AdWalls

AdWalls is an out-of-home media company that describes itself as an indoor billboard specialist, headquartered in Honolulu, Hawaii. The company builds and manages custom placements in everyday indoor and semi-indoor environments, giving national brands and local businesses ways to reach audiences beyond traditional roadside billboards. Its format menu includes mall frames and displays, office-building and elevator advertising, parking-garage placements, floor graphics, chandeliers, transit and bus advertising, and mobile billboards, as well as media in hospitals, airports, and government buildings.

Hawaii remains the core of the business, but AdWalls extends its reach through a portfolio of parking garages and other venues in top mainland markets, operating across roughly 15 designated market areas that include New York, Boston, Chicago, and Los Angeles. By concentrating on places where consumers walk, wait, and dwell, the company positions its inventory as a high-dwell-time complement to outdoor formats, capturing attention in controlled environments where audiences are receptive. AdWalls emphasizes custom-built media and results, working with clients on placement strategy and creative execution tailored to specific audiences and neighborhoods.

Now in its third decade of operation, the company serves both broad general-market campaigns and targeted local programs. Its coverage across multiple property types allows advertisers to assemble multi-market indoor buys from a single partner rather than negotiating venue by venue. The AdWalls website details its formats, market coverage, and contact information, and the company maintains an active presence on social platforms including Facebook, Instagram, and LinkedIn.
