About Alexandre

Do you lead an SME and are you looking for a trusted partner to structure your financial management, secure your cash flow, support your growth, or prepare for a strategic operation?

I act as an outsourced CFO, typically 1 to 2 days a week, to help leaders make better decisions and create sustainable value.

I primarily support SMEs with revenues between €5M and €20M on issues such as:
• Performance management (KPIs, dashboards, budgets, forecasts)
• Cash flow management and financing
• Business plans and financial modeling
• Fundraising and investor relations
• External growth, acquisitions, due diligence, and business transfer
• Structuring and professionalizing the Finance function

Formerly an investment banker at Barclays, then CFO and co-founder of toucanBox, a company developed over 8 years before its sale, I bring a dual experience as an entrepreneur and a financier.

My conviction is that a CFO should not only produce reports. They should be a true right-hand man to the leader, capable of providing strategic vision while remaining very operational.

I prefer long-term collaborations with a limited number of leaders to become a trusted partner, involved in the decisions that sustainably shape their company's performance and value.
