What is Zug Zug?
Warehouse-native master data management — the messy-values-to-one-record layer, self-hosted next to your data.
Zug Zug is master data management, minus the enterprise. Your warehouse fills
with names nobody agrees on — BCG, B.C.G., Boston Consulting Group. Zug Zug
is where a team pins them to one approved record, and keeps the governed
lists — Country, Currency, Partner — that everything downstream depends on.
It runs next to your warehouse, sets up with one command, and it's yours to host.
The shape of it
- Read-only in. Point Zug Zug at a warehouse column with a read-only credential. It scans the distinct values still waiting for a mapping.
- Agreed by a human. The team maps each source value to an approved record in a spreadsheet-fast grid — drafts, review, bulk merge, roles, full audit history.
- Written back to your warehouse. Publishing materializes
dim_<x>/map_<x>tables that whatever reads your warehouse can join directly.
Not entity resolution. Not an app builder.
Curated lists, and the mappings into them — materialized where your warehouse can read them. No probabilistic matching, no golden-record survivorship, no app platform.
