EMX Digital

Specialized SSP focused on header bidding technology and publisher yield optimization, operating as part of Magnite

EMX Digital operates as a supply-side platform (SSP) specializing in header bidding technology and programmatic advertising solutions for digital publishers. The company provides a comprehensive suite of tools designed to help publishers optimize their ad inventory across display, video, and native formats while maximizing yield through real-time bidding competition. EMX Digital functions as a subsidiary within the Cadent (formerly Telaria) family of companies, which was acquired by Magnite in 2020. Despite these ownership changes, EMX continues to operate as a distinct brand offering its header bidding wrapper technology and SSP services. The platform focuses on delivering transparent, efficient programmatic solutions that give publishers control over their inventory while providing access to premium demand sources. EMX Digital's technology emphasizes speed, reliability, and advanced analytics to help publishers make data-driven decisions about their monetization strategies. The company serves a range of digital publishers from mid-market to enterprise-level clients, positioning itself as a technology-forward partner in the increasingly complex programmatic advertising ecosystem. As part of the larger Magnite organization (the world's largest independent SSP), EMX Digital benefits from enhanced scale and resources while maintaining its specialized focus on header bidding innovation and publisher-centric solutions. The platform continues to evolve its offerings to address challenges like cookie deprecation, identity resolution, and the shift toward privacy-first advertising technologies.
