We founded The Twentieth after working in the arts for over two decades with museums and institutions and as independent philanthropy advisors. 


We share the conviction that engaging with the arts should be an enjoyable, thoughtful and rewarding journey. And we believe in providing unbiased and transparent guidance in an art world that can sometimes be complex to navigate.


With The Twentieth, we aim at helping individuals and corporations build authentic, meaningful, and long-lasting connections with the arts, whether through philanthropy, collecting, or both. 


We chose a name that resonated with our vision: in Hellenistic philosophy, the Twentieth is a concept that celebrates the sense of connection through culture, and the good life. And that’s what we are all about: encouraging connections with the arts whilst making an impact and, above all, enjoying the journey.
