Who he is

Joseph Tsai is co-founder and chairman of Alibaba Group [1]. He has served on the Alibaba board since the company's inception in 1999, which places him among the people who have been part of its governance from the first day [1]. His career before that ran through law and through investment work, and those two strands explain the posts he has held inside the company.

Education

He received a BA from Yale College in 1986 [1] and a JD from Yale Law School in 1990 [1]. A JD is the standard professional law degree in the United States: a graduate qualification taken after a bachelor's degree, usually beginning with required courses in areas such as contracts, civil procedure and legal writing, followed by specialised electives. A broad undergraduate degree followed by a focused legal training is a common route into American legal practice, and it means that a lawyer arrives in the profession knowing how to read rules closely and argue about their application.

Law and investment career

He worked early on as a tax-law associate at Sullivan & Cromwell LLP in New York [1]. Tax practice is a specialised branch of law: it deals with how statutes, regulations and treaties allocate tax obligations among people and companies, and cross-border transactions often turn on how two national systems interact. Associates at large firms typically spend their time on research, drafting and reviewing documents under a partner's supervision, which gives them a close view of how transactions are put together and where the risks sit.

He later worked on Asian investments for Investor AB, the Swedish firm linked to the Wallenberg family [1]. Investment companies of that kind hold and manage stakes in other businesses; working on a regional portfolio means assessing individual companies, following markets and looking after those holdings over time. That work sits closer to business decisions than tax advice does, and it is the part of his background that leads naturally towards building and running a company.

Roles at Alibaba

He has served on the Alibaba board since its inception in 1999 [1]. Earlier Alibaba roles listed for him are executive vice chairman, chief financial officer and head of strategic investments [1]. A chief financial officer is the senior executive responsible for a company's accounts, its financial reporting, its capital, and its relationships with investors and lenders. The head of strategic investments looks after the stakes a company takes in other businesses, from minority holdings to longer-term partnerships. An executive vice chairman sits between the board and the operating management, typically working on strategy and on external relationships.

Taken together, those three posts cover the money, the deal-making and the strategy of a growing company. Someone who has held all of them has seen the business from several angles rather than from a single function.

Current position

His current title is co-founder and chairman of Alibaba Group [1]. The chairman's job is to lead the board — setting its agenda, running its meetings and speaking for it — while day-to-day executive duties sit with the chief executive and the management team. A chairman who has previously handled finance and investment brings an operating background into a governance role, and that combination is what his public record at the company shows [1].
