John Willett is the Co-Founder and Chief Operating Officer of Rogo, one of the fastest-growing AI companies in global finance, used by leading institutions including Lazard, Jefferies, Rothschild & Co, Moelis and Nomura. Rogo has raised more than $300 million from investors including Kleiner Perkins, Sequoia, Thrive and Khosla, was valued at $2 billion in 2026, and John now leads its expansion across Europe and APAC.

In his first in-depth interview ever, John joins Vidit to tell the story behind Rogo and the person behind the company. He reflects on growing up in Connecticut in a family of engineers, being academically far ahead of his peers, meeting co-founder Gabe Stengel at Princeton, and experimenting with AI for finance years before ChatGPT made the category obvious.

John shares how early investor Kevin Ryan convinced them to quit investment banking and go all in, why Rogo spent its first two years with little external validation, and how ChatGPT changed enterprise demand almost overnight. He also explains how Lazard became the first major customer, what it took to earn the trust of global banks, and how Rogo evolved from an early product into a platform tackling some of finance’s most complex workflows.

They also unpack John and Gabe’s co-founder dynamic, why Gabe became CEO, how Rogo recruits former bankers into operating roles, and what John has learned scaling the company from roughly 40 to 200 people while building out Europe and APAC.
