Viant

Mid-tier independent DSP competing on people-based identity, CTV strength, and transparent pricing against larger platforms like The Trade Desk and Google DV360

Viant Technology (NASDAQ: DSP) is a publicly traded advertising technology company headquartered in Irvine, California, founded in 1999. 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 channels including connected TV (CTV), linear TV, desktop, mobile, audio, and digital out-of-home. Viant's platform is built around a people-based identity framework that ties advertising exposure to real households and individuals rather than relying solely on cookies, giving it a differentiated approach in a privacy-evolving landscape. Viant's core differentiator is its proprietary identity resolution technology, which leverages a database of hundreds of millions of registered users — largely inherited from its historical ownership of Time Inc.'s digital properties and other media assets — to enable deterministic audience targeting and cross-device measurement. The company offers a self-service and managed-service model, serving advertising agencies, brands, and media buyers who need transparent, data-driven campaign execution. Its Household ID technology allows advertisers to reach consumers across devices within the same household, a capability particularly valuable for CTV and streaming advertising. In the competitive DSP landscape, Viant positions itself against larger players like The Trade Desk, Google DV360, and Amazon DSP by emphasizing its people-based identity approach, transparent pricing (including a flat-fee SaaS-like model), and strong CTV capabilities. The company has made strategic investments in AI-driven media planning tools and cookieless targeting solutions, aiming to future-proof its platform as third-party cookies are deprecated. Viant went public via IPO on NASDAQ in February 2021 and continues to grow its revenue base primarily through platform fees and media spend processed through its DSP.
