Jet.com burst onto the e-commerce scene in 2015 with a bold mission: to make online shopping smarter, cheaper, and more rewarding for value-conscious consumers. Founded by serial entrepreneur Marc Lore—fresh off the sale of Diapers.com to Amazon—the startup aimed to disrupt Amazon's dominance by introducing a revolutionary pricing model that rewarded shoppers for making economically efficient choices. Its signature innovation, the 'Smart Cart,' dynamically adjusted prices in real time based on user behavior, encouraging larger orders and cost-saving actions like waiving returns or paying with a debit card. Initially launched as a $50-a-year membership service akin to Costco, Jet quickly pivoted to remove the fee after realizing its technology could drive savings organically. The strategy worked, and within a year, Jet had attracted over 3.6 million customers and was growing faster than Amazon at the time. Despite its early success, Jet faced immense pressure in the cutthroat world of e-commerce, where growth often came at the expense of profitability. In 2016, Walmart acquired Jet for $3.3 billion—not to eliminate competition, but to gain access to its tech, talent, and strategic vision. Lore became the head of Walmart’s U.S. e-commerce division, where he spearheaded major improvements, including free two-day shipping and enhanced grocery delivery services. Over time, Jet’s unique brand identity faded as its features were gradually integrated into Walmart.com. By mid-2020, Jet.com was officially shut down, marking the end of the standalone platform but not its influence. Jet’s legacy lives on in Walmart’s transformed digital infrastructure and competitive stance against Amazon. The story of Jet.com underscores the importance of innovation, adaptability, and strategic acquisition in the fast-moving world of e-commerce. It also highlights how disruptive ideas can reshape entire industries—even if the original company doesn’t survive the journey.
