About

Viant Technology (NASDAQ: DSP) is a publicly traded advertising technology company founded in 1999 and headquartered in Irvine, California. Its flagship product, Adelphic, is a self-service demand-side platform (DSP) that enables advertisers and agencies to run programmatic campaigns across connected TV (CTV), linear TV, desktop, mobile, and other digital channels.
