About Sacha

Graduated from HEC Paris (Master in Management, specialization X-HEC Entrepreneurs) and an engineer from École Nationale des Ponts et Chaussées and ENS, I combine a solid technical background in Machine Learning and Data Science with expertise in business strategy.

I have held key positions in diverse environments, from innovative startups to leading companies such as Iliad. My experience includes notably the creation and improvement of artificial intelligence algorithms leading to significant efficiency gains (up to +30% in accuracy) and the proactive management of complex financial issues.

An entrepreneur at heart, I co-founded SEVE, an ESG startup where I developed my skills in team management, financial structuring, and product development.

Rigorous, creative, and results-oriented, I am looking for exciting opportunities where I can leverage my hybrid expertise in data science, strategy, and entrepreneurship to accelerate your projects and bring real added value.
