Tempus AI

Tempus AI is a Chicago-based health technology company that has built one of the world's largest libraries of clinical and molecular data, paired with an AI operating system that helps physicians and researchers make data-driven decisions in oncology, cardiology, radiology, and beyond. Founded in 2015 by Groupon co-founder Eric Lefkofsky after his wife's cancer diagnosis, the company sequences patient genomes, structures messy clinical records, and turns that data into diagnostics and AI tools used across a majority of U.S. academic medical centers. It went public on Nasdaq in June 2024 under the ticker TEM.
