About Gersende

Experienced financial executive, I support SMEs, mid-market, and growing companies in their management, financing, digitalization (integrating AI), transformation, and sustainable performance challenges by balancing financial performance, operational excellence, and long-term value creation.

With over 25 years of experience in audit, financial management, and organizational transformation, I now act as an outsourced CFO to provide executives with high-level financial expertise, without the immediate need to hire a full-time financial director.

I help companies to:

✔ Structure their finance function and management tools
✔ Secure their cash flow and improve their profitability
✔ Implement relevant reporting and performance indicators
✔ Support financing needs, growth phases, acquisitions, transformations, or internationalization
✔ Strengthen governance and risk management
✔ Integrate CSR and sustainable performance issues into corporate strategy

My background has allowed me to work in various environments: SMEs, mid-market companies, international groups, real estate, services, asset management, multi-site profit centers, and high-growth organizations.
Among my achievements:
• Support for businesses that have experienced over 50% growth in 2 years
• Implementation of financial and non-financial reporting for executives, investors, and banks
• Refinancing of debt and cash flow optimization
• Management of transformation projects, digitalization, and ERP deployment
. Migration to a Shared Service Center (SSC)
• Obtaining and renewal of ISO 9001 and 14001 certifications
• Structuring of international organizations and change management

My conviction: a high-performing finance department should inform decisions, secure development, and contribute sustainably to value creation.
