Augusto “Aghi” Marietti, Cofounder and CEO of @Kong, has one of the most remarkable founder stories in Silicon Valley, from starting out of a garage in Milan to sleeping on Travis Kalanick’s couch to building an AI unicorn.
We sat down with Aghi to discuss 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.
