When Jack Ma founded the Alibaba Group in 1999, he had 500,000 yuan in his hand and the support of 17 friends. Now eight years later, Alibaba has become China’s largest online commerce company, earning a profit of 1.36 billion yuan in 2006.
But when asked what makes him proud, Ma surprised many people by putting his employees way ahead of his legendary e-commerce websites.
“I feel most proud of my team, and the least of the websites,” Ma said. “The secret of my success is relying on team work and having a sense of mission（使命）”
Ma made the remarks on the eve of Alibaba Group’s shares becoming available for trade on the Hong Kong Stock Exchange last Tuesday. On the first day of trading, the shares more than doubled in value.
Eight years ago, when Ma created Alibaba, he envisioned（预想）that the Internet would change people’s lives. But the former English teacher knew little about computer science. “So I decided to hire someone who knows technology and respected his decisions,” he said.
Ma said he trusts his employees fully as long as they are diligent and have a sense of purpose.
“When people apply to work for Alibaba, I talk with them for two hours to lower their expectations. I tell the applicants not to expect a pay raise or promotion, but to prepare to work long hours and to be criticized by the boss, “ Ma said.
But Ma is not a rigid（严厉的）boss. He is like a friend in the eyes of most his employees. Unlike traditional companies where most of the people do just what their boss asks, he treats them as partners and encourages them to present their own ideas.
“I have confidence in the online commercial service in China and encourage my more than 4,000 staff to remain united to make Alibaba the biggest ecommerce supplier for China, Asia and even the world,” said Ma.
He promotes company values of honesty, passion and teamwork. Those who don’t accept these principals will find it hard to work there, no matter how talented they are.
“I have seen many who are more clever and hardworking than my team and me,” Ma said. But “we have a loyal team which has stayed on the same course, no wavering（摇摆）.” And Ma pursuing his dream is the magnet（磁铁）that draws talents in.
