Viant

Mid-tier independent DSP with a differentiated people-based identity and CTV focus, competing 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 distinguished by its people-based identity framework, which links digital advertising to real, authenticated users rather than relying solely on cookies, giving it a differentiated position in a privacy-first advertising landscape. Viant's core strength lies in its proprietary identity resolution capabilities, built around a registered user database of over 115 million U.S. households. This first-party data foundation allows advertisers to target, frequency-cap, and measure campaigns with greater accuracy than cookie-dependent alternatives. The company serves a broad range of advertising agencies, brands, and media buyers, with a particular emphasis on omnichannel campaign execution and closed-loop measurement. Its Household ID technology is central to its cookieless future strategy. In the competitive DSP landscape, Viant positions itself against larger players like The Trade Desk, Google DV360, and Amazon DSP, differentiating through its people-based approach, CTV focus, and transparent pricing model. The company went public via a direct listing on NASDAQ in February 2021 and has continued to invest in AI-driven automation, cookieless identity solutions, and CTV capabilities. Viant's revenue is primarily derived from platform fees and media spend processed through its DSP.
