Liu Qiangdong climbs into the top 10 this year following the successful Nasdaq listing in May of his Chinese online shopping firm, JD.com, where he is chairman and CEO. Liu's first business was a restaurant he operated as a college senior, using money he made from computer programming and tutoring students. Although the restaurant business failed, Liu started building the predecessor to JD.com in Beijing in 1998. In 2004 he launched his first online retail website. JD.com was China's largest online direct sales company in terms of transaction volume in 2013, with revenues of $11.5 billion and market share in China of nearly 47%.
