One report a month, from each source.
Read straight from the vendor on each client’s pull day, matched to the rows it sums into. No warehouse, no export to chase.
For the forecast
Ask the model. 01 / 03
The AI on the numbers a forecast turns on: in Excel for the CFO who keeps the model, on the web for the founder who runs on it. It has read the model, the books, and the call. A figure it cannot point at, it withholds. Nothing changes until a person signs.

01In Excel
On the cell, for the CFO.
Where the model is kept. What moves the answer, the table, the cell and its source, the signature, Review, Chat, and the month. Shot in the pane, on a toy model.
02On the web
On the web, for everyone who runs on it.
The founder, the team, every client a CFO keeps. The numbers against plan, what moved, and a package for the board, from the same record the CFO signs in Excel. Nothing is rebuilt.
Bluebird Coffee and the other companies are a demo practice. Their numbers are made up.
03The month
The month comes to you.
Connect QuickBooks, Xero or Shopify once. On the pull day, Gregory reads one report from each and lines the actuals up against the rows they belong to. Nobody chases the close.
Written only under a rule you signed.
Sign a rule once per source and the month applies on its own, through the same gate as every other change. Without one, it waits for you. A file on a desktop always waits.
What moved, and one way back.
Each month says what was pulled, what was written, and what still waits. Reverse this month puts the prior numbers back, through the gate.
04Why it stays
Why it stays open.
The book stays yours. A number without a source does not land.
On the cell you have open.
Ask there. The answer is the file, the call, or what was signed. It does not take you to another model.
No source, no number.
A figure it cannot point at, it withholds. The gap stays a gap.
You still sign.
Fill can draft where a number came from. The cell changes only when a person decides.
0Writes without you. Nothing applies on its own.
1Path that can change the workbook. It runs through the gate.
A quoteOr the number does not land. Word for word, from the source.
05Connected
Ask from the tools you already open.
The names are the places the work already lives. Gregory connects where a signature has to travel.
Claude
Paste Gregory in as a connector. It reads what is signed, drafts, and proposes. It never approves, signs, or writes the workbook.
ChatGPT
The same door. ChatGPT asks before anything is written into Gregory. The number in the file still waits for you.
Microsoft 365
Excel is the daily surface. A connected account opens the spreadsheets in OneDrive — your files, a folder, a search.
Google Drive
Choose a Sheet in Drive, or the files already picked for that client. Sheets in, Sheets out. Gregory never converts the file.
Excel
The book you already run. Reads, proposes, writes back only through the gate.
The sources
Calls, email, contracts, PDFs, exports, bank statements, chat, your notes. A proposed number has to point at the words it came from.
Data sources
Your data, connected.
Accounting, commerce, distributors, sell-through and trade spend. Their reports are read into the month, and a number from them points at the report it came from.

06Non-negotiables
Enforced in code.
Nothing writes without approval.
The only path that changes a workbook runs through changes a person decided. There is no auto-apply, and no way around the gate.
The workbook stays yours.
What Gregory leaves in the file uses native features — named ranges, notes, a hidden sheet. No macros, and no add-in required to open it.
Excel in, Excel out. Sheets in, Sheets out.
A model lives on one platform for its whole life. Gregory never converts the file into something the client cannot open.
No number without a quote.
A proposed value has to point at the source, word for word. What cannot be grounded is flagged as a gap. Approved changes reach the cell as the number you approved.
Client data stays where the engagement allows.
Per-engagement flags control cloud processing and AI use. Calls send the minimum text needed, and client values never appear in logs.

Live
Gregory is live in the grid.
Fractional CFOs run it in Excel today. The web app opens to a first group of startups now. Either way, you sign, and it never writes a number itself.
For fractional CFOs
Stay in the grid.
The Excel add-in on every client’s book. Stop chasing sources: the month arrives on its own, and nothing writes without you.
