Magnite Selected by GroupM to Power GroupM Premium Marketplace in North America and as a Preferred Technology Partner Globally

Partnership will see GroupM consolidate omnichannel media buys across CTV, digital video, and display within Magnite in the US and Canada

NEW YORK – (February 24, 2022) – Magnite (NASDAQ: MGNI), the world’s largest independent sell-side advertising platform, has been chosen to power the GroupM Premium Marketplace in the US and Canada as well as a global preferred technology partner. GroupM will consolidate its programmatic media buying across omnichannel environments including CTV, digital video, and display within Magnite in the US and Canada. GroupM will leverage Magnite on a preferred basis globally across EMEA, APAC and LATAM.

“Magnite has been a trusted technology provider for a number of years and we are excited to officially leverage them as our primary exchange in the US and on a preferred basis globally to enhance our collective buying power,” said Andrew Meaden, Global Head of Investment at GroupM. “Consolidating our media investments within a central platform is a huge benefit to our global organization. Magnite’s strong relationships with top tier media owners and advanced technology across a range of screens and formats are two top reasons among many others that we are making this move.”

With technology at the heart of this preferred relationship, Magnite and GroupM will collaborate closely to simplify and optimize various aspects of advertising. As brands shift towards audience-based buying strategies, data enablement solutions will be an area of focus, as will measurement and forecasting. Magnite’s award-winning CTV platform, which features a real time data and analytics dashboard, gives buyers like GroupM live campaign performance updates. Leading publishers including Disney and Samsung utilize Magnite to manage and monetize their inventory. Additionally, GroupM will leverage the SpringServe ad server as the frontend for the GroupM Premium Marketplace.

“This partnership is indicative of how modern agencies are transforming media planning and execution, with GroupM leading the way on innovation,” said Sean Buckley, Chief Revenue Officer at Magnite. “We are excited to roll up our sleeves and collaborate with the GroupM team to make advertising more efficient and effective. This is another major milestone in streamlining the workflow between the buy and sell side, while continuing to scale digital media investment for the independent internet.”
