Operator Led

We've built, integrated, and scaled national security businesses from the inside. Our investment decisions are informed by direct operational experience — not spreadsheets alone.

Sector Focus

We invest exclusively in defense, intelligence, real estate, and critical infrastructure. Deep domain knowledge means faster diligence, better underwriting, and stronger post-acquisition performance.

Founder Partnership

We acquire alongside the people who built the business. Our model preserves what works, retains key leadership, and gives founders liquidity without losing control of their legacy.

Mission Alignment

Founder Partnership

Every investment we make strengthens the national security industrial base. We don't chase sectors — we serve one mission, and we build companies that make it stronger.
