A graduate of the Master’s in Corporate Finance from the University of Rennes, Guillaume began his career in the financial departments of French and Anglo-Saxon banking institutions (HSBC), where he held roles as Head of Consolidation, Reporting, and then Management Control.
In 2015, he joined KPMG, where he led the Finance Transformation and Performance Management offering for banks as a partner. Later, Guillaume joined Eurogroup Consulting as a partner, co-leading the service offering for CFOs and business functions, supporting them in their efforts to optimize performance and drive digital transformation. He also served as Eurogroup’s CFO.
As a Onepoint partner, Guillaume helps clients implement concrete solutions for process optimization and digitalization tools aimed at managing overall performance (both financial and non-financial). He also supports business and functional teams (IT, HR) in value creation post-deal and ensures financial integration post-acquisition.
I joined Onepoint for its ambition, which goes beyond traditional business and IT consulting. Onepoint strives to cover the entire value chain of a company and play a central role in economic transformation. With our teams dedicated to corporate performance and our culture of excellence, we foster the spread of innovation, best practices, and new knowledge across the economy.
