This week on Generating Alpha, I’m joined by Marty Chavez — computer scientist, Wall Street innovator, and one of the most influential technologists in modern finance. Trained as a physicist and doctor before pivoting to technology and markets, Marty has spent his career redefining how data, software, and capital intersect.

Best known for his time at Goldman Sachs, Marty served as CIO, CFO, and co-head of its Securities Division — pioneering the firm’s digital transformation and helping to build one of the most advanced trading architectures in the world. Today, he serves as Vice Chairman of Sixth Street and sits on the board of Alphabet, continuing to shape the future of finance and technology from both sides of the table.

In this conversation, we explore Marty’s path from early interest in coding to leadership on Wall Street, his experience applying machine learning in the ’90s, and the biggest lessons he’s learned about risk, systems, and human behavior. He shares thoughts on AI’s evolving role in finance, the importance of communication, and why being an outsider can be a superpower.

Marty’s perspective is invaluable because it bridges disciplines — offering rare clarity on how technology is reshaping markets, institutions, and the people who drive them.
