About
Andrew Kreitz co-founded Castelion in 2022 after running launch forecasting and government cost proposals at SpaceX, where he negotiated multi-billion-dollar contracts with the Department of Defense and NASA. Before SpaceX he spent his early career at Goldman Sachs, where he served as a Vice President executing more than $10 billion in aerospace and defense M&A and capital markets transactions. As CFO he leads Castelion's capital strategy, government cost accounting, and the financial engineering required to scale a hypersonic-weapons production line under DoD acquisition rules. The combination of SpaceX cost proposal discipline and Wall Street deal experience is core to how Castelion books missile contracts at fractions of legacy-prime pricing.
