Where Models Break Down
The Model Was Never the Problem. Losing Track of It Was.
One model, ten interpretations
Every team defines 'customer' or 'product' a little differently, and there's no single documented model to settle it.
The diagram and the database disagree
Static Visio files and spreadsheets drift from what's actually running in production the moment they're drawn.
Agents that sound right and aren't
Without a documented model behind them, AI tools answer fluently from whatever context they can find, which is often wrong.
How Ellie Works
From One Model to Everything Downstream
One model, ten interpretations
Model your business, then agree on it
Build conceptual, logical, and physical models in one canvas where business and data teams work together, not in separate tools.

Push it straight to your stack
Generate DDL ,YAML or JSON and send it to Github, Gitlab, or Azure DevOps. What's modeled is what gets built, with no manual re-typing.

Agents that sound right and aren't
Give your AI agents real context
Every model carries AI-specific metadata your agents can read via API, MCP, or YAML, so answers come from your actual data model, not a guess.
