About Léonard

**You are at a pivotal moment**: your company generates between €1 and €50 million in revenue, but its development is causing significant friction. Yesterday's processes are cracking under pressure, financial visibility is diminishing precisely when strategic decisions demand it, and AI adoption, while promising, seems complex to implement.


As an **Entrepreneur Co-Pilot**, I bring 15 years of operational experience and an integrated strategic vision to transform these obstacles into competitive advantages. My unique, grounded approach relies on the synergy of 3 key expertise areas, forged in the field:



**Experienced Entrepreneur**: After co-founding and growing a LegalTech company from €0 to €3 million (Demander Justice) and leading a complex restructuring (Groupe Concorde), I understand the concrete challenges of growth: strategic decisions under pressure, team structuring, and the need for reliable data.



**Pragmatic AI Architect**: My experience in designing SaaS solutions based on Machine Learning (Together.do) allows me to bridge the gap between technological potential and concrete applications that create real business value, far from fleeting trends.



**Strategic Financial Leader**: As the first employee and former CFO of Qwant, I led fundraising rounds, structured governance, and learned to extract clear signals from complex data to drive performance and correct economic inefficiencies.

My Strategic Added Value: The Integrated Approach.

The difference between going fast and truly accelerating lies in integrating strategic dimensions. Growth challenges are not solved in silos. I analyze financial problems from their operational and technological angles. This cross-functional vision reveals often invisible connections and transforms major obstacles into concrete, actionable levers for improvement with high ROI impact.
