Unverified. Ownership and funding are compiled from public reporting as of 2026-05. Unlike the hashes and signatures in this registry, Sovereign Frontier cannot attest any of it, and private-company funding changes faster than this page does. Treat it as a starting point for your own due diligence, not as evidence.
