About SpotX

SpotX provides a video ad-serving and programmatic platform. Media owners use it to manage inventory and monetize desktop, mobile, CTV/OTT and outstream video. It connects them with brands, agencies, trading desks and DSPs, and earns revenue from ad transactions on the platform. Founded in 2007 as SpotXchange, it was bought by RTL Group (65% stake in 2014, 100% in 2017). Magnite acquired it in 2021 for about $1.17 billion.
