Zhang Yiming
Zhang Yiming is the founder of ByteDance, the Beijing-founded technology giant behind TikTok, Douyin, Toutiao, and a suite of AI-driven content platforms that have collectively reshaped how digital advertising reaches consumers at scale. His most consequential contribution to the AdTech ecosystem is the development and deployment of a recommendation engine so precise that it redefined performance expectations for social and video advertising — forcing incumbents like Meta and Google to accelerate their own algorithmic ad-targeting capabilities. TikTok's advertising platform, built on ByteDance's core AI infrastructure, introduced a new paradigm of interest-graph targeting that operates independently of traditional identity signals, making it one of the most disruptive forces in programmatic and social advertising of the past decade.
