Viant

Independent demand-side platform specializing in CTV and AI-powered programmatic advertising, positioned as a transparent alternative to walled garden ad platforms

Viant is a programmatic advertising technology company that has been empowering marketers to create, execute, and measure advertising campaigns since 1999.¹ Its flagship demand-side platform specializes in CTV and AI-powered programmatic advertising, with a Supply Path Optimization product called Direct Access that connects advertisers to premium CTV inventory through more direct and cost-efficient paths.² Direct Access, which enables the DSP to reach streaming publishers without an exchange intermediary, was extended in September 2026 from open-market buying to negotiated private and guaranteed deals.² Investors have valued Viant in part for its acquisitions of proprietary data sets, including TVision, Iris.TV, and Lockr, which support its measurement and targeting capabilities.³ Viant positions itself as an independent alternative to walled garden platforms, with its COO asserting that advertisers and agencies are increasingly pushing back against the self-attributing tactics and lack of transparency offered by competing platforms.³ Viant Technology Inc. trades on NASDAQ under the ticker DSP and was named to the 2026 Fortune Best Workplaces in Advertising & Marketing™ List for the third consecutive year.² Source 1: viantinc.com — About Us Source 2: viantinc.com — Latest Company News & Official Press Releases Source 3: adexchanger.com — Viant Sees A Growth Wave Coming, But First Marketers ...
