VIOOH

VIOOH is a programmatic digital-out-of-home (DOOH) marketplace that connects media buyers and media owners through data and technology, headquartered in London. Launched in 2018 and originally established by JCDecaux, which retains a majority ownership stake alongside data specialist Veltys, VIOOH operates a premium global marketplace designed to make out-of-home advertising as accessible and automated as other digital channels. The platform serves two sides of the market: advertisers and media agencies seeking to plan and trade DOOH campaigns, and media owners looking to manage and maximize the value of their screen inventory.

VIOOH's capabilities include programmatic trading and inventory management, dynamic creative optimization, data-driven and location-based targeting, flight data targeting, and programmatic guaranteed deals, along with support for multi-channel campaigns that combine DOOH with channels such as social and connected TV. The marketplace integrates with dozens of demand-side platforms globally, giving buyers broad access to premium screens through the trading tools they already use. VIOOH trades programmatically across numerous international markets and works with major media owners on multiple continents, including JCDecaux estates and partners in markets such as the United Kingdom, France, Germany, Spain, China, Singapore, Australia, and the United States.

Positioned as an independent, technology-led player, VIOOH champions the role of DOOH within omni-channel digital strategies, helping the sector attract programmatic budgets and integrate more fully into automated media buying.
