Telaria

Was a leading pure-play sell-side video and CTV ad management platform before merging to form Magnite, the largest independent omnichannel SSP.

Telaria was a specialized sell-side video advertising management platform headquartered in New York City, focused on helping premium publishers monetize their video inventory across connected TV (CTV), over-the-top (OTT), desktop, and mobile environments. The company offered a comprehensive suite of tools including a video management platform, header bidding solutions, and advanced analytics, enabling publishers to maximize yield and maintain control over their ad decisioning. Telaria was particularly distinguished by its early and deep investment in the CTV and OTT space, positioning itself as a critical infrastructure partner for streaming publishers at a time when the market was rapidly expanding. Originally founded as Tremor Video, the company rebranded to Telaria in 2017 to reflect its evolution from a demand-side business to a pure-play sell-side platform. This strategic pivot allowed Telaria to focus exclusively on publisher monetization, differentiating itself from competitors with a conflict-free SSP model. The company was publicly traded on the NYSE under the ticker TLRA and built a strong roster of premium publisher clients in the streaming and broadcast space. On April 1, 2020, Telaria completed a merger of equals with Rubicon Project to form Magnite (NASDAQ: MGNI), the largest independent omnichannel SSP in the world. Both the Telaria and Rubicon Project brand names were retired as part of the transaction. Telaria's CTV technology became the foundation of Magnite's CTV business, which was later further strengthened through the acquisition of SpotX and the SpringServe ad server, with SpringServe now serving as the CTV ad serving backbone within the Magnite platform.
