ResFrac Corporation builds the industry's only fully coupled hydraulic fracturing and reservoir simulator, letting energy engineers model the full life of a well - from the first crack in the rock to years of production - in one continuous physics-based simulation. Founded in 2015 by Stanford-trained engineer Mark McClure, the Palo Alto company is used by over 35 operators and 50 institutions worldwide across shale, conventional and enhanced geothermal plays.
Mark McClure is the co-founder and CEO of ResFrac Corporation, a Palo Alto-based company building advanced physics-based simulation software for the energy industry. A Stanford PhD in Energy Resources Engineering, he spent time as an assistant professor at UT Austin before founding ResFrac in 2015. His research on hydraulic fracturing, induced seismicity, and enhanced geothermal systems has earned over 5,800 scholarly citations and an h-index of 38. Under his leadership, ResFrac has grown to serve 60+ exploration and production companies and secured a platform investment from Banneker Partners in 2026. He also advises Fervo Energy on geothermal development.
