Group FP&A Manager · ICAS Chartered Accountant
Callum Wells
The accountant that builds.
I'm a finance professional who builds. I use AI and code to cut the busywork out of reporting, forecasting, and analysis - turning spreadsheets that take days into tools that run in seconds.
A bit about me
I'm an ICAS Chartered Accountant and First-Class Economics graduate who started out in Big 4 assurance at EY before moving into high-growth FP&A. Today I lead Group FP&A - owning budgets, building the long-range model, and business-partnering with department heads to turn numbers into commercial decisions.
What sets me apart is how I work: I bring traditional financial rigour together with Python, data analysis, and AI-driven automation - implementing Datarails, scripting away manual reporting, and using tools like Claude to get to answers faster.
Outside of work I'm usually running or travelling - I've backpacked across Central and South America, Australia, and New Zealand - and I like following where AI and Bitcoin are heading.
