Teresa Heitsenrether joined JPMorgan Chase as a summer intern in 1987. Thirty-nine years later, she announced that she is stepping down at the end of 2026 as the executive who built one of the most advanced AI infrastructures in global banking.
What's notable is that she’s departing at the precise moment the bank is preparing to deploy what she spent three years constructing.
The announcement came in a memo from CEO Jamie Dimon and COO Jennifer Piepszak on July 1, 2026. "Teresa has played a pivotal role in building and transforming some of our most important institutional businesses and, most recently, in shaping the firmwide data and artificial intelligence strategy that is central to our future," they wrote.
