About the brand ❤️
AppNexus is an American ad tech company founded in 2007 that developed one of the most influential programmatic advertising platforms in the digital media industry. Based in New York City, its cloud‑based technology enabled real‑time buying and selling of online ads, offering demand‑side (DSP) and supply‑side (SSP) capabilities alongside advanced analytics and auction infrastructure. The platform supported publishers, advertisers, and agencies worldwide, processing large volumes of ad impressions across formats such as display, mobile, and video. In 2018, telecommunications giant AT&T acquired AppNexus and folded it into its newly created Xandr division; in 2021–2022, Xandr (including AppNexus technology) was sold to Microsoft and integrated into Microsoft Advertising. While the AppNexus brand has been subsumed under Microsoft’s broader advertising business, its core technologies continue to power programmatic ad services globally.
