Walmart spent 3.3 billion dollars on a startup, then let it die on purpose

By 2015, Walmart's online sales sat at roughly 14 billion dollars. Amazon's retail business alone was doing 99 billion. Walmart had been trying to build its way out of that gap for years, and the gap kept getting wider. So in 2016, the company tried something different. It bought a two-year-old startup called Jet.com for 3.3 billion dollars, the largest e-commerce acquisition in US history at the time.

Four years later, Walmart shut Jet.com down completely and called the whole thing a success.

What Walmart actually paid for

Jet.com wasn't particularly profitable, and its headline feature, a dynamic pricing tool called Smart Cart that adjusted prices as customers added items to their basket, never became the industry standard some expected. What Walmart really bought was Marc Lore.

Lore had already built and sold one e-commerce company, Diapers.com's parent Quidsi, to Amazon for around 545 million dollars. Keeping him in charge after the acquisition was a condition Lore set before he'd agree to the deal at all, not a courtesy, and Walmart accepted it. He came in as CEO of Walmart's entire US e-commerce operation, not just as a division head running his old startup inside a bigger company.

The strategy that looked strange at the time

Walmart let Jet.com keep operating as a separate brand for years after the acquisition, running alongside Walmart.com, competing for some of the same customers. To outside observers this looked like poor integration, two competing websites owned by the same parent company, sending mixed signals.

What was actually happening underneath was different. Lore and his team spent those years quietly rebuilding Walmart's e-commerce technology, culture and pace of decision-making from the inside, using Jet as a base of operations while the harder, less visible work of modernising the core Walmart brand happened in parallel.

Then the brand that started it all got switched off

In May 2020, Walmart announced it was discontinuing Jet.com entirely. Most of the team moved permanently onto Walmart-branded roles. CEO Doug McMillon didn't describe this as a retreat. He credited the original Jet acquisition for jump-starting years of progress that the company had struggled to make on its own. That same year, Walmart's e-commerce sales grew 37 percent, then surged 74 percent in the first pandemic quarter alone, as customers who'd never shopped online with Walmart before started doing exactly that.

The startup Walmart bought didn't survive. The transformation it was bought to trigger did.

Why this worked when GM's automation bet didn't

A few decades earlier in this series, GM faced a competitive threat it couldn't out-build internally and responded by spending somewhere between 40 and 90 billion dollars on robots and automated factories. That spending never fixed the underlying problem, because the gap with Japanese manufacturers was about management and culture, not machines.

Walmart faced a similar kind of existential gap against Amazon and chose almost the opposite instrument. Instead of buying machines, it spent a fraction of what GM lost on automation to buy people, leadership and an entirely different operating culture, then gave that culture real authority inside the parent company rather than boxing it into a side project. GM tried to purchase its way out of a culture problem using capital equipment. Walmart tried to purchase its way out of a culture problem using an actual culture, and let the original brand disappear once it had done its job.

What this decade actually teaches

When you acquire a company specifically to change how your own organisation thinks and moves, the acquired brand is disposable. The people, the habits and the pace they bring with them are the entire point. Walmart never needed Jet.com to survive as a business. It needed Jet.com's founder and team to survive as an operating philosophy inside Walmart, and by the time the original website closed, that philosophy no longer needed a separate name to keep running.
