34-Year-Old Chen Yusen Takes Over as DingTalk CEO: From Teenage Hacker to Alibaba's Youngest Business Unit Head

On June 11, 2026, Alibaba announced a management reshuffle at DingTalk, with Chen Hang (Wuzhao) stepping down as CEO and being succeeded by Chen Yusen, head of Alibaba Cloud's AI Agent product MuleRun. Born in 1992, Chen Yusen becomes Alibaba's youngest business unit CEO.

Background: A Tech Geek's Entrepreneurial Journey

Chen Yusen is a serial entrepreneur. After graduating from Zhejiang University at 22, he founded cybersecurity company Chaitin Tech. In 2019, at 27, he sold Chaitin Tech to Alibaba Cloud, achieving financial freedom. In 2021, he left Alibaba, forfeiting unvested equity, and founded "Jiaogeimao" and "Serval Tech." In 2025, he returned to Alibaba Cloud for internal entrepreneurship, leading the development of AI Agent product MuleRun.

Key Details: MuleRun and DingTalk's AI Transformation

MuleRun is positioned as an AI Agent marketplace, offering pay-as-you-go and on-demand pricing. Public data shows MuleRun serves users in 43 countries and regions, with 34% of users paying over $200 monthly. Paying users are active 2.6 days per week, completing an average of 13 end-to-end tasks per week. After Chen Yusen takes over, the development approach for DingTalk's enterprise-grade Agent application "Wukong" may be adjusted.

Reactions and Data

Alibaba's Partnership Committee previously criticized DingTalk's management style, stating it was "not what Alibaba culture should be."
In an interview, Chen Yusen said MuleRun's core assumption is that once large models gain programming capabilities, they can theoretically do everything humans can on a computer. The platform currently still relies on traditional applications, but future long-tail demands will be largely met.
In 2024, Chaitin Tech completed a spin-off funding round of over 1 billion yuan, with the founding team becoming the largest shareholder, paving the way for an independent IPO.

Impact

Chen Yusen's appointment marks an acceleration of DingTalk's strategy in the AI Agent field. As competition in enterprise-level large model applications intensifies, DingTalk needs new product methodologies. Chen Yusen's technical background and entrepreneurial experience may bring a more flexible and open AI ecosystem to DingTalk.
