Strengthens Executive Leadership Team to Support Growth Strategy
AUSTIN, TX / ACCESS Newswire / April 28, 2025 / Angels Aircraft, an Austin-based aerospace technology and manufacturing company focused on the rapidly growing Unmanned Aerial Systems (UAS) market, today announced the appointment of Sean Stiefel as Chief Strategy Officer.
Mr. Stiefel brings deep investment management and capital markets expertise as the Founder and former CEO of Navy Capital, a consumer-focused hedge fund that managed approximately $400 million at its peak. He has served on the board of GrowGeneration (NASDAQ: GRWG) and played a key role in its early funding and successful Nasdaq debut. Sean began his career at Barclays Capital, later holding investment roles at Millennium Partners and Northwoods Capital Management. He has led multiple funding rounds, managed institutional capital, and worked closely with founders to scale businesses across complex regulatory and capital-intensive sectors.
"I'm excited to welcome Sean to the team," said John Courter, Founder and CEO of Angels Aircraft. "He brings a deep understanding of capital markets and growth strategy at exactly the right moment - as defense is being reshaped by autonomy, scalable manufacturing, and mission-driven innovation. Investors are looking for the next breakout opportunity with real implementation in the defense sector, and Angels is positioned to lead that charge into the future of aerospace technology. Sean will be a key partner in helping us build a company that delivers real capability, at real scale, for the future of American defense."
"I first met John and was introduced to Angels as a prospective investor. But when I saw what Angels was building, I didn't just want to invest - I wanted to help drive John's vision forward," said Sean Stiefel, Chief Strategy Officer of Angels Aircraft. "It's been a dream of mine since I was young to contribute to something meaningful for America, and I believe we're entering a golden age of autonomy and aerospace manufacturing - one that will shape our national standing for decades to come. The opportunity to join John at the ground floor as Angels redefines how airpower is built and scaled is something I'm proud to be part of - and a story I will be proud to tell my kids in the future."
