John McCormick at Tamarack Global backs what he calls Maniacs on a Mission—visionary founders building generational technology companies where software-defined hardware is reshaping physical industries like defense, aerospace, energy, and manufacturing. He developed an early digital exhaust thesis from his hedge-fund background that led him to seed data-intelligence companies serving finance and the intelligence community, which became the foundation for launching Tamarack Global.

Notable Investments
Tamarack Global is an early-stage deep-tech investor with $211 million in assets under management, focused on dual-use and national security themes including Defense Tech, Space Economy, Energy Dominance through nuclear fission and fusion, and AI applied to the physical world. Unlike most early-stage funds, Tamarack backs very long-duration, capital-intensive companies like nuclear reactors and fusion energy, and positions itself at the intersection of venture-style technology and project finance through what it calls The VC/PE Collision.
