Promethium
Promethium is an AI Insights Fabric for querying and understanding enterprise data wherever it is stored.
What Promethium is
Promethium is an AI Insights Fabric for querying and understanding enterprise data wherever it is stored. Its Universal Query Engine runs queries across distributed cloud, on-premises, and SaaS systems without copying the data, including distributed SQL across Snowflake, Databricks, and Oracle. The 360° Context Hub brings catalogs, BI tools, semantic models, business rules, and tribal knowledge into an Insights Context Graph. Its Trust Harness validates answers against that graph and provides SQL, lineage, reasoning, and source context. It also describes role-based access, row- and column-level controls, and domain policies enforced at query time. Promethium uses a hybrid deployment: a managed cloud control plane and a customer-deployed data plane in a VPC or on-premises environment. The product lists connectors such as PostgreSQL, S3, and Salesforce, plus MCP and REST API access for agents and applications. Pricing is custom and available on request; the maker says costs track performance, not data volume, user counts, or API calls.
