About Cartesian

Cartesian is building spatial intelligence for indoor environments to drive operational efficiency.

Our platform delivers accurate indoor positioning and actionable product location insights, helping retailers streamline operations, optimize workflows, and reduce inefficiencies. Leveraging RF signals, we provide a uniquely scalable, infrastructure-free solution already deployed by international fashion brands.
