Ernestine Fu Mak began working at Alsop Louie Partners while still a Stanford undergraduate, becoming known as one of the youngest venture capitalists in Silicon Valley after meeting a partner at an event and going through six rounds of interviews to join the firm. She went on to earn a PhD studying how people interact with self-driving cars, started a nonprofit at 15 inspired by her sister's struggle with depression, and now pairs her investing work with teaching and public service projects at Stanford.
