Promethium is an enterprise AI data platform that provides the Mantra AI Insights Fabric — a three-layered architecture combining a Universal Query Engine for federated, zero-copy data access across cloud, on-prem, and SaaS sources, a 360° Context Hub powered by a proprietary Insights Context Graph, and a Trust Harness for governance, explainability, and access control. The platform enables business users, analysts, and AI agents to ask questions in natural language and receive trusted, governed answers drawn from all enterprise data in real time, without data movement or coding.
