Capital crosses borders. AI21 Labs operates from Israel, but principal funding also comes from United States. For sovereignty or export-control assessments, the funder jurisdiction can matter as much as the operating one.

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.
