Infillion MediaMath outperforms in competitive DSP showdown

Media Thesis, a performance marketing agency obsessed with ROI, set out to identify the most efficient DSP for driving cost-effective results across both premium and open-market inventory. During a high-stakes Q4 holiday campaign, legacy platforms failed to deliver the value clients demanded, prompting a head-to-head DSP test grounded in real performance data.

Determine which demand side platform delivers the strongest cost-efficiency and campaign performance across CTV and digital audio, using the same budget, targeting, and creative across both open exchange and premium inventory.

Media Thesis launched a controlled test with three leading DSPs running the same campaign parameters across CTV and digital audio. After identifying the top performer, they initiated a focused, head-to-head showdown: MediaMath vs. the incumbent leader.

Both platforms were given identical budgets, creatives, and geos, with premium inventory included. The goal was simple: determine which DSP could deliver stronger results in a real-world, high-pressure environment.

MediaMath Maximizes Performance—and Efficiency
MediaMath outperformed the leading DSP by wide margins across open exchange and premium direct environments, with a 40% CPM efficiency advantage for HBO Max video in one instance.

From CTV to digital audio, Media Thesis confirmed that MediaMath delivers what today’s performance marketers need most: more value, broader reach, and measurable impact for every dollar spent.

The success of this test led to a deeper partnership between Media Thesis and MediaMath, built on shared goals around performance, transparency, and premium inventory access.
