services / data build & semantic layers

Data models and semantic layers everyone trusts.

We build the transformation and semantic layer that turns raw data into trusted metrics, using dbt and MetricFlow, LookML, SQLMesh or Omni, whichever fits you best.

✦ Ready for the AI era. Semantic layers are what make AI analytics trustworthy: one definition of every metric, for people and for agents.
