Atlan

Atlan is an enterprise data and AI context platform, which the company calls the context layer for AI. It gathers an organization's metadata, data lineage, business definitions and governance rules into one shared graph, then makes that understanding available to the AI agents and tools the organization runs. The aim is to give agents the meaning behind the data, such as how a company defines a metric like revenue, who is allowed to see what, and how a given investigation is normally carried out. The platform is built from connectors to existing systems of data, a data lineage view, a semantics and ontology layer that maps entities, metrics and relationships, context agents, reusable agent skills, and a Context Engineering Studio for building and testing context. A Context Repo is described as an open and portable way to hand that context to custom agents, vertical agents and general purpose assistants. Data and analytics leaders, governance teams and AI platform teams at large enterprises are the intended buyers, particularly where prototypes stall because agents misread internal data. Atlan does not publish prices. Its pricing page is a contact form that invites visitors to talk to the sales team about their AI context gap, so cost is quoted on request. The company also states that it was named a Leader in the 2025 Gartner Magic Quadrant for Metadata Management Solutions, and it is hosting a Context Conference on October 28.
