ECI Media Management and Media Marketing Compliance are two of the world's leading media consultancies, pioneers in their respective media performance audit and compliance sectors. With complementary product offerings and skillsets, the two companies have collaborated for several years to drive value and savings for global advertisers.

Mindful of the urgent need among advertisers to simplify in an increasingly fragmented media landscape, we have formalized our collaboration in 2025, creating a partnership called ECIMMC. ECIMMC is our aligned service offering that integrates media performance auditing and contract compliance, while always maintaining strict data separation between clients and agencies. ECIMMC brings together the power, expertise and global experience of ECI and MMC, but with one client contract, and one client team. Together we can drive accountability, transparency and optimized media performance.
