What startups should think about when hiring a CFO

The right CFO can (and should) be transformative to a startup. Whether the company is fundraising and expanding, or managing costs to protect the runway, a strong CFO can be the difference between success and failure.

Early on, founders often manage finance themselves. As the business grows, they might appoint a fractional FD to provide specific expertise and start building a more professional finance function.
However, the complexity of financial decision-making increases dramatically as funding rounds become larger, scaling accelerates, and investors start asking harder questions.
The right CFO becomes one of the CEO’s most important partners in building a sustainable, scalable company.
At this point, the role of the CFO shifts from “finance management” to strategic leadership. The right CFO becomes one of the CEO’s most important partners in building a sustainable, scalable company. But, like many C-suite hires, timing and fit matter enormously.
Here are some of the key things startups should think about before making this hire.
Understand the role of a startup CFO
The CFO isn’t simply the most senior finance person in the business. The role is much broader than that, especially in a startup environment. Their responsibilities typically include:
Financial strategy and planning
Managing runway and burn rate
Fundraising preparation and investor relations
Building financial models and forecasting growth
Creating the financial infrastructure needed to scale
A CFO’s job is forward-looking: translating financial data into strategic decisions about where the company should invest and how fast it can grow.
Essentially, they help answer the most important question every startup faces: How do we scale without running out of money?
Timing the hire is crucial
A common challenge for startups is knowing when to hire a CFO.
Bring one in too early and you could be paying a senior executive salary before the company has enough financial complexity to justify it. Conversely, leaving it too late can expose the company to making costly financial mistakes.
There isn’t a single revenue or headcount threshold that works for every startup, but several signals can indicate that it’s the right time:
Preparing for a significant funding round
Closing a major investment that now needs to be carefully deployed
Financial complexity increasing at pace
Investors asking questions the team cannot answer
Multiple revenue streams or international expansion
The CEO spending too much time on finance rather than growth
In our experience, most companies hire a full-time CFO as they approach Series A or Series B. The key is recognising when financial leadership becomes a strategic capability rather than an operational task.
The CFO–CEO partnership is critical
The relationship between the CFO and CEO is central to a company’s success. A strong CFO should become:
A trusted strategic sounding board
A counterbalance to overly optimistic growth plans
A translator between financial realities and strategic ambition
Startups often operate in a culture of rapid growth and experimentation. The CFO’s role is to bring financial discipline without slowing innovation.
It’s a balance that requires trust, alignment, and strong communication. The very best CFOs are not just financial operators — they are strategic partners to the CEO.

Look for strategic thinking, not just financial credentials
Technical financial expertise is essential, but it’s rarely what separates good startup CFOs from great ones. In high-growth companies, CFOs must operate at the intersection of finance, strategy, and operations.
In practice, that means helping leadership teams think through questions, like:
Should we prioritise growth or profitability?
How aggressively should we hire?
How much runway do we need before the next fundraise?
Which markets should we expand into?
The right hire should be comfortable influencing strategy and making decisions (sometimes with incomplete data).
Fundraising experience matters
For venture-backed companies, one of the CFO’s most important responsibilities is supporting fundraising. At some stage, they will likely need to:
Build credible financial models
Prepare investor materials
Manage financial due diligence
Structure deals and negotiate terms
A CFO who has been through multiple funding rounds brings valuable pattern recognition. They know what investors expect to see, what questions will arise during diligence, and how to present financial performance in a way that builds confidence.
That experience can significantly improve the efficiency and outcome of a fundraise.
Hire the right CFO for the company’s stage
The skills required from a CFO change significantly as a company grows. At earlier stages, the role tends to be highly hands-on: building models, establishing reporting systems, and managing cash flow.
As the company scales, the role becomes more strategic, involving:
Investor relations
Capital markets strategy
Building finance teams and systems
Supporting international expansion
Preparing for bigger funding rounds and/or exits
In many startups, the first CFO spends a large portion of their time building the financial foundations the company needs to scale. It is, therefore, important to hire someone who is comfortable operating in a highly ambiguous, fast-moving environment.
Ideally, they will have experience of taking a company through the growth phase the startup is now embarking on, bringing valuable knowledge of the challenges, opportunities and constraints of scaling at that stage.

Don’t overlook cultural fit
While technical skills are easier to assess, cultural fit is an important success factor for CFO hires. The best startup CFOs typically combine:
Financial discipline
Commercial awareness
Pragmatism and adaptability
Strong communication skills
They must also be able to challenge founders constructively — raising financial concerns without slowing the momentum that drives startup growth. In practice, the most effective CFOs are those who understand the balance between ambition and sustainability.
Final Thought
Hiring a CFO is not just a means of bringing in financial expertise. It’s about bringing strategic financial leadership into the company when growth decisions start to carry real make-or-break consequences.
The best CFOs help founders answer the hardest questions:
How fast should we grow?
How much risk can we take?
What does sustainable scale actually look like?
For startups navigating rapid growth and investor expectations, those answers can make the difference between building a great company and running out of runway.
