Jack Ma Yun (born 10 September 1964) is a Chinese business magnate, investor, and philanthropist. He is the co-founder and former executive chairman of Alibaba Group, a multinational technology conglomerate. A former English teacher, he founded Alibaba in 1999, which became one of the world's largest e-commerce businesses. He is a charismatic leader who symbolized China's tech rise. In 2020, after criticizing Chinese financial regulators, Ma disappeared from public view for months, and the IPO of his fintech company Ant Group was suspended. He has since kept a low profile, stepping back from his business roles to focus on philanthropy and teaching.
