VIOOH Expands U.S. Footprint Through Strategic Partnership with Dolphin OOH

VIOOH, a leading global digital out-of-home (DOOH) supply-side platform, has entered into a strategic partnership with Dolphin OOH to expand access to high-quality DOOH inventory across the United States.

Under the agreement, VIOOH will provide programmatic access to more than 5,000 digital screens in major U.S. cities, delivering over 50 million monthly impressions. Dolphin’s network spans a wide range of high-traffic environments, including malls, transit stations, grocery stores, pharmacies, gyms, convenience stores, office supply retail outlets and urban panels.

The inventory covers key metropolitan markets such as New York City, Boston, Chicago, Dallas-Fort Worth, Houston, Los Angeles, Miami, Orlando, Atlanta and Long Beach. Grocery stores account for 112 million monthly impressions, while convenience stores generate 63 million, pharmacies 42 million, urban panels 27 million and malls 10 million impressions per month. Additional reach is provided through transit, gyms and specialty retail locations.

The integration enables advertisers to plan, launch and manage campaigns seamlessly across Dolphin’s screen network via VIOOH’s platform. Buyers benefit from enhanced flexibility, precision targeting and operational efficiency, supporting measurable outcomes in dynamic urban environments.

Brand safety is a central component of the partnership. Dolphin applies comprehensive screen and location tagging to ensure a secure advertising environment, offering a 100 percent completion rate and zero ad fraud, according to the company.

Gavin Wilson, Global Chief Commercial Officer at VIOOH, said the partnership provides access to high-frequency environments where consumers are close to purchase decisions. He noted that Dolphin’s scale and focus on brand safety deliver the quality and confidence buyers require.

Josey George, CEO of Dolphin, said the collaboration unlocks the full programmatic potential of its network, connecting U.S. inventory to global demand through VIOOH’s technology and international reach.

As programmatic DOOH continues to grow, the partnership reflects broader industry momentum toward automation, data-driven targeting and omnichannel integration. By combining scale, context and technology, VIOOH and Dolphin aim to strengthen DOOH’s role within the evolving media mix in North America.
