I’m Arnaud. CPA, CMA, and Lean Six Sigma Black Belt. Over 15+ years in finance and operations, I have helped teams turn messy data and slow closes into usable workflows and better decisions.
Most finance training is too theoretical or outdated. You learn concepts, then hit spreadsheets, broken handoffs, and politics. The result is busywork and analysis that goes nowhere.
GoFast.Finance is about closing that gap. Starting with Budgeting and Controlling, improving it step by step. The goal is simple: sound foundations, usable frameworks, clear standards.
