The CFO left this £40m fintech after six months because the role was mis-scoped at the point of hire, not because the individual was weak. The board hired a scaling and fundraising CFO for a business that actually needed a control and reporting CFO first, and the mismatch surfaced within two quarters.
This is an anonymised account of a real pattern we see often. The numbers and details have been changed, but the mechanics are exact. If you are a founder, chair or PE operating partner about to run a CFO search, this is the failure mode to plan around.
What was the business, and why did it hire a CFO?
The company was a UK payments fintech at roughly £40m revenue, backed by a growth equity fund two years into the hold. It had raised a Series B, had a strong product, and a founder CEO who had been running finance through a capable but stretched Financial Controller.
The board wanted a CFO for the next raise. The narrative in the room was growth: a Series C in twelve to eighteen months, international expansion, and a finance leader who could tell the equity story to new investors.
So the brief written was a fundraising CFO. Ex-investment banking or ex-plc, polished with institutional investors, comfortable on a roadshow.
What actually went wrong?
The hire was excellent on paper and genuine in person. Former banker, one prior fintech CFO role, articulate, investor ready. The board was delighted at offer stage.
Within the first sixty days, the problem became visible. The month end close was taking fifteen working days. There was no reliable single source of truth for revenue recognition across the payment flows. The board pack was assembled by hand each month and different numbers appeared in different slides.
The new CFO was strong at the investor layer and thin on the operational plumbing underneath it. He had inherited a control environment that needed rebuilding, and rebuilding controls was not the work he had signed up for or was best at.
Two quarters in, the friction was constant. The CEO wanted forecasts and a fundraising deck. The CFO wanted three more finance hires and six months to fix the ledger before he would put his name to any numbers going to investors. Both were right. Neither could get what they needed from the other.
The CFO left by mutual agreement at month six. There was no drama, just a quiet acknowledgement that the fit was wrong.
Whose fault was it, really?
It was the brief, not the person. The board diagnosed the need it wanted to have rather than the need it had.
A £40m fintech going into a Series C needs clean, defensible, investor grade numbers first. You cannot fundraise credibly on a ledger that closes in fifteen days and disagrees with itself. The sequencing was backwards. Control and reporting had to come before story.
The second error was interviewing for the exciting part of the job. Every conversation focused on the raise, the vision, the investor relationships. Almost no one pressure tested how the candidate would fix a broken close, build a reporting cadence, or hire and manage a small team under real time pressure.
Candidates answer the questions you ask. If you only ask about the glamorous 20 per cent of the role, you learn nothing about the 80 per cent they will actually spend their time on.
What did the board do next?
The board did three things well on the second attempt.
First, it re-scoped the role honestly. It defined the first twelve months as stabilise and control, then build the fundraising narrative from clean foundations. The title stayed CFO, but the priority order was written down and agreed.
Second, it changed the interview. Candidates were asked to walk through a real close problem and a real revenue recognition question. References were taken specifically on operational delivery, not just on presence and polish.
Third, it accepted a different profile. The successful second hire was a CFO with a controllership backbone who had also done one raise. Less dazzling in the room, far stronger where the business was actually bleeding.
That CFO is still in seat. The close is now at five days, the board pack is automated, and the Series C narrative is being built on numbers people trust.
What are the lessons for boards hiring a CFO?
Diagnose the finance function before you write the brief. Look at the close timetable, the reporting quality and the team depth. The state of those three things tells you which CFO archetype you actually need.
Sequence matters. A control CFO and a scaling CFO are different animals. Very few people are genuinely excellent at both, and you rarely need both at once. Hire for the next twelve months, not the fantasy eighteen.
Interview the boring 80 per cent. Test candidates on the unglamorous operational work that fills the diary. Charisma at an investor meeting tells you almost nothing about whether month end will improve.
A six month exit is expensive in cash, in momentum and in team morale. Most of that cost is avoidable at the briefing stage. This is exactly the diagnostic work we do before a search at Harper May, and it is why re-scoping a role early saves boards from repeating this exact story.
Common questions
How do we know if we need a control CFO or a scaling CFO?
Look at your close and your reporting. If month end is slow, numbers disagree, or you would hesitate to hand your board pack to a new investor tomorrow, you need control first. Scaling and fundraising CFOs assume clean foundations already exist.
Can one CFO do both control and fundraising?
Some can, over time, but rarely both at full intensity in the same year. Decide which the business needs in the next twelve months and hire for that. You can always add capability underneath as you grow. Live CFO and finance leadership roles are listed at harpermay.com/jobs.
Is a six month CFO exit always a hiring mistake?
Usually it points to a scoping or sequencing error at the board, not a failure of the individual. Before you blame the hire, review the brief you wrote and the questions you asked.
