FOR FEASIBILITY ANALYSTS

    The what-if machine your spreadsheet wishes it was.

    Move a slider, watch every output recalculate — P&L, monthly cashflow, IRR, sensitivity. Save to a draft revision when it's right, revert when it isn't.

    • All parameters editable with live recalc and delta chips vs draft
    • Solver finds the optimal plan under your funding covenant
    • The AI Operator drafts proposals — you accept with receipts

    From deal brief to IC decision — one workbench

    Every number is a formula, every formula is verified, and every change carries a receipt.

    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, cites the exact cells, and files a proposal. Nothing touches your draft until you accept — every action lands on the audit chain.

    EXPORTS & TRUST

    The workbook your lender opens is the model you built.

    Exports are formula-driven with defined names — open in Excel, change a cell, and the whole model recalculates. A HyperFormula gate re-derives every cell before export; a LibreOffice oracle verifies weekly.

    THE TRUST MACHINERY

    Your Excel export recalculates. We prove it.

    Every workbook is formula-driven — no pasted values. Before it leaves the platform, it passes an independent recalculation gate and a LibreOffice oracle. The worst case we allow: a correct pinned value that doesn't recalculate. Never a wrong formula that does.
