There is a moment, usually somewhere north of $3 million in revenue, when a founder feels it: something senior is missing. The instinct is right. The job title they reach for is almost always wrong.
Most founders, feeling that gap, go hire a fractional CFO. The market has spent three years telling them it is the grown-up move. And often it is exactly the wrong hire, or the right hire aimed at the wrong problem.
What a fractional CFO actually owns
A fractional CFO owns the numbers and the model. They build the forecast, run scenario planning, manage cash runway, prepare you for a raise, and translate your financials into decisions a board can act on. They own a deliverable. When you need the work done, the model built, the diligence pack assembled, the fundraise run, that is the seat.
The going rate reflects the scope. Fractional CFO engagements typically run somewhere between roughly $1,250 and $5,000 or more a month, versus a full-time CFO whose base salary starts near $200,000. For a founder who needs financial leadership but not a full-time executive, the math is obvious.
What a strategist owns, and why it is a different seat
A strategist does not own the model. They own the board, the whole game.
A CFO can tell you, precisely, what your gross margin is. A strategist asks why your entity is structured to hand a third of that margin to the IRS, whether the capability draining your margin should be owned or borrowed, and whether the capital you are about to raise is even the right lever versus the tax and partnership levers sitting idle beside it.
The CFO optimizes one lever with rigor. The strategist decides which levers to pull and in what order. Those are not the same job, and the CFO is not trying to do the second one.
The test: which seat is empty?
Ask yourself two questions. One: do I know what needs to happen, and just need it executed? If yes, you need a fractional CFO. Hire one. Two: do I have four smart specialists and still no one who can see how their work fits together? If your tax person, your finance person, and your ops person have never been in the same conversation, you do not have a CFO problem. You have an empty strategist chair, and a CFO will not fill it.
The honest answer for most founders
Many founders past $3 to $5 million need both, in sequence. A strategist to see the whole board and decide which levers matter, and where the work demands it, fractional execution to run a specific lever hard. What they should never do is hire the second while assuming they have solved the first.
If you cannot name who, in your business, is responsible for how tax, capital, partnerships, and systems move together, that is the seat to fill first.
