Excel is the model. The model is not the IC record.
Excel runs every PE shop. It also produces broken external references, definition drift between deals, and IC memos that nobody can reconstruct two years later. Capital Refinery sits above Excel — and now feeds it: the Excel Model Bridge exports approved live numbers into your own workbook with provenance columns on every row, a public snapshot-verify URL, and a gate that says whether the workbook is still current. Your model keeps its job. It just can't be the risk system anymore.
What Excel does, what it cannot do.
What Excel does well
Universal modeling and analytical canvas.
Every PE professional models in Excel. Flexibility, formula transparency, instant iteration, no vendor lock-in. There is no replacing the modeling canvas. The team that proposes that conversation has not modeled a deal.
Where Excel breaks at IC scale
The model is the person who last edited it.
Definitions drift between deals. External references break. Assumptions get copied forward from prior transactions. The IC memo summary sits in PowerPoint, the model sits in Excel, and six months later nobody can reconstruct the basis for approval. The polished output makes incomplete diligence look complete.
Where Capital Refinery sits
Above Excel — and one-way into it.
Capital Refinery does not replace Excel. It sits above it — ingests the deal pack, extracts KPIs with source-backed lineage, grades them, anchors the decision — and it feeds Excel through the Model Bridge: a standard tab set you map your own model to once with ordinary XLOOKUPs, then refresh. Every exported number carries where it came from, how it was read, and whether the accounting identities vouch for it. Excel stays. The IC record becomes defensible — and so does the model's data.
Approved numbers flow into your workbook. Nothing flows back.
The bridge is a standard tab set you map to once with ordinary XLOOKUPs. Every exported row carries where it came from, how it was read, and whether the identities vouch for it.
The governed payload — reconciled, reviewed, current.
A crs_… content hash. Verifiable by anyone, no login.
A standard tab set. You map once with XLOOKUP; refresh forever.
Formulas untouched. Capital Refinery never maintains it.
The four accented columns are the part a plain spreadsheet export cannot reproduce — audit-grade provenance one XLOOKUP away from any assumption cell in your own model.
Where the lines fall.
| Capability | Excel | Capital Refinery |
|---|---|---|
| Financial modeling and analytical iteration | Strong — universal canvas | Not the goal — Excel stays |
| Source-backed numbers (every figure clicks back) | Manual cell traces, broken external refs | Yes — candidate trail to source cell |
| Risk Signals graded against firm policy | Manual reconciliation per deal | Yes — observed vs firm threshold, with verdict |
| Lane-aware IC memo from raw deal pack | Built from scratch every deal | Yes — same shape every deal |
| IC anchor on approval | “The version we approved” — file naming convention | Yes — cryptographic snapshot of decision basis |
| Drift tracking after IC | Manual reconstruction quarter to quarter | Yes — “since IC” renders against the anchor |
| LP-verifiable share page | No | Yes — cryptographic fingerprint |
| Audit trail across overrides | Manual versioning of file copies | Yes — every override versioned with basis |
| Approved live numbers refreshed into YOUR model | Copy-paste from PDFs and data rooms | Yes — one-way Excel Model Bridge, mapped once with XLOOKUP |
| Provenance inside the workbook (source · method · verified) | No — a number is a number | Yes — four provenance columns on every exported row |
| “Is this workbook still current?” | File-name archaeology | Yes — deterministic snapshot id + Live Gate: LIVE / WARN / BLOCKED |
The gate answers before you trust the number.
Every exported workbook carries a snapshot id. The Live Gate re-checks it on read — and withholds the claim rather than guessing when it can't vouch for the source.
The snapshot id resolves and every value still reconciles to source. Refresh is a no-op.
The live deal state has moved. The workbook is readable but stale — pull a fresh snapshot before you rely on it.
An identity or attestation no longer resolves. The gate withholds the claim rather than guessing a number.
Keep Excel. Add the decision integrity layer above it — and the bridge into it.
Bring us the same Excel model and source pack you would put in front of IC. Same-day diagnostic pack back — and see the Model Bridge workbook in the Falcon proof pack, generated live from a real deal, publicly verifiable by its snapshot hash.
Keep Excel if you need the universal spreadsheet modeling layer. Use Capital Refinery when you need a neutral, evidence-backed readiness artifact that shows what will survive institutional review.
Capital Refinery is the institutional measurement layer. It does not replace Excel; it sits next to it. The decision to engage is a routing decision, not a swap.
