External CFO
for your company
Last updated: 13 September 2026
Part-time finance leadership for CEOs and companies backed by PE or VC investors: we connect cash planning, monthly reporting and strategic advice. Accounting and controlling can complement the engagement as needed.
Supported as a CFO service - from unicorns to young growth companies
In brief
nugrow's external CFO takes responsibility for finance leadership and strategic advice on a part-time basis. Accounting and controlling can be added as separate service modules. We agree scope, availability, start date and initial milestones after reviewing your situation. For a temporary finance leadership role with greater time commitment, we offer interim CFO engagements.
Areas: accounting, controlling and reporting, financial and liquidity planning, strategy
Cost: CFO support from EUR 1,800 per day excluding VAT × agreed workload; details on the pricing page
For whom: growing companies with six- to eight-figure revenues, founders and managing directors without an in-house finance lead
Track record: 350 projects, a team of over 15, nugrow GmbH based in Bochum

When is an external CFO the right fit?
An external CFO is the right fit when you need ongoing finance leadership but do not want to fill a full-time position – a model also known as fractional CFO. For a CFO vacancy, a transition after closing or a time-limited task with a high workload, we look at an interim CFO engagement instead.

Why you should complement your finance department with us
Compare the agreed scope with the total cost of an in-house hire. The following scenarios illustrate different starting points; they do not guarantee any particular saving.
Example: in-house hire
- 1 controller, 3 years' experience
- 1 accountant, 5 years' experience
- You handle strategy yourself
- Salary & opportunity costs: 120.000€
- Onboarding 3 months
- Result: Accounting runs, controlling runs & you have an excellent overview of your finances
Example: higher effort
- 1 controller, 5 years' experience
- 1 accountant, 10 years' experience
- You handle strategy yourself – but thought it would be easier
- Salary & opportunity costs: 200.000€
- Onboarding 6-9 months
- Result: Accounting runs unevenly, controlling gives you no overview & you are far too involved operationally
With nugrow
- Controlling by experts
- No key-person risk
- We work with your finance department
- Capacity matched to the agreed need
- Start date and first milestones based on availability and data
- Result: Your accounting runs on our recommended processes, you are involved only strategically and you have a crystal-clear view of your finances and the road ahead

Our founder
As an interim Chief Financial Officer I kept seeing the same thing: many companies neglect their finances - especially when business is going particularly well.
At nugrow, though, we combine experience-based pragmatism, proven strategy and empathetic communication to develop holistic, tailor-made solutions for our clients and to professionalise the finance function so the overview is clear and the finances can grow with the business.
We are hands-on, pragmatic & always solution-oriented. I am one of your CFOs on demand.
