He retired earlier this week.He has driven Alibaba to become a $390 billion giant, which dominates China’s online retail market, stretches from logistics to social media, and has spawned a separate fintech empire around popular payment platform Alipay.Ma, a former English teacher, co-founded Alibaba in 1999 with 17 others and has become one of China’s richest people with a net worth of $36.6 billion, according to Forbes.Ma, 54, has no technical background. Alibaba was founded at a time when the industry was still dominated by state-owned firms and entrepreneurship was seen as a risky career path. It has since has grown to have more than 66,000 full-time employees and a market value of some $420 billion.Ma will give up the chairman role on September 10, 2019 and complete his current term on Alibaba’s board of directors following the company’s annual general meeting in 2020.

Here is the number one mistake that most startups commit, according to him.“I think the number one mistake that most of the startups make is say, “I don't have money’. If I have money I am going to solve this problem”,” he told CNBC-TV18 in an interview in 2015.Ma said lack of money is never the real problem for startups. Instead, it is the lack of people who have dreams and would die for the dreams. “It’s difficult to find the team who believe in the dream and work together and execute one (action) little-by-little every day,” he said.People who always have complaints or lot of excuses — “I don't have money, I don't have people, I don't have the technology” — are the ones who lose, according to him.Ma said human beings easily forget mistakes. “It’s always easy to forget about the terrible days. When things are going good, they always think that it will be better,” he said.
