About Mardochée

Do you need solid financial steering, but not a full-time CFO. This is exactly what I do.

External CFO since 2021, ESSEC graduate, I work with SMEs and mid-sized companies that need to put their finances in order, structure their reporting, or navigate a pivotal period — without delay.

My approach: I get into the practical details from the first week. No endless scoping phase. I adapt to environments without established processes and produce reliable deliverables alongside the diagnosis.

What I focus on:
• Accounting catch-up and validation
• VAT audit, tax compliance
• Reporting, dashboards, budgets
• Cash flow management
• ODOO, Xero, Sage deployment
• French GAAP, IFRS, Anglo-Saxon accounting standards

25 years of experience. Available immediately.
  • French

    Native or bilingual

  • English

    Fluent

Can work on-site
Courbevoie (up to 10km), Levallois-Perret (up to 10km), Puteaux (up to 10km), Asnières-sur-Seine (up to 10km)
