Ep. 13 - Industrial Safety AI: Stopping Accidents Before They Happen 07.05.2026

Safety is usually treated as a lagging indicator where leaders only react after a claim is filed or an injury occurs. This reactive stance is a massive profit leak and an avoidable human cost that traditional safety walks can no longer manage in complex industrial environments. Vernon O'Donnell, CEO of Voxel, explains how computer vision and AI are flipping this script by identifying risks be...

Ep. 12 - Automating the Freezer: The Future of Cold Storage Ops 23.04.2026

Cold chain is one of those supply chain functions everyone relies on, yet few people really understand until something melts, spoils, or gets rejected at the dock. We sit down with Cindy Parker, Director of Operations at Americold, to unpack what modern cold chain logistics actually looks like and why it has shifted from “storage at temperature” into a true operations partner for food, grocery, ex...

Ep. 11 - People-Led Growth: The Invisible Magic of Tech with Vinod Bidarkoppa 09.04.2026

Retail doesn’t just use technology anymore, it runs on it, and that changes what leadership looks like at the highest level. We sit down with Vinod Bidarkoppa, Executive Vice President and Chief Technology Officer of Walmart International, to get a clear view of how modern omnichannel retail, supply chain systems, marketplace growth, and in-store operations connect through a single tech strategy....

Ep. 10 - Supply Chain Mastery: Lessons from Georgia Tech 26.03.2026

Supply chain leaders love to ask for “the model,” but the hardest part is figuring out what the real problem is in the first place. We sit down with Georgia Tech professor Benoit Montreuil, Executive Director of the Supply Chain and Logistics Institute, to unpack how his team works with major partners like Amazon, Home Depot, and UPS to tackle frontier logistics challenges with real data, real con...

Ep. 9 - Decision Advantage: Winning in a Volatile Market 12.03.2026

Volatility isn’t a phase to ride out, it’s the operating system of modern logistics. We sit down with Michael Zimmerman, partner at Kearney and veteran of Fortune 500 supply chains, to unpack how structural shocks from trade policy, weather, and geopolitics have rewritten the rules of planning, sourcing, and execution. The throughline is clear: decision advantage beats tool accumulation. We dig in...

Ep. 8 - Supply Chain Design: From Mainframes to AI Agents with Laurie Tuschen 26.02.2026

What if your supply chain could answer hard questions in minutes instead of days? We sit down with Laurie Tuschen, Head of Customer Strategy at Optilogic, to explore how modern design stacks blend optimization, simulation, and AI to deliver faster, smarter decisions without adding new buildings or bloated spreadsheets. From the early days of mainframes to sensitivity-at-scale tools, Laurie shows h...

Ep. 7 - Inside Modern POS Systems With Michael Leister 12.02.2026

Checkout isn’t a place anymore. It’s a strategy. We dive into how modern POS now spans mobile devices in the aisle, self-checkout, curbside pickup, and scan-and-go, and what that means for customer experience, associate workflows, and the bottom line. With guest Michael Leister, who helped deploy hundreds of thousands of devices across Walmart and Sam’s Club and later supported Amazon’s last mile,...

Ep. 6 - Fixing Freight Rates with Data Ownership | With Sam Tibbs 29.01.2026

What happens when a Navy nuclear power alum and finance PhD turns his focus to trucking? Sam Tibbs joins us to make a bold case: freight doesn’t have a tech problem, it has an incentive problem. He traces the unlikely route from teaching and data science to building the tools that exposed lane-level profit and drove the most-used variables in Sonar, then explains why today’s rate products miss the...

Ep. 5 - The Hidden Cost of EDI Chaos 25.12.2025

Orders don’t move without clean data. We go deep with Jonathan Kish, SVP at Orderful, to reveal why EDI still runs global retail, where it quietly breaks omnichannel performance, and how modern teams can turn a tangle of maps and testing into a fast, reliable growth engine. From empty shelves to OTIF deductions, the symptoms are familiar; the root causes live in outdated mapping, slow retailer tes...

Ep. 4 - Refund Rage: The Psychology Behind Return Policies 11.12.2025

Ever wonder why a “standard” return policy can feel so unfair at the counter? We unpack the psychology and operations behind returns with Dr. Travis Tokar, Professor of Supply Chain Management at TCU, and explore how loss aversion, fairness, and frontline interactions shape customer reactions far more than a PDF policy ever will. We walk through the five policy levers: money, exchange, time, scope...

Ep. 3 - Why Digitizing The Warehouse Now Cuts Cost, Risk, and Stockouts 27.11.2025

What if your warehouse could flex labor across sites on demand, cut safety risk, and feed cleaner data into your WMS—all without a massive retrofit? We sit down with Brian Nachtigall, VP & GM of Vaux at ArcBest, to unpack smart autonomy that blends autonomous forklifts with remote teleoperation for a fast, pragmatic path to automation. No gimmicks, no buzzword soup—just a clear look at how dee...

Ep. 2 - Stablecoin Meets Omnichannel 13.11.2025

Money should move as fast as your cart. We sit down with Garrett Harper, Head of Business Development at Squads Labs, to unpack how Stablecoin is quietly becoming the payment rail that matches modern retail speed: instant refunds, cheaper settlements, and programmable rewards that actually feel valuable. If “buy online, pick up in store” reset fulfillment, Stablecoin is poised to reset how cash fl...

Ep. 1 - Omnichannel Gets an AI Brain 30.10.2025

A single chat that fills your cart, schedules pickup, and optimizes delivery isn’t sci-fi anymore. We break down Walmart’s new partnership with OpenAI and show how turning conversation into checkout could reshape margins, loyalty, and the last mile—without asking shoppers to open an app. We start with what the integration actually does: ChatGPT pulls live Walmart prices, builds context-aware baske...
