About
Largest independent sell-side platform globally, with particular leadership in CTV/streaming video advertising
Magnite is an American online advertising technology company based in Los Angeles, California, formed through a merger of Rubicon Project and Telaria in 2020. The merger made Magnite the world's largest independent omnichannel sell-side platform. Operating on the sell side of the ad stack, Magnite provides publishers and media owners with technology and services designed to maximize the value of their inventory, offering true global scale, advanced brand protection, and tools to help advertisers find the audiences they want. The platform supports a wide range of formats — including streaming, online video, display, and audio — serving both buyers and sellers across these channels. Magnite distinguishes itself by operating independently of any parent company, positioning its decision-making around client interests rather than those of a larger corporate entity.
