Recorded live at Shoptalk Spring, this episode of the AiR Podcast tackles the shift from AI experimentation to real-world accountability. Mark Williamson, AVP of Retail Media at Costco Wholesale, joins Kimberly Morgan, CEO of The Fashion Tech Exec and a Top AI Leader, to discuss why Costco is building its technology ecosystem "from the studs up." The Path of Most Resistance While many retailers opt for "plug-and-play" black-box solutions, Williamson explains why Costco is intentionally choosing a more complex, transparent path. By keeping member data behind its own firewall and inviting partners to work natively inside the Costco data cloud, the company eliminates signal loss while upholding its core code of ethics: respect for the member and respect for the supplier. No AI Strategy Without a Data Strategy The conversation centers on the necessity of a modular, interoperable tech stack. Morgan and Williamson explore how this foundation prepares Costco for the era of agentic commerce. By organizing data properly today, Costco ensures it can provide relevant value wherever members shop in the future—whether via an LLM, a search engine, or the warehouse floor.
