Every product leader wrestles with the same tradeoff: move fast and risk breaking things, or move slow and risk irrelevance. But what if the real accelerator wasn’t cutting corners—it was systematizing experimentation? In this episode, Hannah Clark sits down with Jean Castanon, VP of Digital Product at American Express, to explore how his team quadrupled their testing velocity in a year, redefined what “success” in experiments really means, and built a referral program that became Amex’s second-largest global acquisition channel.

Jean brings over a decade of experience at Amex across strategy, marketing, and digital, and he shares how his team balances speed, scale, and sustainability in product strategy. From building experimentation muscle to future-proofing digital storefronts, this conversation is packed with lessons for product leaders at every stage.
