// THE PROBLEM

Where time went

The database was fast because it was unusual: a specialized SQL dialect, approximate-count sketches, unsupported joins. Most non-trivial questions went to a small data team and sat 2 to 3 days in the queue, engineers who should have been building the platform answered one-off queries, and off-the-shelf text-to-SQL returned confident wrong numbers with no error at all.

// THE BUILD

What we built with them

LevelUp built for correctness first, with the data team: schema-aware retrieval so the model cannot invent fields, query planning, dialect-correct generation with the sketch and time functions injected, static validation before execution, and execution-guided self-correction bounded to a few attempts. Approximate results are surfaced as estimates. Underneath it, a correctness benchmark scored on execution accuracy, the number almost no text-to-SQL project measures.

Correctness Benchmark

In production with the data team; decisions run on current data instead of on whatever the queue delivered days later.
// How we measured

Execution accuracy on a domain gold set of questions with expected results, tracked with latency and cost; time to answer against the workflow-review baseline.
