Market Position
Former leading independent DSP, now integrated into Infillion
Overview
MediaMath was a pioneering programmatic advertising technology company founded in 2007 that developed one of the first demand-side platforms (DSPs) in the digital advertising industry. The company's flagship product, the TerminalOne Marketing Operating System, enabled marketers and agencies to plan, execute, and optimize digital advertising campaigns across display, video, mobile, and social channels using real-time bidding and data-driven audience targeting. MediaMath was known for championing transparency in programmatic advertising and advocating for ethical data practices in the AdTech ecosystem. At its peak, MediaMath was considered one of the leading independent DSPs, competing with major players like The Trade Desk and Google's DV360. The company served enterprise brands and agencies globally, processing billions of ad transactions daily. However, MediaMath faced financial difficulties and filed for Chapter 11 bankruptcy in June 2023. The company was subsequently acquired by Infillion (formerly TEGNA) in July 2023, which integrated MediaMath's technology and talent into its connected TV and digital advertising platform. This acquisition marked the end of MediaMath as an independent entity but preserved its technology within Infillion's broader advertising solutions.
