Zhang Yiming

Zhang Yiming founded ByteDance in 2012 with the revolutionary vision that machine learning algorithms could distribute information more efficiently and accurately than human editors, a philosophy that led him to develop the proprietary interest-graph recommendation engine that powers TikTok and Douyin, fundamentally altering the global digital media landscape.

Zhang Yiming, born in 1983 in Longyan, Fujian Province, China, is a Chinese software engineer and entrepreneur who founded ByteDance, the parent company of TikTok and Douyin. Zhang graduated from Nankai University in 2005 with a degree in microelectronics, but his true passion lay in software development and internet technologies. After working for a series of startups, including a travel search engine and a microblogging platform, Zhang became frustrated by the inefficiencies of human-edited content distribution and the rigid corporate structures that stifled innovation. In 2012, he founded ByteDance in Beijing, launching the news aggregation app Toutiao, which utilized machine learning to personalize news feeds. The success of Toutiao provided the data and capital necessary to launch Douyin in 2016 and TikTok in 2017, transforming ByteDance into the most valuable private technology company in the world. Zhang served as CEO until 2021, when he stepped down to focus on long-term strategy and artificial intelligence research, handing the CEO role to Liang Rubo. Zhang is known for his deep technical expertise, his rational, data-driven approach to management, and his vision of creating a globally connected, algorithmically curated information ecosystem. He remains the largest individual shareholder of ByteDance and continues to guide the company’s strategic direction in AI and global expansion.
