Magnite

Magnite operates B2B advertising infrastructure that sits on the sell side of programmatic media trading. It creates value by helping publishers and media owners expose inventory to demand sources, improve yield, unify direct and programmatic monetisation, and package premium supply for buyers. The business combines core SSP transaction rails with adjacent software modules such as CTV ad serving, header bidding management, identity and audience activation, inventory discovery and managed demand facilitation.

Magnite is a publicly listed US advertising technology company focused primarily on sell-side infrastructure for publishers and media owners. Its core business is operating supply-side and ad serving software that helps publishers manage, sell and optimise advertising inventory across display, online video, audio, digital out-of-home and especially connected TV. Following the Telaria merger and the acquisitions of SpotX and SpringServe, the company broadened its position in streaming and video monetisation.

Magnite makes money chiefly by taking a percentage of advertising spend transacted through its platforms, supplemented by software and platform fees tied to ad serving, header bidding management, data activation, curated marketplace workflows and managed programmatic services. Its direct customers are mainly publishers, broadcasters, streaming platforms, media owners, agencies and advertisers buying premium programmatic supply, rather than consumers.
