Frequently asked questions.
What types of CFO does Isosceles provide?
Isosceles delivers scalable financial leadership tailored to your exact business stage. Whether you need ongoing strategic oversight on a fractional basis or immediate interim coverage during a transition, we match you with a proven CFO built for your goals.
What’s the difference between a Fractional CFO and a Finance Director (FD)?
At Isosceles, the roles of CFO and Finance Director are closely aligned. Both provide senior financial leadership, overseeing reporting, forecasting and strategic decision-making. The distinction usually reflects business size and complexity: CFOs typically operate within larger or investor-backed organisations, while Finance Directors often support scaling or mid-sized businesses.
Our fractional leaders bring the same blend of operational control and strategic insight, whether called CFO or FD, ensuring your business has the financial direction and expertise it needs to grow confidently.
Do you work with existing accountants and advisers?
Absolutely. Isosceles CFOs work in partnership with your existing accountants, tax specialists, and finance teams to deliver a cohesive strategy. We complement, not replace, your current advisers, ensuring alignment between financial operations and business goals. This collaborative approach is a hallmark of our embedded CFO model.
How quickly can an Isosceles CFO be deployed?
With access to hundreds of vetted CFOs and FDs across the UK, Isosceles can deploy an interim or fractional CFO within days, delivering immediate stability, control and strategy.
Do you only work with tech and investor-backed businesses?
Not at all. While many of our clients operate in technology, life sciences and investor-backed sectors, we also support ambitious businesses in manufacturing, professional services and beyond. Whether your goal is growth, stability, or exit readiness, our CFOs adapt to your sector’s unique needs.
Can Isosceles support post-investment or post-exit integration?
Yes. Many clients retain their CFO post-transaction for continuity, reporting and transition management. Our CFOs can assist with integration planning, performance tracking and new ownership reporting to ensure a smooth handover and continued financial stability after completion.
What’s included in Isosceles' CFO service?
Each engagement is fully tailored, but typically includes: financial leadership of your finance function, management reporting, cashflow forecasting, budgeting, governance improvement and stakeholder liaison. For more complex needs, CFOs also lead due diligence, system upgrades, or finance transformation projects.
How can a Fractional CFO help my business grow?
A fractional CFO gives you access to board-level financial strategy without a full-time cost. They translate numbers into insight, supporting investment decisions, margin improvement and scalable infrastructure. Their leadership can be the difference between steady growth and breakthrough performance.
How do I know if my finance function is ready for change?
If reports are inconsistent, systems feel outdated, or strategic decisions lack reliable data, it’s time to review your finance structure. Our CFOs conduct in-depth diagnostics to assess readiness, identify bottlenecks and create a roadmap for improvement.
What industries and company sizes do you work with?
From early-scale SMEs to mid-market PE portfolio companies, Isosceles supports businesses across technology, life sciences, manufacturing and services. Our flexible model means you can access senior financial leadership for as little or as much as you need, always backed by Dains.
We analyse your operational challenges and financial goals to define the exact executive support your business requires.
