The business case for a finance hire rests on risk and capacity, not workload. Scope the role against workload gaps, ROI, risk- management metrics and the obstacles you expect next, and hire for the next 24 months rather than the next 24 weeks.
Scope the role before you cost it
A business case built on a job description is fragile. The process that holds up starts by meeting well before hiring begins to map out objectives, scoping the role against workload gaps, ROI and risk-management success metrics, and the business obstacles you expect next. Those four inputs are the case.
Framed that way the conversation changes. You are not asking for headcount, you are naming what the business currently cannot see and what it costs to keep not seeing it.
The upside deserves a number too. The finance people I place can often pay for their own salary just by getting a decent R&D tax return done properly. That is one line item. The bigger return is harder to put on a slide but more valuable: a good finance leader instils commercial nous and financial literacy across the whole company, and that is what actually drives valuation and growth, more than any question of organisational readiness.
| The weak case | The case that holds up | |
|---|---|---|
| Workload | "The team is busy" | Name the specific gaps: what is not getting done, and what it costs the business that it is not. |
| Risk | Rarely mentioned | What the business cannot currently see, and the consequence when that surfaces in a raise, an audit or a board meeting. |
| Horizon | Scoped to today | Scoped to the next 24 months, so the hire grows into the role instead of needing replacing in a year. |
Hire for the next 24 months, not the next 24 weeks
The most useful framing I give founders is to hire for the next twenty-four months rather than the next twenty-four weeks. The test in an interview is whether a candidate can already describe what the next version of this role looks like, before anyone has forced that conversation on them. Someone who cannot is telling you the ceiling.
That is also the cheaper path. A hire who tops out in a year means running the search again, and the second search costs more than the salary difference would have.
Hiring too late is the common error
Founders worry about hiring too early. In practice the opposite is more common: for Series A startups with $5m to $15m raised, a head of finance is the typical hire, as our first finance hire guide sets out stage by stage, and hiring too late here is one of the most frequent mistakes founders make. The cost of being late is invisible until something breaks in a raise or an audit. It is worth remembering the floor underneath all of this is legal rather than commercial: ASIC requires directors to keep proper records and prevent insolvent trading, and those duties sit with the board whether or not anyone in the business is resourced to discharge them.
The blind spot that forces the hire is specific. When we polled the Story network of founders, CFOs and senior finance professionals for our Q3 2026 State of the Market report, 73% pointed to the gap between cash and profit as the financial reality founders most often miss, more than unit economics, tax and dilution combined. A founder can be profitable on paper and still run out of money. That gap is the business case in one line: the first finance hire exists to hold the distinction between what the business is earning and what it can actually afford to spend, before the gap forces the conversation.[1]
I set out the signals that say the role has arrived, stage by stage.
Put the cost of a mishire in the case
The downside belongs in the business case as much as the upside. The true cost of a bad hire in a startup extends well beyond salary, covering time, attention, momentum and morale, and typically delaying resolution of the underlying problem by another three months. That is why founders are prepared to pay a premium for judgement: the financial and operational cost of the wrong hire is significantly higher than any salary difference, a calculation Alexey Mitko, who built the finance function from scratch at Canva, Koala and Eucalyptus described to me on The CFO Track.
It also argues for structure over heroics. Pair the senior hire with transactional support underneath rather than asking one person to cover both, which is the most common way a well-justified hire still fails.
I set out what that support structure looks like and what each layer costs.
Common questions
How do I justify a finance hire to my board?
Scope it against workload gaps, ROI, risk-management success metrics and the business obstacles you expect next, rather than on headcount or how busy the team feels. That reframes the conversation from asking for a person to naming what the business currently cannot see and what it costs to keep not seeing it.
What level should I hire at?
Hire for the next twenty-four months, not the next twenty-four weeks. Assess whether a candidate can see what the next version of the role looks like before that conversation is forced on them. What you are buying is not just capability today but the capacity to grow into what the role becomes. A hire who tops out in a year means running the search twice.
Is it worse to hire too early or too late?
Too late, in practice. For Series A startups with $5m to $15m raised a head of finance is the typical hire, and hiring too late at that stage is one of the most common mistakes founders make. Nothing shows up on a P&L to warn you, which is the problem: the bill arrives all at once when a raise or an audit exposes what nobody was tracking.
Should the cost of a mishire go in the business case?
Yes, because it is usually the largest number in it. The true cost of a bad hire in a startup extends well beyond salary: time, attention, momentum and morale, plus roughly three months of delay in resolving the underlying problem. That is why founders pay a premium for judgement, since the operational cost of the wrong hire exceeds any salary difference.
