SGPA

Jean-Paul Guisset established SGPA in 1999 following the sale of JPG. The office functions as the family's permanent investment vehicle and operates without external capital commitments. It concentrates on French companies where the family can hold controlling positions and participate directly in governance. SGPA targets majority investments of €5-30 million in established SMEs and €200,000-2.5 million in startups. Core sectors include digital services to businesses, education and training, and digital commerce. The office has backed companies such as Groupe Proxiteam, Groupe Strada Education and Groupe Lisa Design. It also co-invests with Hexa and Aster Capital in French technology ventures. Activity remains centered in France with occasional exposure to other European markets through portfolio companies. The team comprises 15 professionals including investment directors, operating partners and family-office staff. Alexandre Rayne serves as Directeur Général Délégué. Dimitri Cromback joined as head of the investment team in November 2024. SGPA maintains its headquarters at 122 Avenue Charles de Gaulle in Neuilly-sur-Seine and holds additional commercial properties in the same municipality. SGPA's structure integrates investment decisions with operational management of controlled companies. Family members hold line-management roles inside portfolio groups while external partners run day-to-day operations. This hybrid model allows direct influence over strategy and capital allocation without reliance on third-party fund vehicles.
