Zhang Yiming
Co-founder 2016Background
Zhang Yiming studied software engineering at Nankai University, where he developed the technical foundation that later shaped ByteDance's product culture. Before founding ByteDance, he worked at Microsoft and several Chinese internet startups, gaining experience in search, travel, content systems, and large-scale consumer software. Those roles exposed him to a recurring weakness in early internet media: distribution was often controlled by editors, portals, search boxes, or user subscriptions rather than real-time behavioral prediction. Zhang's insight was that machine learning could become the organizing layer for information. Toutiao, ByteDance's early news aggregation product, became the proof point. It personalized content without relying primarily on an user's social graph. That experience became the intellectual and technical foundation for Douyin and TikTok, where the same algorithmic logic was applied to mobile video, music, and creator culture.
