Looking For A Successor To Xandr? MediaMath Is Engineered For What’s Next

Microsoft has officially announced it’s winding down Xandr, with a full transition expected by February 2026. In the wake of this news, advertisers are left to consider what is next for them. For many, this signals the end of an era — but it can also be the beginning of a smarter, more flexible future in programmatic advertising.

At MediaMath by Infillion, we’re experts in getting clients up and running quickly, as well as in the transfer of knowledge and in managing an API-first, world class DSP.

MediaMath is built for marketers and agencies. That means more control, more transparency, and better outcomes, delivered across every screen.
Here’s what we’re delivering today that others still aren’t:
