Jack Ma: The founder of Alibaba
The Chinese billionaire set up his online shopping site in 1999. When Alibaba first started, Jack Ma and his team were working out of a small flat in Hangzhou. The BBC's Michael Bristow has been hearing from Duncan Clark, who first worked with the internet entrepreneur in those early days.
