Quartile

Quartile describes itself as the world's largest retail media optimization platform. The company applies patented artificial-intelligence technology to advertising on major retail channels, among them Amazon, Google, Walmart, Instacart and Meta, combining cross-channel data to manage what it calls a nonlinear purchase funnel. Its Quartile Platform brings together cross-channel retail media insights, performance reporting and opportunity identification, delivered alongside white-glove managed service.

The company's scale is considerable. Quartile serves more than 5,300 brands and sellers worldwide and manages over $2 billion in retail advertising spend a year, which in turn drives some $25 billion in annual managed sales. Clients report an average 41% increase in return on ad spend. Work spans AI and machine learning, marketing automation, budget optimisation and full-funnel performance optimisation.

Quartile employs more than 300 certified professionals and operates globally. Its working model pairs automation with human expertise: staff build bespoke solutions for individual clients rather than applying a standard template, with an emphasis on measurable outcomes. The company places equal weight on strategic advisory and on the technology itself.
