Design-partner preview · v0 is audit-only

Audit your Excel model.

Drop your xlsx. Tieout reads the structure, walks the formula graph, and produces a plain-English audit of what you built — what’s solid, what’s fragile, and what would be safer as a driver.

V0 is audit-only: we don’t rebuild your model for you yet. The automatic rebuild lands in v1.5 once we’ve built confidence from real customer workbooks. Your original file is never modified, stored, or saved.

Nothing is stored. File is parsed in memory and discarded.

What the audit looks for

Archetype classification. Is this sales-led mid-market, PLG, usage-based, marketplace? Confidence score attached, so you know whether to trust it for a rebuild.
Detected structure. Which sheets are revenue build vs expense vs assumptions vs headcount. What the driver tree looks like. Whether actuals are reconciled in.
Broken references. #REF!, #NAME?, #N/A — formulas pointing at deleted cells or unresolved lookups.
Hardcoded values that should be drivers. Numeric literals buried in formulas (rates, multipliers, thresholds). Usually safer as a named driver you can see and edit in one place.
Unused or orphaned sheets. Sheets not referenced by any formula elsewhere. Usually archive tabs that got forgotten.
Suggested improvements. Specific structural changes Tieout would make during a rebuild. You review each line-by-line.
