Ma Yun (জ্যাক মা), more commonly referred as Jack Ma, is a Chinese businessman and philanthropist. He is the founder of the Jack Ma Foundation, and co-founder of Alibaba Group and Yunfeng Capital. As of May 2025, Ma's net worth was estimated at US$27.2 billion.

After taking the gaokao three times, Ma earned a bachelor’s degree in English from Hangzhou Normal University in 1988 and was assigned as an English and international trade lecturer at Hangzhou Dianzi University. Interested in internet entrepreneurship since the 1980s, he founded his first business, Hangzhou Hope Translation Agency, in 1994. The following year, he created the agency’s website and then resigned from the university to establish Hangzhou Hope Computer Services Co., Ltd., one of China’s earliest internet startups, which operated an online yellow pages service for Chinese companies. In 1996, Ma’s company was acquired by China Telecommunications Corporation. Following an unsatisfactory collaboration, he left the company the next year and went on to develop websites for China’s Ministry of Foreign Trade and Economic Cooperation. In 1999, he co-founded Alibaba Group, initially as a business-to-business (B2B) e-commerce marketplace and later expanded into a multinational technology conglomerate.

Ma was born in Hangzhou, Zhejiang, on 10 September 1964, as Ma Yun. He became interested in learning the English language as a young boy and began practicing it with English-speaking visitors who frequented the Hangzhou International Hotel. At the age of 12, Ma bought a pocket radio and began listening to English radio stations frequently. For nine years, Ma rode 27 km (17 miles) on his bicycle every day to work as a tour guide of Hangzhou for foreigners in order to practice his English. He became pen pals with one of those foreigners, who nicknamed him "Jack" because he found it hard to pronounce his Chinese name. When Ma was 13 years old, he was forced to transfer to Hangzhou No. 8 Middle School as he kept getting in fights. In his primary school days, Ma struggled academically, and it took two years for him to gain acceptance at an ordinary Chinese high school, as he only got 31 points in mathematics on the Chinese high school entrance exam.

In 1980, while he was riding his bike to practice English with tourists, he met Ken Morley, who was traveling with his family with the Australia-China Friendship Society. Ken's son, David, became pen pals with Ma and kept in touch after the family left China. Years later, the Morleys hosted Ma in Australia, changing the course of his life completely. Ma later said: "Those 29 days in Newcastle were crucial in my life. Without those 29 days, I would never have been able to think the way I do today."

In 1982, at the age of 18, Ma failed the Chinese college entrance exam on his initial attempt, obtaining only 1 point in mathematics. Afterwards, he and his cousin applied to be waiters at a nearby hotel. His cousin was hired, but Ma was rejected on the grounds that he was "too skinny, too short, and in general, protruded a bad physical appearance that may have potentially ended up hurting the restaurant's image and possibly tarnishing its reputation."

According to Ma's autobiographical speech, after graduating from Hangzhou Normal University in 1988, Ma applied for 31 different odd entry-level jobs and was rejected for every single one. "I went for a job with the KFC; they said, 'you're no good'", Ma told interviewer Charlie Rose. "I even went to KFC when it came to my city. Twenty-four people went for the job. Twenty-three were accepted. I was the only guy (rejected) ...". During this period, China was nearing the end of its first decade following Deng Xiaoping's economic reforms.

In 1994, Ma heard about the Internet and also started his first company, Hangzhou Haibo Translation Agency, an online Chinese translation agency. In early 1995, he travelled abroad to the United States on behalf of the Hangzhou municipal government with colleagues who had helped introduce him to the Internet. Although he found information related to beer from many countries, he was surprised to find none from China. He also tried to search for general information about China and again was surprised to find none. So he and his friend created an "ugly" website pertaining to information regarding Chinese beer. He launched the website at 9:40 am, and by 12:30 pm he had received emails from prospective Chinese investors wishing to know more about him and his website. This was when Ma realized that the Internet had something great to offer. In April 1995, Ma and his business partner He Yibing (a computer instructor), opened the first office for China Pages, and Ma started their second company. On 10 May 1995, the pair registered the domain chinapages.com in the United States. Within a span of three years, China Pages cleared approximately 5,000,000 RMB in profit which at the time was equivalent to US$642,998 (approximately $1.18 million today).

From 1999, Ma was executive chairman of Alibaba Group, which has remained one of China's most prominent high-technology holding companies in the two decades since it inception. It has nine major subsidiaries: Alibaba.com, Taobao Marketplace, Tmall, eTao, Alibaba Cloud Computing, Juhuasuan, 1688.com, AliExpress.com, and Alipay. At the annual general meeting of shareholders for Alibaba.com in May 2010, Ma announced Alibaba Group would begin in 2010 to earmark 0.3% of annual revenue to environmental protection, particularly on water- and air-quality improvement projects. Of the future of Alibaba, he has said, "our challenge is to help more people to make healthy money, 'sustainable money', money that is not only good for themselves but also good for the society. That's the transformation we are aiming to make."

Despite achieving massive entrepreneurial and investment success in the Chinese high-technology industry and the fact that Alibaba is a high-technology company, Ma was never a technical expert on computer technology nor did he possess the extensive breadth of executive managerial skills and background experience or depth of technical know-how that would have nonetheless otherwise qualified him to competently run a technology company or operate as an independent technology entrepreneur on his own. Even though Ma's formal educational background and extensive training was in English rather than in a technical subject, his dearth of technical expertise did not deter him from being able to competitively distinguish himself from the average Chinese technology mogul. As Ma with his distinct profile stands out among his entrepreneurial contemporaries throughout the Chinese high-technology industry, many of whom typically have a foundational background in computer engineering and science as part of their formal academic training and educational makeup. Instead, Ma parlayed his educational background to use in an entrepreneurial context by fashioning himself as a promoter, businessman, manager, administrator, and organizer who possessed the soft skills, emotional capacity, and personality with a knack for leading and employing specialists of expert ability from every conceivable technical domain. At a press conference in 2010, Ma made clear with regards to the lack of his technical expertise by revealing to the public that he had never written a line of computer code, nor had ever made one sale to a customer, and that he only acquired a personal computer to do business with for the first time at the age of 33.

News outlets noted a lack of public appearances from Ma between October 2020 and January 2021, coinciding with a regulatory crackdown on his businesses. The Financial Times reported that the disappearance may have been connected to a speech given at the annual People's Bank of China financial markets forum, in which Ma criticized China's regulators and banks. Ma described state banks as operating with a pawn shop mentality and criticized the Basel Accords as a "club for the elderly.": 50  Wired magazine suggests that Ma may have chosen to lay low during the stalled IPO period, influenced not only by government pressure but also by investors and employees within Alibaba who had lost millions due to the stalled IPO.

On 3 November 2020, the Shanghai Stock Exchange halted Ant Group's IPO. 50  According to Chinese bankers and officials, financial stability was the objective behind the intervention. Their scrutiny had extended beyond Ant Group to other major players in China’s technology sector, particularly the three dominant companies collectively known as BAT - Baidu, Alibaba, and Tencent. These three companies have faced allegations of leveraging their substantial market power to establish monopolistic positions, using their scale to suppress competition and hinder the growth of smaller rivals. Ant Group had sought to maintain a position as a technology company, although it was deriving approximately 90% of its revenue from financial services. 50  This position brought it into conflict with the People's Bank of China (PBOC), which since 2018 had sought to regulate Ant Group as a financial holding company.  50  After Ant Group filed for its IPO, PBOC had issued draft guidelines stating that it would regulate companies such as Ant Group as financial services companies, not tech companies.  51  During the IPO, financial regulators became even more concerned about Ant Group due to its high valuation as a tech company, increasing fears of a bubble.
