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:
Composable API-first Controls
No black boxes. No walled gardens. Bring your own data, bidding logic, and attribution models to customize a stack that works for you – and adapt it as your needs evolve.
High-Impact Creative Everywhere
We power immersive, opt-in formats across CTV, display, mobile, and DOOH that engage audiences without disrupting them – helping your brand stand out on every screen.
Transparent AI Optimization
Our AI doesn’t hide behind mystery algorithms. We show you exactly how decisions are made and how performance is driven – so you’re always in the loop, and always in control.
Curated, Brand-Safe Inventory
Get access to premium, high-quality media placements aligned to your verticals, KPIs, and cultural moments – curated for real relevance and impact.
Real-World Results
From CRM onboarding to foot traffic attribution, we make it easy to measure real business outcomes – not just clicks and impressions.
For marketers caught off guard by the Xandr news, it’s natural to ask: What’s next?
At MediaMath by Infillion, we pioneered the DSP model. Now, we’re setting the standard for what the next generation of programmatic should be: open, accountable, and built to drive real performance in a fragmented media world.
