Demonstrates Union Square Advisors’ extensive platform in providing comprehensive advisory services and expertise to next-generation defense companies producing critical, disruptive technologies
On May 15, 2025, Union Square Advisors announced it has served as the exclusive financial advisor to X-Bow Systems (X-Bow), the leading non-traditional producer of advanced manufactured solid rocket motors (SRMs) and hypersonics technologies, in the close of its Series B financing of over $105M.
Lockheed Martin led the strategic portion of this funding round with a significant investment in X-Bow Systems.

This additional investment and our ongoing partnership with Lockheed Martin position us for significant growth. We are expanding our production capacity, accelerating our innovation efforts and strengthening our role as a critical independent supplier within the defense industrial base,” stated Jason Hundley, CEO and Founder of X-Bow Systems.
“We are pleased to continue our investment in X-Bow Systems, a company developing SRM technology that aligns with our strategy to support innovative solutions that enhance our nation’s security. Our follow-on investment in X-Bow Systems underscores Lockheed Martin’s dedication to advancing the aerospace and defense industry,” said Chris Moran, Vice President and General Manager of Lockheed Martin Ventures.
The total Series B round included investment from Razor’s Edge Ventures, Crosslink Capital, Lockheed Martin, Balerion Space Ventures, Boeing Ventures, Bravo Victor Venture Capital, Upsher Management Company, Capital Factory Ventures, Arkenstone Capital and Event Horizon Capital.
