Our Story

Our Name

How does a brand with more than 140 years under its belt invent the new normal? Considering our past and addressing the present, we took great care in building a new kind of advertising company that leads with curiosity and courage as we move toward the future.

Looking ahead requires an understanding of what came before.

We took to the archives to reconnect with our roots,  reintroducing ourselves to Alexander Graham Bell — the inventor and pioneer — to ask who he might be if he were empowered with the tools and technology of today.

The name ‘Xandr’ reflects our entrepreneurial spirit and dedication to using our history of innovation as the roadmap for propelling an industry forward.

A Look Back

Xandr started as a collective of legacies and passions. From the former AppNexus marketplace and enterprise technology, to AT&T’s data assets, clypd’s technology platform, to our partnership with AT&T and WarnerMedia, we’ve joined together to move the industry forward and to solve for advertisings greatest challenges. The connections we make through advertising fund award-winning journalism, music, video, and games-all at little or no cost to the consumers who enjoy open access to premium content.

How Far We’ve Come

Xandr is committed to powering a global marketplace for premium advertising by building real solutions to move the advertising industry forward. In its first year as AT&T’s advertising company, Xandr launched numerous flagship products, including the buying platform, Xandr Invest, and its selling platform, Xandr Monetize. One year later, Xandr revealed the next evolution of Xandr Invest, enhanced for the future of TV by allowing advertisers to activate audiences and unique data insights across multiple programmers. Xandr is primed for the convergence of TV and digital advertising, making it a reality for buyers and sellers in one of the world’s largest premium advertising marketplace.
