Promethium

Promethium is an open agentic data platform that gives analysts, business users, and AI agents trusted access to all enterprise data through a single governed layer without moving, copying, or consolidating data. Its AI Insights Fabric combines a zero-copy federated Universal Query Engine (Trino) across cloud warehouses, relational databases, SaaS apps and on-prem systems, an Insights Context Graph that assembles business definitions and semantic models, and a Trust Harness that validates answers before delivery. Promethium exposes governed data to any agent, copilot, or application through a single MCP server or REST API, with its Mantra engine powering plain-English agentic analytics. Backed by Insight Partners; led by CEO Prat Moghe.

Promethium publishes 1 API on the APIs.io network. Tagged areas include Company, Data Fabric, Agentic Analytics, Semantic Layer, and Enterprise Data.

Promethium’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 11 more developer resources.
