Is Cornerstone Research legit? 1970 verification report

Cornerstone Research is a recognized professional services firm with a clear digital footprint and established presence in San Francisco. While your public identity is strong, we cannot verify your internal professional standards or legal compliance without documentation. For a consulting firm, clients and AI auditors look for specific proof of professional liability insurance and business registration to move beyond a 'provisional' status. Currently, we can only confirm you exist, not that you are fully insured or licensed for high-stakes consulting.
