Telaria, Inc. operated as a fully programmatic, sell-side software platform (SSP) dedicated to premium video publishers. The company's advanced Video Management Platform (VMP) enabled publishers to manage and monetize their video advertising inventory across all screens, including Connected TV (CTV), mobile, and desktop. Telaria provided tools for yield optimization, inventory management, robust analytics, and direct-sold campaign management, empowering publishers to maximize revenue from their video content. It emphasized transparency, brand safety, and control for publishers in the complex programmatic advertising ecosystem. In April 2020, Telaria merged with Rubicon Project to create Magnite (NASDAQ: MGNI), becoming the world's largest independent sell-side advertising platform.
Core corporate operations, including executive leadership, product strategy, engineering oversight, global sales and marketing direction, and administrative functions.
Modern office space in a central Manhattan location, part of the historic former New York Times Building complex, designed to foster collaboration and reflect its status as a leading ad-tech firm.
Telaria cultivated a dynamic, innovative, and data-driven work culture, characteristic of the ad-tech industry. There was a strong emphasis on publisher success, transparency in media transactions, and rapidly adapting to the evolving digital video and CTV landscape.
As the global headquarters, this New York office served as the central hub for Telaria's strategic decision-making, technological innovation, and coordination of its worldwide operations in the competitive video SSP market, particularly spearheading its growth in Connected TV.
Prior to its merger with Rubicon Project to form Magnite, Telaria had established a significant global presence with offices and operations across North America, Europe (EMEA), Latin America, and the Asia-Pacific (APAC) region. This international network supported vital functions including sales, publisher relations, account management, and technical support, enabling Telaria to effectively serve a diverse, global base of premium video publishers and connect them with worldwide advertising demand, especially in the burgeoning CTV space.
