Workflow
From management call to client-ready model in one flow
Ingest & Map
Drag in your existing Excel workbook or dataroom .zip. Nummo maps sheets, ranges, and dependencies into a structured model, highlighting risks in your DCF, LBO, and scenario logic
Clarify the Ask in English
"Add a downside case with 10% lower revenue across segments and higher OpEx assumptions," or "Build an automated control panel for leverage and exit multiple." Nummo's agents translate queries into validated operations
Automate the Busywork
Use AI to generate new scenarios, refresh comps data, and extract static data into editable cells. The pattern eval engine ensures every change is logically safe and auditable
Review Like an MD
Run an automated model review. Get commentary on drivers, sensitivities, and red flags - across all deliverables - before internal review
Package & Hand Off
Export views for presentation books, or pass a single .nummo file to the next team. Every version, query, and assumption is preserved, with Git-style history and visual diffs
Live Updates Until Signing
As management estimates or market dynamics evolve, update assumptions once and let Nummo propagate changes across scenarios and control panels in seconds
