Seth Dallaire, Walmart

Seth Dallaire is responsible for a portfolio of businesses that complement Walmart’s traditional retail operations. As executive vice president and chief growth officer, Dallaire oversees the retailer’s global enterprise platforms that include the third-party Marketplace, which expands assortment in stores and online; the retail media businesses Walmart Connect and Sam’s Club MAP; Walmart Data Ventures, whose Scintilla data product serves suppliers; and the Walmart+ membership program.

Dallaire also oversees VIZIO, the TV maker Walmart acquired in late 2024. Asked during a recent conference why Walmart would buy a TV company, he noted that the retailer sells plenty of TVs — and that the real business is no longer about buying televisions wholesale and selling them in its retail stores. The real opportunity now comes after the sale, powered by the operating systems “behind the glass” that drive connected TV advertising.

Before taking on his current role, Dallaire served as Walmart U.S.’s chief growth officer from 2024 to 2026, where he helped scale newer businesses in media, membership, marketing and data. From 2021 to 2024, he was the company’s chief revenue officer, helping Walmart expand beyond retail sales and build the financial flexibility needed to fuel innovation.

Before joining Walmart, Dallaire was Instacart’s chief revenue officer, where he built its advertising business from the ground up and partnered with more than 2,500 brands. He also helped grow Amazon’s retail media business as vice president of global advertising sales and marketing, and previously led sales teams at Yahoo! and Microsoft.
