OPAQUE Systems raised $24 million in Series B funding at a $300 million valuation to advance its Confidential AI platform, addressing what CEO Aaron Fulkerson calls the “trust chasm” blocking enterprise AI adoption. The UC Berkeley RISELab spinout has attracted customers including ServiceNow and Anthropic by providing verifiable privacy guarantees for AI workloads running on sensitive data.

The round reflects growing recognition that traditional security approaches fall short when enterprises attempt to scale AI beyond pilots. According to Gartner, Confidential AI techniques are becoming essential for securing GenAI workflows, while companies like NVIDIA, AMD, Intel, and all major hyperscalers have endorsed the category within the past year.
