Companies that use Microsoft 365 GCC High

I noticed that Microsoft 365 GCC High users are overwhelmingly defense-focused companies that either build physical hardware for military applications or provide specialized technical services to government agencies. These aren't typical B2B software companies. They manufacture everything from wire harnesses and propulsion systems to counter-drone technologies and submarine components. Many provide systems engineering, cybersecurity, software development, or mission support directly to the DoD, intelligence community, or NASA. A significant subset operates in aerospace, building satellites, spacecraft components, hypersonic systems, or additive manufacturing for defense applications.

These companies span a wide maturity range, but most appear to be established businesses rather than early-stage startups. The majority have 50-500 employees and have been operating for years or decades without recent venture funding. When funding exists, it's often private equity, grants, or later-stage rounds rather than seed capital. The handful of startups present (like Quantum Space or Unearthly Materials) are Series A or seed stage but still defense-focused.
