Telaria

Was the leading pure-play sell-side video and CTV ad management platform for premium publishers prior to its merger with Rubicon Project to form Magnite in 2020.

Telaria was a specialized sell-side platform (SSP) focused on video and connected television (CTV) advertising technology. Founded as Tremor Video, the company rebranded to Telaria in 2017 to reflect its strategic pivot from a managed services video ad network to a pure-play software platform for premium publishers. Telaria's platform gave publishers sophisticated tools to manage, monetize, and optimize their video ad inventory across CTV, OTT, desktop, and mobile environments, with particular strength in the rapidly growing streaming television space. Telaria distinguished itself by focusing exclusively on the sell side, positioning itself as a neutral, publisher-first technology partner at a time when many competitors operated conflicted buy-side and sell-side businesses simultaneously. Its CTV capabilities were especially notable, attracting major streaming publishers and broadcasters as clients. The company was publicly traded on the NYSE and built a reputation for transparency and premium video monetization expertise. On April 1, 2020, Telaria completed a merger of equals with Rubicon Project to form Magnite, which became the largest independent omnichannel SSP in the programmatic advertising industry. Telaria's CTV technology formed the backbone of Magnite's CTV business, which was later further strengthened by the acquisition of SpotX and the SpringServe ad server. The Telaria brand was retired following the merger, but its technology and publisher relationships became foundational assets of Magnite's market-leading CTV offering.
