Alibaba chairman Jack Ma is due to step down from the e-commerce giant on Tuesday, marking the end of an era for the firm.
He co-founded Alibaba in 1999 and it has become one of the world’s biggest internet firms.
Mr Ma’s success and colourful style has made him one of China’s most recognisable businessmen.
Daniel Zhang, currently Alibaba’s chief executive, will replace him as executive chairman.
The company is now valued at $480bn (£389bn) and Mr Ma is China’s richest man, with a net worth of $38.6bn according to Forbes.
He is also the first founder among a generation of prominent Chinese internet entrepreneurs to step down from his company.
“I think it will be very hard to replace somebody like Jack Ma,” said Rebecca Fannin, author of a book on China’s technology titans.
“He is one of a kind. He is the Steve Jobs of China.”
Who is Jack Ma?
Born to a poor family in the eastern Chinese city of Hangzhou, Mr Ma began his career as an teacher.
He bought his first computer at the age of 33 and was surprised when no Chinese beers turned up in his first online search for “beer”.
With no background in computing, Mr Ma co-founded Alibaba in his apartment, having convinced a group of friends to invest in his online marketplace.
It was not the first time he had tried to get a start-up off the ground.
“Alibaba was his third attempt at a company, he had two trials before,” said Duncan Clark who has written a book about Mr Ma and is also chairman of investment consultancy BDA China.
“He saw the promise of the internet quite early on, but it took a while for him to have a vehicle.”
Over the years, Alibaba has grown from an online marketplace into an e-commerce giant with interests ranging from financial services to artificial intelligence.
It was originally set up as a trading platform for businesses, before expanding into consumer e-commerce in 2003 and later launching digital payment platform Alipay.
Lacking a background in technology and with no particular strength in finance, Mr Clark said charisma and strategic vision have been Mr Ma’s biggest assets.
“His charm is a big part of his leadership, his ability to convince people whether it’s customers, employees or critically shareholders.”
The author first met Mr Ma two decades ago and the entrepreneur spoke of making Alibaba one of the top 10 internet companies in the world within a decade.
“[It was] a sort of impossible ambition in a way but somehow he made people believe it,” Mr Clark said.
Mr Ma did turn his firm into an international heavyweight and its listing in New York set a record as the world’s biggest public stock offering .
Earlier this year, he argued in favour of the “996 system” where workers are expected to work 12 hour days, and a six-day week – a hotly debated topic in Chinese media.
The flamboyant businessman is also known for enjoying the limelight and featured at an Alibaba event in 2017 wearing a Michael Jackson-themed outfit.
What’s next for Mr Ma?
The 55-year-old is expected to focus on philanthropy and education after he steps down.
Mr Clark said he has gradually brought technology and finance experts into Alibaba and more recently, Mr Ma has been “consciously edging himself out”.
