Born in San Jose, California, in 1992, Andy Fang is a self-made tech billionaire and one of the co-founders of DoorDash, the dominant food delivery service in the United States. His background is rooted in the technological heartland of the San Francisco Bay Area; he is the child of Taiwanese immigrants and excelled academically at the prestigious Harker School.

Fang attended Stanford University, graduating with a Bachelor of Science (B.S.) degree in Computer Science in 2014. His time at Stanford was foundational: he was a section leader for a computer science course, demonstrating his teaching and leadership skills, and he was roommates with his future co-founder, Stanley Tang. The core idea for DoorDash emerged in 2013 as a class project for a joint Engineering and Business school course, born from the simple observation that local small businesses had not yet solved the logistical puzzle of food delivery.

Andy Fang co-founded DoorDash in February 2013 while still an undergraduate student at Stanford, initially naming the service PaloAltoDelivery.com. His role from the inception was crucial: he became the company’s Chief Technology Officer (CTO), responsible for designing and scaling the complex logistical software—the 'operating system'—that powers the three-sided marketplace (merchants, customers, and delivery drivers, or 'Dashers').

In the early days, the founders famously made deliveries themselves, giving them first-hand experience with the logistical challenges. Under Fang’s technological leadership, DoorDash scaled rapidly, using data-driven insights to optimize routing, order flow, and customer experience. The company successfully executed its IPO in December 2020, an event that immediately secured Fang’s billionaire status based on his substantial equity stake (approximately 4% of the company). After stepping away from the CTO role, he moved to Head of Consumer Engineering, continuing to guide the platform’s product vision and development.

Andy Fang’s primary social impact is the creation of a massive, flexible economic opportunity for thousands of independent workers (Dashers) and the enabling of delivery services for countless small businesses. DoorDash’s platform fundamentally changed the economic model of local commerce in the US, providing a vital service during the pandemic and beyond.

His personal philanthropy is often directed toward educational institutions and supporting entrepreneurship, reflecting his own path through Stanford and the Bay Area startup ecosystem. As a high-profile Taiwanese-American technology leader, his success is an inspiring example for minority entrepreneurs in the STEM fields. His commitment to building essential software infrastructure translates into a long-term economic and social contribution to urban and suburban communities.

Andy Fang maintains the casual, hyper-efficient style of a young, successful Bay Area tech executive. His attire is functional, comfortable, and discreet—favoring high-quality hoodies, casual shirts, and designer sneakers over formal suits. His look emphasizes innovation and productivity over fashion.

His lifestyle is characterized by youth, significant wealth, and a continued focus on technology and engineering, reflected in his shift to Head of Consumer Engineering. His high-profile marriage to professional tennis player Carol Zhao connects his life to the world of international sport and high-end leisure (their wedding took place in Florence, Italy). His luxury is the freedom to continuously iterate and refine the complex algorithms that power the DoorDash platform, a life lived at the intersection of logistics, data, and immense personal wealth.
