DOmedia

DOmedia provides software for planning, buying, and selling out-of-home media, serving as a technology platform for the outdoor advertising industry across the United States and Canada. The company offers products tailored to two main audiences: professional media buyers at agencies and brands, who use its tools to handle every aspect of out-of-home media, and media sales organizations, who use its platform to manage and market their inventory. DOmedia also operates BillboardsIn.com, an online marketplace that lets local advertisers discover and purchase billboard and other out-of-home space directly, with coverage described as spanning more than two hundred North American cities.

Its platform features include interactive mapping to compare available ad space, along with campaign booking and management tools that support local, regional, and national advertisers. DOmedia reports a broad user base that includes major holding companies and national media owners such as GroupM, Lamar, Outfront, and Vistar, together with more than twelve hundred agencies and media sellers. The company emphasizes reaching first-time out-of-home buyers through its marketplace, positioning itself as a modernization layer that connects buyers and sellers rather than as a media owner or traditional agency.

Based in Columbus, Ohio, DOmedia presents its software as neutral infrastructure for the out-of-home market, supporting billboards, transit, and digital placements through a single set of planning and transaction tools. Its overall proposition centers on marketplace access, data, and workflow software that streamline how out-of-home media is planned, bought, and sold nationally.
