Natural-language access
to data warehouses.
In private beta.
Production-grade NL→SQL for Snowflake. Schema-aware. Audit-clean. Cost-conscious.
Real tools. Real recognition. Honest framing — we ship in these stacks. No partner claims.
Natural language,schema-grounded.
The planner is dbt-manifest-aware, joins-aware, semantic-layer-grounded. Before the model writes a single line of SQL, it narrows the question to the tables an engineer who knew the warehouse would have chosen. Produces SQL a human reviewer would sign off on.

The customer tableproblem.
Real warehouses have customers_v2_final_USE_THIS next to customers_v2_final. Our planner figures out which is canonical before the model sees the question.

Know the costbefore you run it.
Preview cost before execution. Stops the runaway dashboard-spam problem.

One semantic layer.Different SQL dialects.
Snowflake is live in private beta. Databricks is in active build. BigQuery and Redshift on the roadmap. Same semantic layer, every time.

How the planner thinks.
Four layers. Each one is something an engineer who has lived inside a real warehouse would recognize.

How we survive real warehouses.The schema introspection problem.

We work on scoped builds and embedded engineering for ops, finance, and data leaders at mid-market companies. This natural-language warehouse layer is the worked example of how we think about the data layer underneath AI products.
