# Listen: Chicago tech giant Eric Lefkofsky shares his journey from Groupon to precision medicine startup Tempus

[ Caitlin ](https://blog.matter.health/author/caitlin)  April 21, 2021

Eric Lefkofsky is one of Chicago’s most successful technology entrepreneurs. His entrepreneurial ventures include Groupon, Echo Global Logistics, Lightbank and, most recently, [Tempus](https://www.tempus.com/).

As the founder and CEO of Tempus, Eric has led the company — which uses machine learning and genomic sequencing to better understand cancer tumors — to become one of Chicago’s most valuable technology startups. Tempus raised $300 million last year, bringing their total financing to more than $1 billion and their valuation to $8.1 billion. The most recent raise has allowed Tempus to expand beyond oncology to additional areas, including mental health, cardiology, diabetes and infectious disease — including COVID-19.

At the latest event in our *Tales from the Trenches* series, [Paragon Biosciences](https://paragonbiosci.com/) Founder, Chairman and CEO Jeff Aronin joins Eric to discuss his career-long entrepreneurial journey, lessons he’s learned along the way and his vision for the future of Tempus.
