Anthropic Picks Persona to Verify Claude Users

Starting July 8, Anthropic will verify the identity of flagged Claude accounts with a government ID and a selfie check, and it chose Persona, the SF identity platform that calls itself a Rails-first company, to run the verification.

For Persona ($418M raised, $2B valuation), it lands a month after FedRAMP Moderate authorization: one of the most closely watched AI labs now runs its trust layer on a Ruby company.
