MediaMath
MediaMath's Overview
MediaMath was a pioneering global demand-side platform (DSP) that empowered marketers to buy and optimize digital advertising programmatically across various channels. Founded in 2007, it was known for its TerminalOne Marketing Operating System®, offering advanced tools for audience targeting, campaign management, and performance analytics. In June 2023, MediaMath filed for Chapter 11 bankruptcy. Subsequently, in July 2023, its assets, including its core platform technology and talent, were acquired by Infillion, an advertising technology company. The MediaMath platform's capabilities are being integrated into Infillion’s broader suite of advertising solutions, aiming to provide enhanced programmatic offerings to brands and agencies.
