Financial modeling for the age of AI
A spreadsheet that shows its work.
Describe the forecast, budget, or valuation you need, and Vireo's assistant builds it in front of you: a visual pipeline you can audit step by step, not a wall of formulas you have to take on faith. The AI does the building. You stay in charge of the judgment.

A1 · The assistant
The AI builds. You audit.
Tell Vireo what you need and the assistant assembles the model on an open canvas, piece by piece, while you watch. Every step it takes records the prompt that produced it, the reasoning behind it, and when it happened. And you decide how much rope it gets: approve every step, approve only changes, or let it run.

B2 · One model
The sheet and the pipeline are the same data.
Tables store typed columns, and every column is a named range. Drop a table onto the canvas, wire it through transform nodes, and the results come back as live tabs in the workbook. Edit a cell and the whole pipeline re-evaluates.

C3 · Pipelines
Transformations you can point at.
Filter, sort, join, union, pivot, unpivot, group, deduplicate, forecast: 77 building blocks that snap together into a pipeline. When a step breaks, Vireo points at the exact block and says why. No more unwinding nested formulas to find the bad reference.

D4 · Finance
Made for the models you actually run.
Forecast a series, discount cash flows, surface KPI cards, publish a dashboard form. 33 built-in formula functions cover the row-level arithmetic; the pipeline carries the structure. And Vireo reads files the way they really arrive: fiscal quarters in column headers, negatives in parentheses, currency prefixes.

Straight answers
Where your data lives
Files stay local
Workbooks are .tgraph files on your disk. No cloud storage, no account, no sync.
No telemetry
The app doesn't phone home. The only network traffic is assistant requests, and only when you use the assistant.
AI via our API
Assistant requests route through our server to the model provider. What gets sent is spelled out in the privacy policy.
Everything undoable
Every edit lands on the undo stack, including every change the assistant makes.
Now onboarding
Vireo is in private beta.
We're bringing on a small group of testers: people who build forecasts, budgets, or reporting pipelines in spreadsheets today. Testers get a hosted session or an installer, a direct line to the developer, and a real say in what gets built next.
