BNP Paribas Fortis and GuiSquare – which has developed a novel digital tool for managing personal and family wealth called PaxFamilia – have formed an agreement under which BNP Paribas Fortis will help finance the product’s development by buying an equity stake, and market the PaxFamilia solution in future to clients of BNP Paribas Fortis Private Banking & Wealth Management.

As part of this private equity transaction, BNP Paribas Fortis is taking a minority stake of just over 25% in GuiSquare. The partnership will enable GuiSquare’s founders and key staff to fulfil their development ambitions, maintain their independence and autonomy with respect to BNP Paribas Fortis, and keep their management team in place. PaxFamilia will continue to be marketed directly to other professional and personal clients in Belgium and abroad.

PaxFamilia was created in 2017 by Guillaume Desclée, Guillaume de Monie and Gaëtane Meurant, and aims to be a genuine “Digital Family Office”. It is the only platform of its kind in the market, and adopts a user-focused approach to wealth-related information, offering users simple tools for managing, monitoring and passing on their wealth. The digital tool allows users to monitor their wealth dynamically, giving a clear, responsive and documented overview of a person or family’s assets, including real estate. It also includes an inventory of gifts, an inheritance simulator and an electronic safe for storing, consulting and sharing documents securely and confidentially. PaxFamilia uses modern technical solutions (via application programming interfaces) that will make it easy to add on a wide range of additional services and information in future.
“This partnership confirms our commitment to developing and significantly improving the client experience through digital technology, but also our strategy of working with innovative young companies in order to offer our clients the most effective tools,” said Stéphane Vermeire, General Manager Private Banking & Wealth Management.

“By joining forces with Belgium’s leading player in private banking and wealth management, we are strengthening PaxFamilia’s long-term prospects and credibility,” added Guillaume Desclée, founder and chief executive of GuiSquare. “The partnership allows us to improve the service we offer to clients, while maintaining our autonomy and independence. We are also excited about the international prospects arising from the relationship."
