What We Do

Quadrivia is building Qu, a personal clinical assistant with wide capabilities across the care spectrum. It is designed by clinicians for clinicians, and the communities we serve.

According to the World Health Organization, there is a global shortfall of up to 18 million healthcare workers. A root cause of the worldwide challenge with the quality, accessibility and affordability of healthcare is this structural imbalance between elastic demand by population and constrained supply of providers.

Care is delivered globally in many different ways. By making Qu comprehensive, controllable and customizable, we aim to help healthcare professionals be in control of AI’s utility, safety and quality. Qu’s cognitive architecture of expanding agents is designed to support clinicians not just for a single task but across the full stack of routine clinical and administrative tasks, patient interactions, decision-making, chronic and post operative care, continuous monitoring and support, in multiple languages.
