From deal brief to IC decision — one workbench

Model the deal, test the downside, and carry a clear decision record into IC.

THE WORKBENCH

Assumptions on the left. Everything else reacts.

25+ live parameters — pricing, costs, pace, land, financing, tax — with sliders for the big levers. The KPI strip, statements and a full outputs rail recalculate as you drag, with deltas against your saved draft.

THE OPERATOR

An AI analyst that shows its work — and asks permission.

Ask it to stress construction +10% or draft a conservative variant. It runs the real engine and files a proposal for review. Accepted proposals update the draft; saved changes are hash-linked when you save a model revision.

EXPORTS & TRUST

The workbook your lender opens is the model you built.

Supported formula identities are checked before export; failed identities are pinned to correct engine values. XIRR and iterative cells are covered by the LibreOffice oracle.

THE TRUST MACHINERY

Your Excel export is checked before it leaves.

Supported formula identities are checked by the recalculation gate. Failed identities are pinned to correct engine values instead of emitting a wrong formula. XIRR and iterative cells are checked by the LibreOffice oracle; saved model revisions are recorded on the hash-linked audit chain.
