The Mars Agency

The Mars Agency, recently rebranded as Mars United Commerce, is a global commerce marketing and shopper advertising agency headquartered in Southfield, Michigan. Founded in 1972, the company specializes in driving brand growth through data-driven shopper insights, retail consultancy, and innovative technology. The agency is well-known for its proprietary AI-powered platform, Marilyn, which provides predictive commerce intelligence to optimize marketing performance across various retail channels. While primarily a marketing firm, it maintains a significant healthcare and pharmaceutical practice, serving major clients such as Pfizer to develop specialized shopper marketing strategies for health products and vaccinations. In September 2024, the agency was acquired by Publicis Groupe for an estimated $600 million to enhance its global commerce and data capabilities.
