First front

Critical minerals and sovereign materials.

This is where Stack & State starts because the constraint is concrete. Sovereign technology needs magnets, alloys, graphite, uranium fuel, grid hardware, permitting, processing, and offtake before strategy becomes capacity.

Critical minerals are a first front because they connect policy, engineering, procurement, and capital in one visible bottleneck. The publication expands from here into maritime, energy, dual-use AI, allied industrial capacity, and sovereign infrastructure.

Flagship briefing

The Materials Bottleneck Behind Sovereign Technology

Why processing, not mining, is the real constraint -- and who needs to meet whom to solve it. Covers separation, refining, offtake, and permitting across rare earths, battery minerals, and defense-grade materials.
