Fractional CFO servicesA CFO,
two days a week.

Most companies don't need a full-time CFO until $30M ARR. Until then, they need someone who has been one — embedded, available, and accountable. That's the engagement.

§ — Fractional CFO FAQFive questions
we hear first.

If yours is not here, book a 30-minute intro call and we will talk it through.

It depends on the cadence you choose: Advisor is one to two days a month, Embedded six to eight, Operator ten to twelve. Our cost comparison sets out typical market rates against the cost of a full-time CFO.

A bookkeeper records what happened and an accountant closes the books and files; a fractional CFO uses those numbers to decide what happens next: the model, the runway, the board pack, the raise. Many clients keep their bookkeeper and add the CFO on top.

Mostly, yes. We work with founders in Europe, the US and Australia across five time zones, and come on site when a board meeting, a raise or a restructuring needs it.

Yes. The Advisor cadence suits teams that already have a controller. Most clients start at Embedded and step down once the finance engine is running.

The engagement is built for that day. The board pack, model, KPI tree and plans are yours and version-controlled, and we hand them over with the context behind them. Most companies don’t need a full-time CFO until around $30M ARR.
