StackAdapt

StackAdapt is a multi-channel, self-serve programmatic advertising platform, or demand-side platform (DSP), that helps media buyers plan, run, and optimize campaigns across a range of digital channels using AI-driven tools. Trusted by both SMB and enterprise customers across verticals such as B2B, healthcare, travel, and e-commerce, StackAdapt operates across North America, LATAM, EMEA, and APAC. Although its roots are in native advertising, the platform is now widely used by agencies and in-house teams for campaigns spanning channels including connected TV (CTV), display, audio, digital out-of-home (DOOH), email, and more.

For the OOH ecosystem, StackAdapt provides a unified DSP through which advertisers can plan, buy, optimize, and measure programmatic DOOH alongside their other media, rather than treating it as a separate, siloed channel. The company partnered with Broadsign in 2023 to unlock new OOH inventory on its platform, giving buyers access to premium global screens in high-traffic locations, and it has strengthened its DOOH capabilities through additional supply relationships. StackAdapt has introduced a map-first inventory discovery tool that lets advertisers visually explore and filter available screens by location, media owner, and venue type, replacing spreadsheets and static lists with real-world context, and supports programmatic guaranteed access to DOOH inventory.

As a performance-focused DSP, StackAdapt sits on the demand side of the programmatic DOOH ecosystem, connecting advertisers and agencies to screen-based inventory.
