Viant Technology

Mid-tier independent DSP specializing in people-based advertising and omnichannel campaign execution

Viant Technology is a people-based advertising technology company that operates a demand-side platform (DSP) enabling advertisers to plan, buy, and measure digital advertising campaigns across multiple channels. The company's platform leverages its proprietary identity graph, built from deterministic data, to help brands reach specific audiences across connected TV (CTV), linear TV, mobile, desktop, audio, and digital out-of-home (DOOH) environments. Viant differentiates itself through its people-based approach to advertising, which focuses on reaching real people rather than relying solely on cookies or device IDs. Founded in 1999 and publicly traded since 2021, Viant serves enterprise brands, agencies, and marketers seeking omnichannel programmatic advertising solutions. The company's self-service platform, Viant DSP (formerly Adelphic), provides access to premium inventory and advanced targeting capabilities powered by its Viant Household ID. With a focus on privacy-compliant, cookie-independent advertising solutions, Viant positions itself as a leader in the transition toward identity-based advertising in a post-cookie digital landscape.
