Editorial Review by TopAdNetworks
MediaMath is a very different DSP in 2026 than it was in its standalone days. The brand now lives inside Infillion, and the current product pitch leans hard into composability, open APIs, and transparent control rather than the usual black-box DSP language.
The strongest part of the offer is the combination of execution and data. Infillion says XGraph, its privacy-safe identity spine, powers the platform and enables layering CRM data, activating lookalikes, and measuring performance within a cookieless framework. For teams trying to keep targeting useful while third-party signals weaken, that is a serious selling point.
The other big advantage is breadth without fragmentation. Infillion MediaMath gives access to video, CTV, audio, display, and digital out-of-home, plus curated marketplaces and brand-safe inventory.
Infillion also says its TrueX guaranteed attention format delivers 25% to 40% higher recall and 2x engagement versus industry norms, which is a strong claim and one of the more concrete value props on their product page.
Company Overview
Infillion's company page places MediaMath inside a broader platform built around four pillars: Demand, Supply, Data, and Creative.
The company says it has completed 11 acquisitions since 2016, and MediaMath is one of the acquisitions that completed the Demand pillar.
Infillion also says it is building a composable advertising technology platform designed to compound value across business units and customer types.
That matters because MediaMath is no longer just a pure DSP in the old sense. The current product sits within a stack that also includes TrueX, Gimbal, private marketplaces, sports, and location intelligence, giving Infillion more control over supply, identity, and measurement than a standalone DSP typically has.
Infillion's New York HQ is listed at 853 Broadway, 21st Floor, New York, NY 10003, with additional offices in Los Angeles, Miami, Seattle, Chicago, and Granville, Ohio. That footprint aligns with the enterprise positioning the company pushes on the current site.
How The Platform Works
Infillion MediaMath works as a composable enterprise DSP.
Buyers can activate through REST APIs, the Infillion Agent Connector, or the UI, then connect identity, data, creative, and measurement partners through open APIs.
The platform is designed so teams can switch between managed, self-serve, and agentic operating modes without rebuilding campaigns.
On the optimization side, Infillion says its AI engine learns and acts in real time, with transparent signals from bid to budget.
The company highlights dynamic budget allocation and signal-level insights tied to ROI, CPA, and engagement, so optimization is meant to be visible instead of hidden behind a black box.
For measurement, the platform goes beyond clicks and impressions. Infillion MediaMath includes Arrival for footfall attribution, Uplift for real-time brand lift surveys, third-party measurement for closed-loop outcomes, and log-level reporting updated three times daily. That makes it more measurement-heavy than many traditional DSPs.

Key Differentiators
MediaMath's biggest differentiators in 2026 are not just the DSP basics. They are the way Infillion packages identity, measurement, and premium inventory into a composable enterprise system.
1. Composable DSP Architecture
The current product is built around open APIs and modular components, which gives teams more control than a rigid all-in-one DSP. Clients can activate via REST APIs, the Agent Connector, or the UI, and can move between managed and self-serve models without disrupting campaigns.
2. Privacy-Safe Identity Spine
XGraph is the platform's identity core. It connects people, households, and behaviors across screens, while supporting deterministic U.S. mapping, opt-in location data, survey data, and interoperable IDs such as UID2, RampID, and ID5. That makes identity more portable than cookie-dependent workflows.
3. Measurement Beyond Proxies
Arrival, Uplift, third-party measurement, and log-level reporting make the platform useful for buyers who care about actual outcomes. Footfall, brand lift, and sales impact are all part of the measurement story, which is stronger than simple last-click reporting.
4. Premium Inventory and Guaranteed Attention
The current MediaMath page gives instant access to brand-safe inventory across video, CTV, audio, display, and DOOH. It also highlights TrueX's guaranteed attention with 25% to 40% higher recall and 2x engagement versus industry norms, which is a rare quantified claim in the enterprise DSP space.
Ideal Use Cases
MediaMath works best for teams that want enterprise DSP control with first-party data, cross-channel execution, and real measurement.
- Brands running multi-channel video and CTV campaigns.
- Retail and commerce media teams need deterministic data and closed-loop measurement.
- Agencies that want managed, self-serve, or agentic workflows in one stack.
Target Clients
Advertisers
Infillion targets agencies, brands, independent agencies, and holding companies, as well as retail media networks and commerce media networks. The current product is especially suited to advertisers who need transparent control over identity, bidding, measurement, and premium supply.
Publishers
MediaMath is less publisher-centric than a classic SSP, but Infillion's broader platform includes supply-side products, private marketplaces, and curated inventory relationships. That means publishers and media owners fit best when they are part of a larger supply or marketplace strategy, not when they are looking for a simple standalone monetization tool.
Pricing & Business Model
Infillion MediaMath does not publish a public price card on the product page, which fits its enterprise positioning. Instead, the site emphasizes flexible operating modes, open APIs, and custom workflows, all of which suggest contracted pricing and platform-specific commercial terms rather than self-serve checkout pricing.
Pricing is shaped by channel mix, identity integration, measurement depth, and the amount of managed support a client needs. A CTV-heavy media plan with deterministic identity and log-level reporting will naturally look different from a basic display activation, and the platform is built to support that variability.
On the buying side, MediaMath functions as an enterprise DSP, enabling advertisers to effectively buy managed or self-serve access to premium inventory and data.
On the measurement side, Infillion layers in Arrival, Uplift, and third-party measurement, so buyers can evaluate footfall, brand lift, and sales impact rather than only clicks.
