About
A leading independent people-based DSP competing in the programmatic advertising space, with particular strength in connected TV and cookieless identity solutions
Viant Technology is a publicly traded advertising technology company that operates a sophisticated demand-side platform (DSP) known as Adelphic, purpose-built for people-based programmatic advertising. The platform enables advertisers and agencies to reach real, authenticated audiences across connected TV (CTV), desktop, mobile, and other digital channels by leveraging a proprietary identity graph built on first-party data rather than third-party cookies. Viant's people-based approach ties ad exposures to actual households and individuals, enabling more precise targeting and closed-loop measurement that links ad spend to real-world outcomes. Viant's platform is particularly distinguished by its deep investment in connected TV and omnichannel advertising capabilities, positioning the company as a significant player in the rapidly growing CTV advertising market. The company's Household ID technology underpins its identity resolution capabilities, allowing advertisers to unify audience data across devices and channels without relying on deprecated tracking mechanisms. Viant also offers robust reporting and attribution tools that help marketers understand campaign performance and optimize media spend. Trading on NASDAQ under the ticker symbol DSP, Viant serves a broad range of enterprise brands and independent agencies seeking a transparent, data-driven alternative to walled garden advertising ecosystems. The company competes with major DSPs such as The Trade Desk, Google DV360, and Amazon DSP, differentiating itself through its people-based identity framework, CTV focus, and commitment to cookieless advertising solutions. Viant has grown its platform capabilities through both organic development and strategic acquisitions, cementing its role as an independent, full-stack programmatic advertising solution.
