After having studied Geopolitics and History at Sorbonne University, then Sociology and Applied Economics at Dauphine University, and finally Finance at SciencesPo, Clarisse embarked on a 10 year long journey in investment banking, from Paris to New York. She has had various roles (research analyst, wealth management, Chief of Staff, export and trade, global coverage, etc.) at Goldman Sachs, BAML, and CA-CIB. She tried to kickstart an ecological payment app but ended up creating the first hydrogen group in French banking history, before leaving for Dfns.

She studied Information Security and Computer Science at Sorbonne Université, before getting her PhD in Cryptography from Ecole Normale Supérieure. She then went on working for Orange and Safran (IDEMIA) as R&D Engineer, became professor and lecturer at University Paris Diderot, Panthéon-Assas, as well as post-doctoral researcher at NTT and Polytechnique University of Hong-Kong. Houda has so far published more than 25 academic papers, of which 3 in post-quantum cryptography.

What they are looking for

A modern tech company once said “no one loves process, they drive talent out”. We strongly disagree. We say that only process can help talent perform beyond imagination and push the boundaries of reality. Civilisation was built on ceremonies, habits, routines, discipline, guidelines and recipes. The Seven Wonders of the World would not have been possible without process. The Roman Empire conquered Europe and initiated globalisation not by mere talent, but by process. We want to work with people who understand this.
