Xandr Invest

Premium enterprise DSP with strong video and CTV capabilities

Xandr Invest is a programmatic advertising demand-side platform (DSP) that was part of Xandr, formerly known as AppNexus before being acquired by AT&T in 2018. The platform provides advertisers and agencies with tools to execute data-driven media buying across display, video, mobile, native, and connected TV inventory. Xandr Invest offers advanced audience targeting, real-time bidding capabilities, and comprehensive analytics to optimize campaign performance. As part of the broader Xandr ecosystem, Invest works in conjunction with other Xandr products including Monetize (SSP) and Curate (marketplace). The platform is designed for sophisticated programmatic buyers who need enterprise-grade tools for managing complex, multi-channel advertising campaigns. In 2021, AT&T sold Xandr to Microsoft, which integrated the technology into its advertising solutions. Xandr Invest competes in the premium DSP market segment, offering access to quality inventory, advanced forecasting and planning tools, and integration with first-party and third-party data sources. The platform is particularly strong in video and CTV advertising, reflecting the evolution of digital advertising beyond traditional display formats.
