The dirty secret of modern data stacks

Schema contracts are too late and too weak.

Most tools check structure after ingestion. By then the damage is done — pipelines break, dashboards lie, models hallucinate.

You’re still paying teams to clean data that should have been rejected at the gate.

1

Data arrives

POST /ingest/{contract_id} — streaming or batch.

2

Semantic gate fires

Ontology + glossary + business metrics checked instantly. Before any downstream system sees it.

3

Bad data dies here

Rejected in microseconds. Clean data flows. Audit log records everything.

Your real moat
