Viant

A publicly traded, independent people-based DSP competing with The Trade Desk and Google DV360, with a focus on CTV and cookieless identity solutions

Viant Technology (NASDAQ: DSP) is a publicly traded advertising technology company founded in 1999 and headquartered in Irvine, California. The company operates Adelphic, its flagship demand-side platform (DSP), which enables advertisers and agencies to plan, buy, and measure programmatic advertising campaigns across a wide range of digital channels including connected TV (CTV), linear TV, desktop, mobile, audio, and digital out-of-home. Viant's people-based approach leverages a proprietary identity framework built on registered user data, allowing advertisers to target real people rather than cookies or device IDs — a significant differentiator as the industry moves away from third-party cookies. Viant's platform is distinguished by its household-level identity graph, which links multiple devices and channels to individual consumers, enabling more precise targeting, frequency management, and attribution. The company serves a broad range of advertising agencies, brands, and media buyers, with particular strength in CTV and omnichannel campaign execution. Viant went public via a direct listing on NASDAQ under the ticker symbol DSP in February 2021, underscoring its positioning as a pure-play DSP in the programmatic ecosystem. In the competitive AdTech landscape, Viant competes with other major DSPs such as The Trade Desk, DV360 (Google), and Amazon DSP. The company differentiates itself through its cookieless identity solution, deep CTV capabilities, and a focus on transparency and data ownership for its clients. Viant has continued to invest in AI-driven campaign optimization and measurement tools, positioning itself as a forward-looking platform for the post-cookie advertising era.
