Viant Technology

Independent people-based DSP with strong CTV and cookieless identity capabilities, positioned as a credible alternative to The Trade Desk and Google DV360

Viant Technology is a publicly traded advertising technology company that provides a people-based programmatic advertising platform, enabling brands, agencies, and marketers to plan, execute, and measure digital advertising campaigns across virtually every channel and device. Its flagship product, the Adelphic DSP, is built on a proprietary identity framework that links digital advertising to real people rather than cookies, leveraging a database of over 115 million registered U.S. households. This people-based approach allows for more precise audience targeting, cross-device attribution, and closed-loop measurement that connects ad exposure to real-world outcomes. Viant's platform is particularly distinguished by its strength in connected TV (CTV) and converged TV advertising, positioning the company at the intersection of traditional TV buying and modern programmatic execution. The company offers tools for linear TV planning alongside CTV and streaming inventory, giving advertisers a unified view of their television investments. Viant also provides cookieless targeting solutions through its Household ID technology, which has become increasingly relevant as the industry moves away from third-party cookies. Founded in 1999 and headquartered in Irvine, California, Viant went public on the Nasdaq in February 2021 under the ticker DSP. The company serves a broad range of enterprise advertisers and independent agencies, competing with major DSPs like The Trade Desk, DV360, and Amazon DSP. Viant differentiates itself through its people-based identity graph, cookieless infrastructure, and deep CTV capabilities, making it a notable independent alternative in the programmatic ecosystem.
