Our Team

Patrik Schmidle


For the first part of his career Patrik worked in various start-ups, mid-sized, privately-held companies as well as large, publicly-traded companies, primarily in the B2B software and market research industries where client lists included many leading technology companies. He took on as many different roles as possible to learn about all aspects of business, always with the goal becoming an entrepreneur. After being part of six acquisitions as an employee, he was inspired to found CARI Therapeutics after watching a close family member’s struggle with opioids. Since then, he’s been leading a team of clinicians, bio-chemical and electrical engineers on a mission to build a company that will have a positive and lasting impact on the opioid crisis.
