CFO | The 40m to £100m ARR Journey | Mid-Cap PE-Backed SaaS | South West London / Hybrid (3 days)
The Client
A c.£40 million ARR, mid-cap PE-backed SaaS business that has doubled revenue every year for three years and now employs close to 200 people, chasing £50-60 million ARR within the next twelve months. This CFO seat exists because the board wants someone who can own that next leg of growth as a genuine strategic partner, not just report on it.
The Role
This is a chance to build the function fresh. Reporting to the CEO, you will own finance, RevOps, legal and IT as one function, sit at the centre of board and investor conversations, and stay close enough to the business to know what is breaking and why. Priority one is elevating strong but stretched foundations to match triple-digit growth without losing pace or culture.
Key Responsibilities
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
