Zunpai Communication Technology

Zunpai Communication Technology (Nanjing) Co., Ltd. was a semiconductor startup established in March 2021 with a focus on designing high-end wireless communication chips. The company was founded by Zhang Kun, a former researcher at Huawei's chip development unit, HiSilicon, who left the tech giant in 2019. The founding team was composed of experienced professionals from leading chip manufacturers like HiSilicon, Qualcomm, and Marvell. Zunpai's business model centered on the development and sale of application-specific semiconductors, providing full-range Wi-Fi router AP SoC chips and complete solutions for both home and enterprise clients. Its product pipeline was focused on Wi-Fi 6 chips and the company was also engaged in the research and development of next-generation Wi-Fi 7 technology.

The company attracted significant investment shortly after its inception, securing a seed round of nearly 100 million yuan in May 2021 and a Pre-A round that brought its total funding to over 300 million yuan within a year. Notable investors included Xiaomi Corporation, Gaorong Capital, Allin Capital, and Vision Knight Capital. This capital was intended to fuel company operations, research and development, and market expansion. However, the company's trajectory was abruptly halted by legal challenges. In August 2023, a Huawei subsidiary initiated legal action, accusing Zunpai of intellectual property theft. Investigations revealed that 40 technical points in Zunpai's designs had a similarity of over 90% to Huawei's confidential technology. This led to the arrest of 14 employees in December 2023 and the freezing of company assets. In July 2025, a Shanghai court sentenced founder Zhang Kun and other employees to prison for stealing trade secrets, effectively dissolving the company.
