Lei Jun

Known by many as the Steve Jobs of China, black-jeans-and-t-shirt-wearing Lei Jun co-founded fast-growing mobile phone maker Xiaomi in 2010 with his friend and fellow billionaire Lin Bin. Xiaomi has become hugely popular because its phones offer the high power of rivals at a much lower price. A serial entrepreneur, he also chairs gaming company Kingsoft. Its spinoff, Cheetah Mobile, which provides mobile application software, went public in New York in May 2014. Another company backed by Lei, Internet services supplier Xunlei, went public on the Nasdaq in June 2014. He also chairs U.S.-traded YY, a Chinese social site he co-founded. He sits on the board of Wuhan University, where he earned a BA in computer science in 1991.
