Investment thesis
Tamarack Global concentrates its investing on frontier and hard-technology themes, highlighting defense technology and national security, energy dominance, artificial intelligence applied to the physical world, advanced manufacturing, and the space economy. The firm also references a convergence of venture capital and private equity approaches ('The VC/PE Collision'), suggesting a strategy that blends both models. The homepage organizes its work around these thematic investment areas rather than a single stage or sector, indicating a focus on capital-intensive, strategically significant industries.
