Something happened in the fractional CFO market in 2023 and 2024 that almost no one is talking about honestly: the supply side flooded.
Tech layoffs put thousands of finance professionals on the street. LinkedIn rebrand cycles took two days. The label "fractional CFO" went from a specialist credential to a starter pack. And the market - founders, CEOs, even private equity sponsors - has had no good way to tell the difference.
This article is the diligence framework I would use if I were buying fractional CFO services today. Use it on every provider you talk to. Including us.
The five questions that separate operators from rebrands.
1. How many years have you actually carried the CFO title?
The honest answer for most 2024-vintage fractionals is between zero and three. They were controllers, FP&A leads, or finance directors who got laid off and rebranded. There is nothing wrong with those titles - they are critical functions. They are not the CFO seat.
A real fractional CFO has been in the seat. Has run the close, owned the audit, walked into a board meeting with a defensible forecast, and stood behind capital allocation calls when they did not work. The number to ask for is years actually carrying the CFO title - not "years in finance."
2. How much capital have you actually closed?
A modeled raise is not a closed raise. A pitch deck reviewed is not a term sheet negotiated. Ask for a number, ask what kind of capital (equity, debt, structured), and ask whether they were the principal at the table or the analyst who modeled it.
The fractional market is full of advisors who have never closed a round. If your business is anywhere near a capital event, that gap matters more than any other.
3. Have you actually sat at a closing table?
Exits are where the work gets tested. Diligence, working capital adjustments, escrow negotiations, indemnification language - these are not theoretical. A CFO who has not closed an exit will tell you exit prep is "12 months out." A CFO who has closed exits will tell you it is 24 months out, and explain why.
Ask: how many transactions have you closed, on what side of the table, and what was the realized value of the businesses involved.
4. Are you only doing finance, or do you also operate?
The split between CFO and COO is largely a Fortune 500 artifact. In growth-stage companies, the executive who can hold both seats is more valuable than two separate executives. Ask your fractional how they think about operations. If they treat it as someone else's job, you have your answer.
We package Fractional CFO, Fractional COO, Interim CFO, and Interim COO together at Catalyst because Brian's career braided both seats - and because growth-stage companies almost always need both functions covered, even when the budget says otherwise.
5. What does your two-week onramp produce?
A real fractional CFO can ship a working operating model and a 13-week cash forecast in the first two weeks. If the answer is "we'll spend the first 60 days in discovery," you are paying for advisory, not execution. The discipline of the onramp tells you everything about how the engagement will run after.
What this means for the buyer.
The market correction is coming. As 2024-vintage fractionals deliver their first real engagements, the gap between "CFO label" and "CFO output" will close hard - and a lot of clients will be left with broken finance functions and the bill for two engagements instead of one.
The buyer's defense is the question set above. Ask it of every provider you talk to. We welcome it.
If you would like to test these questions against Catalyst directly, schedule a CFO Call. The first conversation is with Brian, not a sales rep.
The split between CFO and COO is a Fortune 500 artifact. In growth-stage companies, the executive who can hold both seats is more valuable than two separate hires. Here is when, and why.
Most fractional CFOs spend 60+ days in discovery. That is consulting, not finance leadership. Here is the discipline behind Catalyst's two-week onramp - and why the time-to-output gap is the strongest signal of operator-grade work.
