Evan Spiegel, Snap
APR 12, 2026
Evan Spiegel, Snap
Evan Spiegel is the co-founder and CEO of Snap Inc., the company behind Snapchat. At Stanford, he enrolled in the product design program. In 2011, in a class project, he and two classmates — Reggie Brown and Bobby Murphy — sketched out the idea for an app where photos disappeared. The insight was counterintuitive: in an era when everyone was obsessed with permanence and curation online, ephemerality might be the point. They built it. Spiegel dropped out before graduation to run it full time. What followed was one of the most turbulent ascents in Silicon Valley history. Facebook tried to buy Snapchat in 2013 for $3 billion in cash. Spiegel, 23 years old, said no. The decision was mocked at the time and later vindicated. Snap went public in March 2017 at a $24 billion valuation, making Spiegel — still in his mid-twenties — one of the youngest self-made billionaires in history. Spiegel has always argued that Snap is a camera company — that the camera is the starting point for how the next generation communicates, not a feature, but the interface itself. Snapchat pioneered Stories, a format that Instagram, Facebook, WhatsApp, and YouTube all copied within years. It pioneered augmented reality filters at consumer scale. It built a maps product that shows where your friends are in real time. Every one of those ideas was imitated. Now he's making his biggest bet yet. Snap's sixth-generation Spectacles are AR glasses — a genuine attempt to build the successor to the smartphone. They overlay digital information onto the real world in real time. Spiegel believes the camera on your face will eventually replace the screen in your pocket. He and his wife Miranda Kerr run the Spiegel Family Fund, focused on arts, education, and human rights. In 2022 alone, he gave $20 million to a scholarship program in Stockton and wiped out the student debt of an entire graduating class at Otis College of Art and Design.

Tony Xu, DoorDash
MAR 29, 2026
Tony Xu, DoorDash
Tony Xu is the co-founder and CEO of DoorDash, the largest food delivery platform in the United States. Before he was a tech executive, he was a dishwasher. Xu was born in Nanjing, China, and immigrated to the U.S. at age four with parents who arrived with $200 in the bank. His mother had been a licensed doctor in China. In America, she waited tables at a Chinese restaurant in Illinois. Xu worked beside her, washing dishes. That experience became the animating idea behind everything he built. At Stanford, he and three classmates noticed that restaurants in Palo Alto had no good way to handle delivery. They built a basic website, called restaurants, and started driving orders themselves — skipping class to fulfill them. That crude experiment became DoorDash. They went through Y Combinator in 2013 with $120,000 in seed funding and a product that barely existed. What followed was a decade of improbable dominance. DoorDash entered a market that Grubhub had largely defined, absorbed punishing losses to win share city by city, and eventually surpassed every rival in the U.S. In December 2020, the company went public on the NYSE at a $32 billion valuation, making Xu a billionaire at 36. In 2022, DoorDash acquired the Finnish delivery platform Wolt for $8.1 billion, expanding the business from four countries to more than two dozen overnight. Xu has always insisted DoorDash is a logistics company, not a food app — a platform for local commerce that starts with restaurants but doesn't end there.
