About Me

Leo KoGuan is founder and chairman of $15 billion (gross sales) IT provider SHI International, which his ex-wife Thai Lee, also a billionaire, runs as CEO. Leo, who once claimed to be Tesla's third largest individual shareholder, is now an Elon Musk critic and says he's sold a chunk of his shares. He posted on X in November that he was "no longer all-in-Tesla" and instead accumulating 3-month Treasury Bils. Born in Indonesia, Koguan received a master's degree from Columbia University and a law degree from New York Law School. He says his first investment was in Manhattan real estate, which he then sold to buy a software reseller, SHI's predecessor, for less than $1 million in 1989. At the start of the pandemic market chaos, he sold most of his stock holdings, including shares of Baidu and Nvidia, to buy long-term Tesla call options.
