About Atlan

Atlan is a data catalog and active metadata platform used to discover, understand and govern data across a company. The vendor now presents it as a context layer for AI, meaning it collects knowledge about data and business logic so that both people and AI agents can work with trusted information.

Its main pieces include an enterprise data graph that connects business systems, connectors and apps, data lineage and a data marketplace. Context agents are described as AI teammates that document tacit knowledge, while a context engineering studio helps teams test and ship that understanding. A context lakehouse stores the metadata in open formats such as Iceberg and supports vector search, and the context is made available in tools like Slack, Teams, Claude and ChatGPT.

Atlan is a proprietary commercial SaaS product. The vendor routes pricing questions through its sales team, and it offers live demos and a community hub for users.
