What does a degree in Rhetoric do for your career? (Plus How Retail Media’s Data Problem Is Holding the Industry Back) with Stephen Howard-Sarin
What does it actually take to build a retail media business from the ground up, not once, but across some of the biggest names in the industry? Master Orator Stephen Howard-Sarin has done it at eBay, Walmart, Instacart, and Criteo, and he joins Austin and Elizabeth to share what he has learned along the way.
From dirty product catalogs hiding in plain sight to the buy-side’s trade spend hangover slowing down scale, Stephen pulls no punches on where retail media still gets it wrong. He also makes the case for why fragmentation is a mental limit more than a real one, and why an ounce of patience might be worth more than all the AI in the room.
