Jason Craig, managing director at Denham Capital Management LP, is today’s Forty Under 40 featured honoree.

Denham backs both upstream and midstream companies working in the Lower 48. The private-equity firm has more than more than $9.8 billion of invested and committed capital across nine fund vehicles.

Jason, who previously worked for Newfield Exploration before joining Denham in 2012, said his goal is to help bring the private-equity provider into what he calls the “post- resource-grab era.”

As the unconventional industry matures, “portfolio company capitalization and organizational designs must change to meet longer, more operationally intensive hold periods,” he said.
