Collate

Collate is the commercial company behind OpenMetadata, the open-source unified metadata platform and data catalog for data and AI. OpenMetadata provides a single place to discover, govern, observe, and collaborate on data assets — databases, tables, dashboards, pipelines, ML models, topics, containers, and API collections/endpoints — with a JSON-schema-first metadata standard, 90+ ingestion connectors, data quality and profiling, lineage, glossary, and role-based access control. Everything in the product is driven by a comprehensive JWT-authenticated REST API (plus Python and Java SDKs, a `metadata` CLI, webhook change-events, and a hosted MCP server), making the metadata layer fully programmable for humans, AI assistants, and agents. Collate offers a managed, enterprise SaaS edition of OpenMetadata. Backed by CRV and Redpoint Ventures.
