# Atlan — The Context Layer for AI > Atlan is the Context Layer for AI: the governed infrastructure between your data stack and your AI systems. Enterprise AI doesn't fail because of the model — it fails because of missing context. Atlan builds the Enterprise Data Graph, a living metadata foundation that unifies 80+ sources with column-level lineage, and serves that context to every AI agent, workflow, and human that needs it. Trusted by Nasdaq, Autodesk, GitLab, and 500+ enterprise data teams globally.
