Confidential AI and Analytics on Encrypted Data

Opaque Systems builds confidential computing infrastructure that allows enterprises to run advanced AI and machine learning workloads on sensitive data while keeping all information encrypted throughout processing. Founded in 2021 and backed by $55.5 million in funding — including a $24 million Series B led Walden Catalyst Ventures in February 2026 — the company focuses on secure analytics, regulated data collaboration, and compliance-grade attestation.

Its platform integrates seamlessly with enterprise workflows via notebooks, REST APIs, and low-code interfaces, providing encrypted computation, real-time monitoring, and automated cryptographic proofs of system behavior.

Opaque’s technology is designed for sectors with stringent data handling requirements, helping organizations meet regulations, such as DORA, while enabling AI development without exposing sensitive information.
