OPAQUE Secures $24 Million Series B to Scale Confidential AI for Sensitive Enterprise Data

New updates have been reported about OPAQUE.

OPAQUE has raised $24 million in a Series B round led by Walden Catalyst, lifting its total funding to $55.5 million and implying a post-money valuation of about $300 million. The company, which positions itself as the “trust layer” for enterprise AI, will use the capital to accelerate deployment of its Confidential AI platform, aimed at organizations blocked from scaling AI by data leakage, compliance, and governance risks.

OPAQUE’s platform provides cryptographically verifiable guarantees that sensitive data, model weights, and AI agent actions remain private and policy-compliant before, during, and after runtime, addressing a key barrier to moving from AI pilots into production. Backed by strategic investors including Intel Capital, Race Capital, Storm Ventures, Thomvest, and the Advanced Technology Research Council, OPAQUE is expanding into post-quantum security, confidential AI training, and sovereign cloud use cases, positioning itself as critical infrastructure for enterprises, governments, and regulated industries seeking to operationalize AI on proprietary data at scale.
