Back to original languageAbout Fabien
Are you the CEO or CFO of a scale-up or growing SME?
Your finance processes are no longer keeping up. Your budgets are late and already obsolete. You're managing by instinct due to a lack of reliable dashboards. You're hesitating to hire a CFO at €120K/year without knowing if it's truly what you need.
I solve this problem in 3 to 6 months.
I rebuild the foundations of your finance function: structured budgets, clear processes, actionable dashboards, empowered teams. Without complexity, without overstaffing.
What sets me apart
10 years between large groups (Thales, LVMH) and entrepreneurship. I've managed budgets up to €90M and built a startup from scratch. I know both theory and practice.
I don't sell you a PowerPoint report. I stay until the first measurable results. And I come alone or with 1-2 carefully selected seniors (Tandem Paris), not with an army of juniors.
Types of missions I handle
→ Complete redesign of budget and management cycles
→ Construction of steering dashboards (Power BI, Advanced Excel)
→ Structuring of group reporting and multi-entity consolidation
→ Profitability analysis by product/client/country
→ Transition management on critical projects
→ Finance diagnosis and operational action plan
Concrete deliverables
Operational budget in 4 weeks instead of 3 months
Dashboards actually used by your teams
Documented processes and team training
Real-time visibility on your performance
