StackAdapt Pushes to Win Holdco Business
StackAdapt, a Canadian ad tech company, is pursuing aggressive growth in 2025, supported by $235 million in funding announced in February to expand its team and gain market share for its demand-side platform across North America and beyond. A core part of the strategy is to win business from major holding companies (holdcos), which manage multiple agency brands but involve many stakeholders and lack a single global mandate. StackAdapt executives Chris Keenan and Kim Marchan emphasize differentiating through vertical-focused solutions (B2B, healthcare, auto, and political) and in-house data capabilities, including brand lift studies and footfall measurement. The company highlights its approach of ingesting data at the signal level rather than via aggregated segments to enable granular insights and measurement. With agencies increasingly adopting outcomes-based remuneration, StackAdapt stresses flexibility, potential co-development with holdcos, and seamless integration into existing tech stacks as entry points for collaboration.
Strategic expansion into HoldCos; mid-level industry impact without a single groundbreaking milestone.
