About Théodore

Fractional CFO for SMEs and mid-sized companies. I step in when you need rigorous financial control — without the cost and complexity of a full-time CFO hire.
I built Fintusk, an AI-powered financial analysis engine that reads your accounting data in minutes and delivers a full diagnostic in 48 hours. What others take 2 weeks to produce, I deliver in 2 days — with the depth of analysis you'd expect from a top-tier firm.
8 years of industrial financial controlling: TotalEnergies, Sodiaal, Garnier, Atlantem. Sectors: manufacturing, food industry, logistics, professional services. Based in South-West France — available remotely and in person.
