlands. He returned home to set up Gpixel in 2012 after a stint at Belgium-based CMOS image sensor developer CMOSIS (since acquired by Austrian sensor maker Ams Osram). Since then, Gpixel has attracted pre-IPO investors including Hillhouse and Juyuan Xincheng, a fund backed by Chinese chip giant Semiconductor Manufacturing International Corp., as well as a number of government funds.

His wife, meanwhile, joined Gpixel in 2013 as marketing director and became chief operation officer in 2018. She earned a Ph.D. in applied science from Delft University of Technology, a master’s degree in electrical engineering from Concordia University in Canada and a bachelor’s degree in electronic engineering from Zhejiang University.

Wang is the latest Chinese billionaire to amass a fortune within the robotics supply chain. Other billionaires include Howard Huang, founder and chairman of Shenzhen-based Orbbec, which makes 3D vision cameras that enable robots to perceive depth like human eyes do.
