Nexage

Pioneer and leading mobile ad exchange before acquisition

Nexage was a pioneering mobile advertising exchange platform that revolutionized programmatic advertising in the mobile ecosystem through sophisticated real-time bidding (RTB) technology. Founded in 2009, the company established itself as one of the first and largest mobile-focused ad exchanges, creating a transparent marketplace that connected mobile app publishers with advertisers and demand-side platforms. Nexage's platform processed billions of ad impressions monthly, enabling publishers to maximize revenue through automated auction-based selling while providing advertisers with efficient access to mobile inventory. The company played a critical role in bringing programmatic advertising principles to mobile, at a time when the mobile advertising market was rapidly expanding but lacked the sophisticated infrastructure available in desktop display advertising. Nexage was acquired by Millennial Media in 2013 for approximately $108 million, which was subsequently acquired by AOL in 2015 for $238 million. AOL was then acquired by Verizon, and the Nexage technology was eventually integrated into Verizon Media's broader advertising technology stack, which later became part of Yahoo following Verizon's sale of its media assets to Apollo Global Management in 2021.
