FitzGerald’s appointment follows a comprehensive search for a visionary and seasoned leader with a strong background in technology and defense, along with a proven track record of driving business growth. The Board and CEO search committee unanimously endorsed the appointment, underscoring FitzGerald’s alignment with Rebellion Defense’s strategic goals.

His proven leadership as our Executive Chair, deep understanding of Rebellion’s people and products, and demonstrated knowledge of the defense market uniquely position him to drive our future growth."

With over 20 years of experience at the intersection of policymaking, technology, and national security, FitzGerald brings a wealth of knowledge garnered through roles at the Pentagon, Congress, and across private industry. His proven track record in business development, fundraising, and strategic vision, as demonstrated during his tenure as a partner at Lupa Systems and mentor to startups, further highlights his ability to drive growth and innovation.

As both an early investor since 2019 and Executive Chair since May 2023, FitzGerald possesses a deep understanding of Rebellion Defense’s core values and growth strategy. Moreover, his trusted reputation among the Board, senior leadership team, and employees guarantees a smooth transition and continued stability within the organization.

In response to his appointment, FitzGerald said, "I am deeply honored to lead Rebellion’s exceptional team. I’ve seen firsthand how Rebellion software empowers our nation’s defense capabilities. I’m excited to build on this foundation and continue working alongside our incredible team to drive our vision forward."

Previously, FitzGerald was the Executive Director – Strategy, Data, and Design in the Pentagon’s Office of the Undersecretary of Defense for Acquisition and Sustainment. In that role, he led the most significant reorganization of defense acquisition since the Goldwater Nichols Act of 1986. FitzGerald has also served as a professional staff member on the Senate Armed Services Committee, ran the Technology and National Security Program at the Center for a New American Security (CNAS), was the founding Managing Director for the North American business of Noetic, and worked in several technology corporations including IBM and Unisys.

FitzGerald succeeds Interim CEO Barry Sowerwine, who steered the company through a strategic restructuring and led a fifty percent increase in annual revenue. Sowerwine will join the Board and continue serving as an advisor for go-to-market strategies.
