The majority of KoGuan's fortune is derived from his stake in Tesla, the electric carmaker. KoGuan owned about 22.6 million shares of Tesla Inc. and 1.23 million options as of Aug. 27, 2022, according to bank records reviewed by Bloomberg News.

He also owns a stake in SHI International, a closely held provider of technology products and services. SHI International had more than $12 billion of revenue in 2021, according to the company's website. KoGuan owns 40% of the company, according to a company spokesperson.


Family: Unknown, No children

KoGuan was born in Indonesia, the son of Chinese parents. He later moved to the U.S. and received degrees in international affairs from Columbia University and law from New York Law School.

In 1989, he bought steeply discounted assets from a bankrupt software supplier called Lautek that was based in Somerset, New Jersey. The assets, which came from a Lautek division called Software House, became the basis for SHI International. KoGuan ran the company with his then-wife, Thai Lee, who was the first Korean-American woman to enter Harvard Business School. The two had married in 1989 and divorced in 2002.

By 2000, KoGuan had stepped away from the day-to-day operations of SHI, which at that point had annual revenue in excess of $1 billion. He remains the company's chairman and holds a 40% stake. Lee, who is chief executive officer, controls the remainder. She's said publicly that SHI never has sold shares to outsiders or taken on debt. It had more than $12 billion in revenue in 2021.

Little is known about KoGuan's life over the past two decades. In the late aughts he was involved in the development of luxury hotels in Shanghai. By then he'd also begun a years-long series of donations to a handful of Chinese universities including Peking University and Shanghai Jiao Tong University. Via his charitable foundation, he's written extensively about the need to preserve Chinese culture and warned that China wouldn't be best served by turning into a Western-style market economy.

In about 2018, Koguan made investments is several stocks including Baidu and Nvidia before selling off most holdings and concentrating on his investment in Tesla, the electric vehicle maker. By 2021, he'd become the company's third-largest known individual shareholder.
