# Typedef

> The trust layer for AI on your enterprise data. A live context layer, compiled from your code, that checks every AI answer and every change before it ships.

Typedef builds AI agents for data engineering teams. Our agents automate complex workflows like impact analysis, root cause debugging, model refactoring, and report reconciliation — tasks that traditionally require hours of manual investigation across multiple tools.

The core innovation is the **data context layer**: a continuously-updated, pre-analyzed understanding of your entire data stack — warehouses, transformation frameworks (dbt, etc.), orchestration pipelines, BI platforms, source systems (Salesforce, Stripe, etc.), and streaming layers (Kafka). This gives agents the system-level context they need to operate reliably.

## Key capabilities

- **End-to-End Impact Analysis**: Trace downstream effects of model changes on reports, metrics, and dashboards before merging code
- **Automated Root Cause Analysis**: Trace data lineage to isolate failing nodes when pipelines break
- **Report Reconciliation**: Compare source reports end-to-end against the BI layer to identify discrepancies
- **Authoring**: Generate layer-by-layer implementation plans with verification steps and risk analysis
- **Semantic Validation**: Compare metric computation logic across models (filter conditions, date handling, grain, aggregation)
- **Agentic Analytics**: Power BI platforms with a continuously updated model of the data stack

## Performance

Agents with the data context layer achieve an 82% task success rate on real-world data engineering tasks, compared to 46% without it. Tested across impact analysis, root cause debugging, and model refactoring.
