Jim Thorson - Principal

Jim is Principal of Free Radical Ventures in Denver, CO, and is concurrently a founding partner of Pronghorn Operating, LLC, a private, Denver-based oil and gas operator. 

He earned a Bachelor of Science degree in Geophysical Engineering magna cum laude from the Colorado School of Mines.

Jim spent 12 years with Shell Oil in Houston and New Orleans in exploration, development, and applied technology roles.  After returning to Denver, Jim joined and then founded and grew firms focused on exploration prospect and play generation and execution in the Gulf of Mexico and onshore unconventional plays.

He entered seed-stage energy technology funding as an outgrowth of direct energy investments.  He sees a beneficial parallel between oil and gas exploration and early-stage technology development, with success in each relying on analog calibration, carefully discerning and mitigating uncertainty, and portfolio aggregation for risk reduction. 

Jim enjoys helping foster the overall development of the Denver-area energy tech community.



The greater Denver area is a dynamic place for the development and growth of Energy Tech:

  • 60+ O&G Tech or data firms founded in the Front Range since 2010
  • 20+ longer-established O&G tech or data firms originated locally
  • 12+ successful exits of locally-originated O&G Tech/data firms
