Doug McMillon: The Leader Quietly Turning Walmart Into a Tech Powerhouse

A few years ago, I was standing in a Walmart checkout line watching someone return a laptop, another customer pick up groceries ordered online, and an associate scan items with a handheld device that looked more “Silicon Valley” than “big-box retail.” That moment stuck with me. Walmart felt different—faster, smarter, more digital.

At the center of that transformation is Doug McMillon, Walmart’s CEO, and one of the most influential (yet often underappreciated) business leaders of our time.

In this post, we’ll break down who Doug McMillon is, how he thinks, why Walmart is increasingly being viewed as a technology and AI-driven company, and what business owners, leaders, and everyday professionals can learn from his approach.

Who Is Doug McMillon? (And Why He Matters)

Doug McMillon is not your typical Fortune 1 CEO.

• Started his career unloading trucks at a Walmart distribution center
• Became CEO in 2014
• Now leads the world’s largest retailer through massive digital disruption

Unlike leaders who inherit the corner office from the outside, McMillon grew up inside Walmart. That background shapes everything from how he treats employees to how he balances innovation with affordability.

Walmart is no longer just a retailer. It’s a tech and data company that happens to sell everything.
