Run the company. Ari runs the numbers.
Nobody hired you as CFO. Ari builds your financial model from your actual numbers, keeps it current, and answers the questions that come with running a company.
Helping founders and CEOs at
You can run the company, or you can run the numbers.
Your accountant closes the books and tells you what happened. Everything after that is on you: who to hire, how much to spend, what to tell the board. So the plan lives in a spreadsheet, revenue from Stripe or Shopify, payroll from Gusto, the forecast in a file called FINAL_v7, and every new question means exporting, pasting and checking it all again.
Meet Ari, your personal CFO.
Ask a question. Ari builds the model from your actuals and shows you what changes.
Ari builds the model from your actuals.
Connect your systems or upload the spreadsheet you use today. Ari turns it into one model that stays current, so every question starts where the last one left off.
- Read-only.
- Ari reads your books, payroll and billing. Nothing writes back to them.
- Current every night.
- Connected systems sync nightly, so the model keeps up with the business.
- Traced to the source.
- Open any figure to see its formula and source rows. If Ari can't verify a number, it says so.
Ask Ari what you'd ask a CFO.
What moved this week, and why?
Ari checks your numbers on the schedule you set and sends a summary to Slack or email. Ask why something moved, and it traces the change to the vendors, accounts or customers behind it.

In their own words.
“Ari is a signal that this founder gives a damn and he understands his numbers, because Ari makes you do that.”
“cfo.ai is the truth. If you want to know what the heck your company is spending on and if it is driving to ROI, you owe it to yourself to set this finance agent up for yourself.”
“It is life changing.”
Give Ari a work trial.
Connect your systems or upload your spreadsheet. Then ask the question that's been on your list all week.
What CEOs ask before hiring Ari.
How is Ari different from Claude or Codex?
Claude and Codex can read a spreadsheet and work out an answer, but they rebuild the context from the file each time you ask. Ari works in a model built for agents: connected to your systems, updated every night, with every figure traced to its source. The model is still there for the next question. Prefer to work in Claude or Codex? Connect them to the same model through the cfo.ai MCP server.
I'm not a finance person. Will I follow it?
Yes. Ask in plain words and Ari answers in plain words, with the numbers behind each answer in the model. If a term is unfamiliar, ask Ari what it means.
Do I need a financial model to start?
No. Connect your systems or start with a few assumptions, and Ari builds the model. If you already have a spreadsheet, Ari can rebuild its logic in cfo.ai.
What happens when Ari gets something wrong?
You can see where. The math runs on a deterministic engine, and every figure traces back to its formula and source rows, so a wrong number leads you to the input behind it. Fix the input and the model updates. Every change Ari makes is logged and can be undone.
Do I still need my accountant?
Yes. Ari doesn't close your books; your accountant does. Ari works on top of the closed numbers: the forecast, the scenarios and the questions.
What does it cost?
Startup is $375 a month billed annually, or $500 billed monthly. Every plan starts with a 14-day free trial. See pricing for Growth and Enterprise.
