It continuously reads your warehouses, databases, pipelines, BI tools, and business systems to reverse construct an enterprise data graph that captures assets, lineage, entities, metrics, policies, and relationships. On top of that graph, it enriches and curates machine-readable semantics — descriptions, popular joins, KPI and metric definitions, ontologies, and business rules — and organizes them into governed, versioned context repos: bounded bundles of context that reflect how your company defines key concepts and makes decisions. These context repos are then exposed through open interfaces (SQL, APIs, SDKs, OSI/MCP-style protocols) so that agents, copilots, and AI applications can call the same trusted context in real time, rather than each team hard-coding its own logic. Human-on-the-loop governance workflows for conflict resolution, deprecation, feedback, and certification keep that context trustworthy as the business, data, and models evolve.",

[context](https://atlan.com/context-26/?utm_source=atlan_website&utm_medium=easter_egg&utm_campaign=context26&utm_content=h2_missing_context \"Context/26, our community conference\")\n\nWe've spent years studying how enterprises deploy AI agents. The pattern is consistent: teams build impressive prototypes, but hit a wall when moving to production.\n\nThe wall isn't the models. It’s that no agent can reason effectively about a business it doesn't understand — what your data means, how your teams work, how your company defines \"revenue\" compared to the rest of the world.\n\nKey Insight\n\nWhen every organization has access to the same intelligence, **context becomes the differentiator**. The enterprise that best articulates its own knowledge — its data, its processes, its meaning — will build AI that's most useful to its people.\n\n“We built a revenue analysis agent and it couldn't answer one question. We started to realize we were missing this translation layer. We had no way to interpret human language against the structure of the data.”\n\nJoe DosSantos\n\nVP, Enterprise Data & Analytics\n\n![Company logo](https://website-assets.atlan.com/img/home-2026/hp-2026-workday-logo-white.svg)\n\nWatch Video\n\n![Speaker](https://atlan.com/img/home-2026/hp-2026-observation-joe-dossantos-md.webp)\n\nThe AI Context Gap\n\n## One question for AI.\nThree kinds of [context](https://atlan.com/context-26/?utm_source=atlan_website&utm_medium=easter_egg&utm_campaign=context26&utm_content=h2_three_kinds \"Context/26, our community conference\").\n\nThrough our work with enterprises, we've found that even a simple agent task requires three kinds of context — knowledge, expertise, and norms — working together.\n\nTalk-to-Data AgentOperational Agent\n\nWhy is drive-through time up this week?Why is drive-through time up this week?\n\nQuestion It Raises\n\nContext Type\n\nAnswer It Needs\n\nKnowledge\n\nWhat does \"drive-through time\" mean?\n\n**avg\\_dt\\_secs**, not the POS number Finance uses\n\nExpertise\n\nHow do you investigate this?\n\nCheck **seasonality** and nearby launches before naming a cause\n\nNorms\n\nWho's asking, and what can they see?\n\nStore manager sees **their store only**; VP Ops sees the full chain\n\nWhy Customers Love Atlan## The only proven way to create [context](https://atlan.com/context-26/?utm_source=atlan_website&utm_medium=easter_egg&utm_campaign=context26&utm_content=h2_create_context \"Context/26, our community conference\")\n\n1.

You should never be locked into a single vendor's representation of your own knowledge.\n\nFAQ## Frequently asked questions\n\nWhat is Atlan?\n\nAtlan is the context layer for enterprise AI. It sits between your business systems and your AI agents, connecting lineage from data pipelines, business definitions from BI tools and SQL logic, knowledge from SOPs, quality scores, and access policies into a unified context store. Every agent and analyst queries that context store directly — no manual context-building per use case. Gartner named Atlan a Leader in the 2025 Metadata Management and 2026 Data and Analytics Governance Magic Quadrants. Forrester did the same in its 2024 Enterprise Data Catalogs and 2025 Data Governance Solutions Waves. The only platform recognized across all four.\n\nWhat does Atlan do for enterprise AI?\n\nAtlan gives every AI agent the enterprise context it needs: the business definitions behind column names, the lineage behind every output, and the access policies behind every query. Without this, agents hallucinate, misclassify sensitive records, or return answers compliance teams reject. Every AI output is traceable — every answer points back to the data, the definition, and who certified it.\n\nWhat is an enterprise context layer?\n\nAn enterprise context layer sits between your business systems and your AI stack. It unifies context from across the business — lineage, semantic definitions, SOPs, access controls, usage patterns — into a single graph that agents and analysts query in real time. Without one, every new agent deployment starts with months of manual context-building. With one, every new agent inherits the organization's full institutional memory on day one.\n\nHow does the context pipeline work?\n\nFour stages: unify, enrich, certify, activate. Atlan unifies metadata from native connectors — data warehouses, BI tools, pipeline orchestrators like dbt and Airflow. Context Agents auto-generate descriptions, metrics, and business ontology across the full data graph. Human experts review and certify — human-on-the-loop, not out of the loop. Certified context activates to every agent and tool via MCP, SQL, and open APIs. Evals and traces feed back in with each cycle, so context quality compounds over time.\n\nHow does Atlan work with AI agents?\n\nAI agents get enterprise context through Atlan's MCP server, SQL interface, and open APIs. A query returns the data graph, business definitions, lineage, and access policies for that specific task. Context repos version and package this knowledge, so every new agent starts with the organization's full institutional memory instead of a blank slate. No context hardcoded per use case. No starting over.\n\nWhich enterprise systems does Atlan connect to?\n\nAtlan connects natively to 80+ enterprise systems: Snowflake, Databricks, BigQuery, Redshift, dbt, Airflow, Tableau, Looker, Power BI, and Postgres, among others. Once connected, lineage, query history, BI semantics, tags, and quality signals flow in automatically through scheduled and event-based workflows — no manual mapping required. Atlan also layers on top of existing catalogs like Microsoft Purview and Snowflake Horizon, pulling their metadata into a unified context layer.\n\nWho uses Atlan?\n\nAtlan is deployed at enterprises including General Motors, Workday, Nasdaq, Mastercard, and Virgin Media O2. AI leaders use it to give agents governed access to enterprise context. Data engineers automate lineage and discovery. Governance teams enforce policies at the asset level. AI platform teams build and deploy agents faster because business logic is already in the context layer — not scattered across prompt files and wikis.\n\nWhat analyst recognition has Atlan received?\n\nAtlan is the only platform named a Leader in all four major analyst evaluations for metadata and data governance: Gartner's 2025 Metadata Management Magic Quadrant, Gartner's 2026 Data and Analytics Governance Magic Quadrant, Forrester's 2024 Enterprise Data Catalogs Wave, and Forrester's 2025 Data Governance Solutions Wave. No other platform has been recognized across all four.\n\nHow does Atlan work alongside my existing data tools?\n\nAtlan layers on top of your existing data stack. Many enterprises run Atlan alongside Microsoft Purview or Snowflake Horizon or Databricks Unity Catalog — pulling metadata from all into a unified context layer rather than rebuilding from scratch. Built on open APIs and Iceberg-native formats, context stored in Atlan stays portable: it is not locked to any vendor's proprietary schema. Switch AI frameworks, add new systems, or consolidate tools — the context layer moves with you.\n\nHow does Atlan approach context engineering?\n\nContext engineering is the practice of selecting, structuring, and delivering the specific knowledge an AI agent needs at each step of a task. Most teams do this manually for each agent — months of work, duplicated across every use case. Atlan automates it: context from 80+ systems is unified, Context Agents auto-generate descriptions, metrics, and ontology across the full data graph, human experts certify, and certified context activates via MCP, SQL, and APIs. In April 2026, Context Agents generated 690K+ descriptions across 50+ enterprise customers — 87% rated on par or better than human writing. Every eval and trace feeds back in. Context quality compounds with each cycle.\n\nHow do teams get started with Atlan?\n\nStart with a Context Workshop: Atlan's team maps your data and AI architecture, designs a context layer for a priority use case, and sets a measurable baseline. From there, a four-week Context Sprint delivers a working agent and accuracy results you can compare directly against your current approach. Most teams see the first value in weeks.\n\n## Bridge the [context](https://atlan.com/context-26/?utm_source=atlan_website&utm_medium=easter_egg&utm_campaign=context26&utm_content=h2_bridge_gap \"Context/26, our community conference\") gap.\nShip AI that works.\n\n[Book a Demo](https://atlan.com/forms/talk-to-sales-contact/)\n\nSee How it Works\n\n![Trusted by leading enterprises](https://website-assets.atlan.com/img/home-2026/hp-2026-customer-logos-bottom-cta.svg)\n\n\\[Website env: production\\]\n\n{}\n",
