Managing Partner
He began his career in 1994 at the Banque de France as a project manager in the Companies Division, where he developed a diagnostic model based on strategic and financial data.
He then moved into mergers and acquisitions, first as a consultant and then in industry (Deloitte & Touche Corporate Finance, SNPE, Roullier). François has been involved in numerous acquisitions, joint ventures and disposals in a wide range of sectors and on all continents. In particular, he was involved in the merger of the European military industries linked to SNPE and the establishment of the Roullier Group in Brazil.

Some fifty SMEs, ETIs and start-ups have chosen his approach of independent advice and intermediation, in their best interests.
Over the course of his assignments, François has built up a flexible working method that enables him to successfully complete the high net worth deals that are entrusted to him. The reputation of his independent team extends to the industrial and service sectors, mid-cap investment funds, private banks, family offices and business angels.
