Bridge Media Services was built by someone who spent four decades in advertising, running a media accountability firm, holding a patent for invoice reconciliation, and wondering why certain fundamental problems in media transparency were still unsolved. Now they are.

Thomas Bridge started in advertising in 1986. Over the following decade, he built a deep understanding of how media money actually moved, from planning to buying to invoicing to reconciliation, that led him to found Media Management, Inc. (MMi) in 1995, an independent media accountability firm. The premise was straightforward: someone needed to verify that what advertisers paid for was what they actually received. That someone didn't exist yet.

MMi spent 27 years doing that work at scale. Over its history, the firm managed accountability for more than $100 billion in U.S. media billings, including significant digital media, on behalf of clients including General Motors, AT&T, Walmart, Home Depot, T‑Mobile, Mazda, Subway, AstraZeneca, and many other leading U.S. advertisers. Many of those relationships lasted more than a decade.

The work required integrating data from every part of the media supply chain: Nielsen audience data, SQAD rate intelligence, agency buys, and media property invoices. Thomas's approach to that reconciliation problem became the basis for a U.S. patent: a method and system for reconciling advertising invoices and ensuring prompt payment.

In 2022, Ebiquity plc, the global leader in media management and accountability, acquired MMi. Thomas served as Ebiquity's President, North America, through 2023.

Today, Bridge Media Services continues that mission, combining decades of media accountability expertise with modern AI-powered tools to help agencies and advertisers achieve the clarity and transparency their media investments deserve. Our subsidiary enso brings this philosophy to the daily reporting challenge, automating what used to take teams days to produce.
