You use Claude on spreadsheets. You know the limits — it drifts on formulas, forgets between sessions, burns tokens on grids. Layerz holds the structure so Claude doesn't have to.

I ran it as a dry-run, so the saved model is untouched. Here's the Q1 impact:
Save as scenario_churn_4% and stress a downside?
Scenario saved. The downside cuts deeper:
Covenant breaks at month 9. Want me to surface a debt restructuring option, or just flag it on the board pack?
Quarterly EBITDA, both scenarios:
The downside sits under the covenant floor from Q1 onward.
Done. Board pack ready:
Standard Excel, no Layerz account needed on their end.
Live demo · Layerz answers Claude in real time
“Claude in Excel is awesome for a first draft. But the moment I shape it around how we actually operate, rows shift and a formula on the home stretch lands on the wrong cell. Not something I’d ship.”
Modeler, finance consultancy
“Every session I open, I’m re-explaining the same model — the assumptions, the structure, where we left off. I feel like I never finish onboarding it.”
CFO, PE-backed SME
“A few rounds into a real spreadsheet and the conversation is already too long. I cut it into pieces, lose half the context, and end up tracking what changed in my head.”
Associate, transaction advisory
Every item is named. Every formula is traceable. Claude navigates the dependency graph instead of scanning cells.
This is why your agent stops drifting — the model is read, not guessed. Every dependency holds across sessions.
Monthly close, board pack, cash forecast — unchanged for your colleagues. Standard .xlsx, no Layerz account on their end. Your agent stops drifting on the way there.
