Internet and software company Kingsoft isn't as well known as smartphone giant Xiaomi, but both Chinese companies count entrepreneur Lei Jun as their controlling shareholder and enjoy close relations as a result.
Lei spent much of his early career at Kingsoft, where he started working as an engineer in 1992. He relinquished his role as the comapny's CEO in 2007 after taking the company public on the Hong Kong Stock Exchange.
Having achieved financial freedom, Lei left Kingsoft and went on to start Xiaomi in 2010.
Today, he is the chairman and single largest shareholder of Kingsoft.
