Andy Fang (born 1992) is a Taiwanese-American billionaire and internet entrepreneur, recognized as a co-founder of the food delivery service DoorDash. By December 2020, his net worth was valued at approximately $2.2 billion according to Forbes.

Early life and education

Born in San Jose, California to parents who immigrated from Taiwan, Fang was raised in the San Francisco Bay Area. He completed his secondary education at the Harker School in 2010 before pursuing a Bachelor of Science degree in computer science at Stanford University. During his time at Stanford, Fang shared a dormitory with Stanley Tang, with whom he created a social calendar application, and he also became acquainted with Tony Xu through a combined engineering and business course.

Career

In 2013, while still enrolled at Stanford, Fang joined forces with Tang and Xu to launch DoorDash, an online platform specializing in food ordering and delivery. Originally called PaloAltoDelivery.com, the venture aimed to fulfill the demand for delivery services among small local businesses. In the early stages, the founders themselves handled deliveries. Fang held the position of chief technology officer (CTO) at DoorDash from May 2013 until February 2019.

The concept for DoorDash emerged from a collaborative project integrating engineering and business studies. The service rapidly grew beyond its initial geographic focus, culminating in a public offering in December 2020 that substantially increased Fang's wealth. As of March 2025, he owns roughly 4% of DoorDash's equity and oversees its consumer engineering team.

Personal life

On July 20, 2024, Fang wed Canadian professional tennis player Carol Zhao at the Belmond Villa San Michele located in Florence, Italy. Both are alumni of Stanford University.
