    Eclipse Resources

In 2001, with an investment of $1 million, Army vet Hulburt co-founded Rex Energy, an independent energy outfit he grew into a $300 million company by buying up oil and gas fields before taking it public in 2007. With his brother, he then founded Eclipse, based in State College, Pa., a developer of natural-gas properties in the Appalachian Basin. The firm has 90 employees and an estimated $1 billion valuation — an IPO looks imminent. Downtime: Hulburt has a man cave in his home adorned with memorabilia honoring his two favorite football teams: the Buffalo Bills and the Penn State Nittany Lions.
