About
A publicly traded, independent DSP competing in the mid-to-large enterprise segment with a differentiated people-based identity and CTV-focused strategy
Viant is a programmatic advertising technology company that has been empowering marketers to create, execute, and measure advertising campaigns since 1999. 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. 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. 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. 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. 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.
