Calista Direct Investors is the result of my 20+ years of Private Equity investing throughout Europe, with roles at PE/VC funds, family offices and as Head of the LPEA (Luxembourg Private Equity Association) more recently. The common thread throughout my journey has been my passion for entrepreneurship and the potential of private markets to deliver strong, long-term returns to private investors.
Today, as private markets are coming of age, I am proud to bring all my expertise and network to best serve private investors out of Luxembourg, the European hub for PE/VC dealmaking and investing, alongside a team that shares the same values and ethos and brings complementary skills to our clients.

Who we are
Calista’s network of over 300 families and entrepreneurs provides a rich ecosystem for sourcing deals and sharing insights.

Calista is a disrupter in a heavily intermediated market. We sit alongside the families, as an extension of their investment team, working as their partner. As such, our revenues exclusively come from our investors, and we go further, as we co-invest with them when possible, knowing the investment decision rests with them exclusively.” This approach marks a significant departure from traditional investment models, emphasising alignment and transparency with family office clients.
