A Houston-based investment group has announced three new leadership changes to its organization to start of the new year.

Goose Capital Inc. named Chris Staffel as managing director, along with Jeff Smisek as the firm's president and Jay Collins as chair of the board of directors. The three appointments are effective as of January 1.

Smisek, former chairman, CEO, and president of United Continental Holdings Inc., has been a member investor with Goose but now assumes this leadership role. He serves as president of private investment company Flight Partners Capital, as well as on the board of directors for Finch Therapeutics Group Inc., Lantha Inc., and Molecular Match Inc.

"I look forward to leading Goose Capital as we help early stage companies and their founders develop their products, grow their companies, and create value," says Smisek in a news release.

Collins formerly lead Oceaneering International as CEO and president. He currently serves on the board of directors of the company as well as on the boards of Murphy Oil Company and Pason Systems Inc. Prior to becoming chair of the board of Goose Capital, Collins was its president.

A serial entrepreneur and investor in over 30 startups, Staffel joins Goose to lead day-to-day operations and drive new investment opportunities. She has been a founding member of three startup energy companies with an aggregate exit valuation of $1.38 billion, according to the release, as well as formerly leading Houston-based digital health company, Patients We Share, as COO. Her appointment to the firm follows former director Samantha Lewis's move to Mercury Fund.

"It is an honor to join the team at Goose Capital and work alongside experienced industry leaders," Staffel says in the release. "I look forward to leveraging my entrepreneurial experience to help the start-ups in which we invest, while strategically identifying early stage investment opportunities."

Goose Capital — previously known as The GOOSE Society of Texas — was founded 15 years ago and invests about $10 million per year in early-stage companies. Last summer, the organization rebranded with a new website representing a new phase for the investment group.
