Model Maestro

Your financial model has answers it is not showing you.

Model Maestro does not read your Excel file like a document. It traces the logic inside it. Every formula. Every tab. Every assumption that someone entered as a number rather than built from first principles.

In M&A due diligence, the distinction between a calculated output and a hardcoded guess dressed up to look like one is often the difference between a deal that closes cleanly and one that surfaces a problem six months later.

The problem

Standard AI tools read the surface. The risk lives underneath.

Feed a financial model into most AI tools and they see text — the values in cells, the headings, a summary of what is visible. What they cannot see is how a number was derived: whether a revenue projection was hardcoded or built from a formula chain, whether tab 3 reconciles with tab 11, whether the EBITDA figure is real or a plug.

The VectorSheet Framework

Formula auditing at structural depth.

The VectorSheet Framework is the technical foundation of Model Maestro. It treats a financial model the way an experienced analyst would — as a network of logic, not a collection of numbers.

Traces formula dependencies across multiple sheets and tabs.

Identifies hardcoded values in cells that should be formula-driven.

Detects breaks in logical consistency between connected sections.

Compresses large, complex files without losing structural fidelity.

Surfaces the full logic chain behind any output — not just the output itself.

What Model Maestro finds that manual review misses.

01Plug Detection

Entered, not derived.

Revenue projections. Cost assumptions. Working capital figures. Model Maestro flags every instance where a number has been entered directly rather than derived — and shows you where it sits in the logic chain.

02Multi-Sheet Tracing

Logic across every tab.

A real acquisition model spans 15, 20, sometimes 30 tabs. Model Maestro follows the logic across all of them, mapping dependencies and flagging where the chain breaks.

03Large Files

Compressed, not truncated.

Enterprise-grade Excel files exceed the context window of standard AI tools. The VectorSheet Framework compresses at scale — the model's structure is preserved, not truncated.

04Audit Trail

Every assumption, traced.

Every flagged item comes with a full trace: where the assumption originated, what it feeds into, and what changes if the number turns out to be wrong.

PE analyst use case

What this looks like in a real deal.

The scenario

A PE analyst is reviewing a target's three-statement model ahead of an LOI. The model spans 22 tabs and the revenue projection shows 18% CAGR for the next five years.

What Model Maestro surfaces

It traces the formula chain behind that 18% figure and finds that three of the five revenue line items are hardcoded — not derived from any underlying volume or pricing assumption.

The model looks sophisticated. The assumptions underneath it are not. This is what Model Maestro surfaces — not a summary of what the model says, but the truth of how it was built.
