More than anything, Austin brings the perspective of an operator who has built retail media businesses from the inside. Having worked alongside retailers, brands, agencies, and technology partners throughout the industry's evolution, he believes the best conversations go beyond headlines and buzzwords to uncover the decisions, lessons, and leadership moments that shape where the industry goes next.
Today, Austin serves as Vice President & General Manager of Dollar General Media Network, where he's helping redefine how one of America's largest retailers creates value for shoppers, supplier partners, and the business through an integrated approach to retail media and enterprise marketing.
