Shanghai Deyin Investment Holdings

Chen Dejun, the founder and chairman of STO Express, is the ultimate controller of Deyin Investment. His sister and STO co-founder Chen Xiaoying also holds a major ownership stake, and investment direction aligns closely with the family's existing logistics and operational interests.

Deyin was founded by Chen Dejun, who built STO into one of China's major private express carriers. Alibaba Group is a strategic investor in STO Express and its subsidiaries, and the Chen family's investment vehicle benefits from close ties to both Alibaba and the Cainiao Network logistics platform. This relationship shapes Deyin's deal flow and portfolio composition.

Deyin concentrates on growth-stage investments in logistics and supply-chain infrastructure, commercial and industrial real estate, and e-commerce ecosystem adjacencies. The portfolio includes operating warehouses and facilities for STO Express in the US and commercial real estate in Shanghai via its Junhui Real Estate subsidiary.

While Deyin's primary strategic partner is Alibaba Group, the firm's deep industry ties through the Shanghai Express Association and China Society of Logistics provide access to co-investment opportunities with other logistics operators and supply-chain platforms. Specific co-investment partners are not publicly disclosed.

The family wealth originated from STO Express, which Chen Dejun and his sister Chen Xiaoying co-founded in 1993. STO became one of China's first private express-delivery companies and scaled alongside the growth of Alibaba's e-commerce ecosystem, generating the capital base that now supports Deyin's diversified investment activities.
