Patrick McKenzie (patio11) is joined by Emily Sands, Head of Information at Stripe, to discuss how they leverage AI to process over $1.4 trillion annually, while navigating the complex web of merchants, banks, and payment rails that facilitate online commerce. Patrick and Emily cover how Stripe’s layered stack of AI combats sophisticated card testing attacks, recovers billions in once-lost revenue through intelligent retry strategies, and enables new businesses to compete with established players through powerful network effects. They also talk about the meteoric rise of AI companies, and how agent-assisted commerce is beginning to transform online shopping through controlled financial rails.
