Retail doesn’t stand still, and neither does Sam’s Club.
In this episode of The Speed of Culture, recorded live at CES in Las Vegas, Matt Britton sits down with Diana Marshall, EVP and chief experience officer at Sam’s Club.
Diana shares how Sam’s Club is building a human-led, tech-powered membership model, why experience is now the primary differentiator in retail, and how closed-loop data and AI-driven personalization are reshaping acquisition, loyalty, and retail media.
The conversation explores the shift from frictionless to effortless retail, the power of associate experience, and what the future of buying looks like in an AI-enabled world.
A 21-year Walmart veteran, Diana began her career as a replenishment trainee and has held leadership roles across merchandising, operations, and marketing before joining Sam’s Club nearly three years ago.
Her background spans supply chain, general merchandise, and enterprise innovation, giving her a rare end-to-end perspective on how large-scale retail operates. Today, she leads Sam’s Club’s experience transformation, building a human-centered, tech-powered model designed to differentiate the brand in a rapidly evolving membership economy.
Key takeaways:
[00:04:56] Experience as the Differentiator — Sam’s Club recently formalized its experience organization, a first within the Walmart enterprise. While price, assortment, and trust remain foundational, Diana explains that experience is where the brand can truly win. The vision: create effortless, personal experiences that bring joy and foster community. It’s a shift from competing on value alone to competing on how members feel across physical clubs, digital channels, and human interactions.
[00:07:04] You Can’t Build Member Experience Without Associate Experience — One of Diana’s biggest early insights: member experience cannot improve unless associate experience improves first. From onboarding to tools to leadership culture, Sam’s Club is investing in setting associates up for success. The logic is simple—empowered, supported employees create better human moments. In a tech-heavy era, the associate remains a competitive advantage.
[00:10:46] The Closed-Loop Advantage of Membership Data — Because Sam’s Club operates on a membership model, it has full closed-loop attribution across behavior, purchase, and engagement. Diana describes building unified data systems that power next-best-action engines and real-time personalization. With structured, centralized member data, AI becomes actionable allowing Sam’s Club to move from broad campaigns to highly contextual experiences at scale.
[00:18:29] Retail Media as an Experience Platform — Sam’s Club’s Member Access Platform isn’t positioned as just another retail media network. Diana describes it as a “retail experience network,” designed not just to serve ads but to improve member experience. With closed-loop measurement and personalization capabilities, MAP supports brand partners while also driving acquisition and loyalty turning media into a strategic growth engine.
