Augusto Marietti, CEO and cofounder of Kong, has one of the most remarkable founder stories in Silicon Valley history. In this conversation with Martin Casado, Aghi shares how he went from a garage in Milan to building one of the world’s leading API infrastructure companies, surviving years of rejection, living in the U.S. on $1,000 a month, and raising his first $50K while sleeping on Travis Kalanick’s couch. They talk about the near-death moments that defined Kong’s journey, the seven-year grind before breakout success, and how APIs became the “assembly line of software.” Aghi also explains how Kong evolved into the backbone of modern API and AI connectivity, and why the coming wave of AI agents will make APIs more essential than ever.
