“ My ambition is to bring value added to my clients and unsure a teamwork with all the stakeholders to garanty the success of the process. „

After an initial experience in audit and consulting at Deloitte, Guillaume joined Eight Advisory in 2012.


After several years within the Transaction Services department, where he led numerous due diligence assignments for private equity funds, Guillaume moved toward financial advisory for companies and creditors in the context of refinancing and debt restructuring operations.

He developed his expertise by working on high-profile transactions such as Orpea, as well as on refinancings for companies of all sizes, supporting his clients through complex financial situations — including distressed sales, covenant resets, and liquidity crises.

Building on these years of experience, Guillaume now contributes to the development of Eight Advisory with a particular focus on refinancing.

Guillaume holds a Master’s degree (Master 2) in Banking and Finance (M2 224) from Université Paris Dauphine.
