At IPEM Global Paris 2026, SIO’s Managing Partner Kostis Tselenis spoke in the session How Family Offices Prepare and Deploy Impact Capital, alongside leaders from family offices and private capital. The discussion examined how families translate values into institutional-quality investment strategies through stronger governance, portfolio construction and intergenerational alignment.

Drawing on more than two decades of experience advising family offices and institutional investors, SIO shared why the next phase of impact investing depends less on defining values and more on disciplined manager selection, professional execution and scalable transition economy opportunities delivering competitive market returns. The session concluded with an interactive workshop bringing together family offices, GPs and advisors to exchange practical investment perspectives.
