Picture
Willie Costa is Co-Founder and COO of Garrison Fathom. An accomplished engineer with experience in the defense, research, and commercial sectors, he has managed multimillion-dollar contracts and contributed to programs with combined budgets of over $300 million. Beyond aerospace, Willie has excelled as an operations manager in the power transmission industry, leading new product development, implementing lean six sigma strategies, and driving profitability through streamlined operations and increased revenue from returns and repairs.
 
As COO of Garrison Fathom, Willie has worked alongside Co-Founder and CEO Vinh Vuong on transactions totaling over $1.5 billion. He played a crucial role in advancing a public-private partnership in a landmark critical and rare earth minerals project that has played a vital part in advancing the security of the US technological supply chain and an increasingly competitive industry facing pressure from global adversaries. Willie has also advocated for the efficient expansion of 5G infrastructure in the United States, working to attract investments and secure legislative support to ensure the United States remains at the forefront of the critically important technology and connectivity industries. Willie also led the final diligence for a $150 million bid to acquire Remington Arms Company from bankruptcy.
 
Together, Vinh and Willie co-led Garrison Fathom’s first hedge fund, GF-I, which has delivered triple-digit growth since its inception in 2022 thanks to its long-term focus of investing in companies with excellent fundamentals and strategic importance to the U.S. economy. This strategy has allowed GF-I to outperform not only the general market in terms of raw and risk-adjusted returns (including ending 2024 with a Sortino ratio over 4), but delivering higher returns than many other funds as well.
 
Willie currently serves on the advisory board of ARBO AI and is a Board Member of RMS Aerospace.

​He is a proud alumnus of Cal Poly Pomona and Penn State.
