The second brain for your business

Trusted by the best data teams on the planet
âOur idea was to build more than a data catalog. We donât only want to have the tables, the columns, and the documentation, we want to expand our domains to go beyond data literacy.â

Organize your glossary
the way you want
A Term is the fundamental unit of your glossary. It can be a KPI definition, metric formula, or business taxonomy â itâs up to you. The special part? Group collections of Terms into Categories, and create multi-level hierarchies that mimic the way you work.


The connected semantic layer
for your business
In Atlan, the glossary is more than just a dictionary. Itâs an activated knowledge network for your business, where you can create relationships between definitions, metrics, and assets.


Rich documentation for rich context
360° context for every term, category, and glossary




Everyone suggests, you approve
Get rid of tribal knowledge with Requests. Anyone with view access to data can suggest owners, missing terms, or a change to the description. Itâs in your hands to approve.
âWe needed something that could help bridge the gap between publishers and consumers, so we adopted a data catalog. Atlan is the layer that brings a lot of the metadata that publishers provide to the consumers, and itâs where consumers can discover and use the data they need.â

Chief Data Architect, Data Platforms




Pick up where you left off


âEach engineer was answering questions 10 to 20% of their time. And then you multiply that over a certain number of employees across the team, thatâs hundreds of hours per month that youâre losing in terms of productivity. Atlan reduced it really, really significantly.â
