Senior finance leadership, with AI on the work, without a full-time hire.
Finance is not keeping up with the business.
Companies look for a fractional CFO for a lot of reasons. The numbers are not trusted, or they arrive too late to use. Cash is this morning's bank balance. Growth has outrun the finance team. A new product is launching with no model. There is revenue in the existing customer base that nobody has captured. Margin is hard to find.
Board, bank, or investor reporting takes a week to pull together. A full-time CFO is not justified yet, but the gap is visible. Multi-entity or post-acquisition work has made the books harder, not clearer.
The common thread is the same. Finance is not keeping up with the business.
Illustrative. The split varies by business — the direction of the change does not.
The fractional CFO, with AI on the work.
We come in as the fractional CFO. The work includes close, cash, and reporting, launching new products, and finding incremental revenue in the existing customer base. AI is how that work gets delivered. Typically the bookkeeper or controller stays.

The three rules that don't move
These three do not move.
Every figure traces to a source record.
If a number can't be tied back, it isn't produced — not flagged, not produced. A plausible wrong number is more dangerous than one that fails loudly.
Nothing posts to the ledger unreviewed.
Agents propose journal entries with the calculation and support attached. A person posts them. Every time, including the routine ones.
A person signs anything that leaves the building.
Board commentary, lender packages, investor reporting. The system drafts. I own it. That is the design, not a transitional arrangement.
Agents we've built. This is the result.
These agents increase revenue, reduce manual work, automate reporting, watch costs, support sales with calculators, and run FP&A. They are not five products. They are how the fractional CFO work gets done, on your data, under review.
Month-End Close Agent
What is holding up the close, and how much can finish without my team touching it?
Works accruals, reconciliations and journal entries, and knows the state of the close at any hour — what is open, what is blocking, and on whom. The controller keeps every judgment call.
Cashflow Agent
Who owes us, which invoices are about to slip, and what have we done about it?
Maps AR by client and invoice, flags what is at risk, and tracks follow-up. Every figure ties to a datapoint you can trace, not a summary assembled the morning it was asked for.
Expense Agent
Which costs are trending up, and which ones need my attention?
Runs cost lines month over month and pairs each movement with the reason it moved. Trend and cause in one pass.
Flux Analysis Agent
What changed in the P&L, why, and is it a problem?
Produces variance with the explanation attached rather than a column of deltas. Corrections are captured, so next month's narrative is better than this month's.
Daily Brief Agent
What is on my plate today, and am I walking into every meeting prepared?
Pulls CRM, email, calendar, call transcripts and project trackers into today's priorities and a brief for each meeting on the calendar.
A healthcare and wellness operator, start to finish.
Reporting was pulled by hand. The close ran fifteen days, so performance was reviewed halfway through the following month. There was no forward view of cash — only the bank balance — and no reliable read on which parts of the business were actually profitable.
Reporting dashboards wired to the source. A cash forecast that updates rather than gets rebuilt. AI-driven workflows across the close and reconciliation, with review gates at every point a number leaves the system. Then the chart of accounts cleanup that made all of it possible.
The close moved from fifteen days to three. Manual reporting work fell by roughly sixty percent. KPIs became visible across the business in real time, and cash could be seen weeks ahead instead of at the end of a statement.
Anonymized at the client's request. One engagement — results depend on the state of the books, the systems in place, and how much of the business is willing to change. Not a promise of comparable outcomes.
You talk to the operator.

Stavros Christias has spent a decade in healthcare, SaaS through acquisition, startups, and PE-backed groups — close, cash, and reporting, including a month-end that moved from fifteen days to three.
Vantage Rock is that work with AI on it. When you reach out, you talk to him. Not a sales team.
How involved we are. Not a product list.
Different companies need different depth. These are levels of involvement, not a menu of products. Fees are scoped after we talk.
A lighter cadence. The books exist; finance is not in the decisions yet.

- Monthly review and working session

More time in the work. Cash and forecast need to lead.
Deeper involvement so cash, forecast, and reporting stay current as you grow.
- Two working sessions a month

The questions that come up every time.
A bookkeeper records what happened. A controller makes sure it was recorded correctly and closes the books. A fractional CFO uses that information to help you decide what happens next — pricing, capital, hiring, where margin is actually coming from — on a part-time basis, for companies that need the judgment but not a full-time executive salary.
