Vistar Media

Vistar Media is a global provider of technology solutions for out-of-home (OOH) media, offering an end-to-end programmatic ecosystem designed to facilitate data-driven, automated, and measurable digital out-of-home (DOOH) transactions. Founded in 2011, the company is headquartered in New York, NY, and has a presence in numerous countries across North America, Europe, and Oceania. Vistar Media's core mission is to leverage technology and data to transform OOH into a strategic and measurable channel, enabling brands and marketers to connect with consumers effectively in the physical world. The company provides a comprehensive suite of platforms, including a global demand-side platform (DSP) for buyers to activate data-driven programmatic campaigns, a supply-side platform (SSP) to connect signage operators to digital revenue, an ad server, and a device and content management system called Cortex. This integrated technology stack has established Vistar Media as a significant marketplace for OOH transactions globally.

Vistar Media works with a wide range of clients, from hundreds of brand marketers to media owner networks, powering OOH campaigns that aim to inform, entertain, and attract audiences. The company emphasizes the unique ability of OOH advertising to motivate and delight consumers by intersecting ad space with time and place. Vistar Media's platform hosts an extensive inventory of OOH media, providing the scale, data, and expertise necessary for brands to capture attention. The company has facilitated numerous programmatic campaigns and boasts a significant number of digital screens available globally. Vistar Media has also been recognized for its company culture, prioritizing employee success, growth, and well-being. In early 2025, T-Mobile announced its intention to acquire Vistar Media, a move expected to further enhance Vistar's offerings and expand its reach in the advertising sector by combining Vistar's ad-tech platform with T-Mobile's customer insights and data.
