Katie Brett
I’m CIMA-qualified with over a decade of senior finance experience, and I now work as a fractional CFO and Finance Director for early-stage founders, pre-seed through Series A. I started FoundrFinance because I kept seeing the same thing. Founders building brilliant products with no real handle on their numbers. No cash flow forecast. No clue how long their runway actually is. Books that haven’t been touched in months. And then fundraising hits and everything becomes a fire drill. Before this, I was Global Head of Finance at Framestore, DNEG, and MPC. Big companies, big budgets, multi-entity, multi-currency, the works. I’ve taken everything I learned doing that at scale and now I bring it to the founders who need it most. I’m not just producing spreadsheets. I sit alongside founders as their finance partner, helping them actually understand what their numbers are telling them and making sure the finances are driving decisions, not just recording them. I can help with: • Cash flow forecasts and runway models. The kind where you actually know how long your money lasts and what happens if things don’t go to plan. • Getting your books investor-ready. QuickBooks setup, reconciliation, cleaning up the mess, and building a monthly review process that keeps things tight. • Financial modelling for fundraising. Valuations, pitch deck financials, scenario planning, and the numbers investors will actually interrogate. • Stepping in as your fractional CFO or FD. Senior finance leadership on a part-time basis, without the full-time salary. • Honest, straight-talking financial guidance. Whether that’s a tricky cash position, prepping for due diligence, or just making sense of where your money is going. Why founders trust me: • I’ve been Global Head of Finance at three of the world’s biggest entertainment and VFX companies. I know what proper financial rigour looks like because I’ve built it at serious scale. • I currently serve as Finance Director for a growing UK software agency, where I’ve built their cash flow forecasting, financial reporting, and investor-readiness from the ground up. • I rebuilt a business valuation from scratch for a cross-border equity deal and caught a critical calculation error that would have materially mispriced the whole transaction. That’s the kind of thing that gets missed when you don’t have a proper finance person in the room. • I build the financial models that founders need to make real decisions. Valuations, forecasts, scenario planning. The stuff that matters when you’re raising or trying to figure out where to put your money. • I built FoundrFinance because this gap shouldn’t exist. Early-stage founders deserve the same quality of financial support that bigger companies take for granted. I’m most valuable when founders are growing fast but don’t have a finance person yet. When the books are a mess and a raise is coming. When cash feels tight and no one’s quite sure why or when someone just needs a senior finance partner who gets what it’s like to be building something from scratch.
