Thea Montauti d’Harcourt Lyginos

FOUNDER

Thea Montauti d’Harcourt Lyginos’ approach is marked by intellectual rigor, cultural empathy, and a commitment to diversity and inclusion. Her recent collaborations have explored themes such as ecological transformation, identity politics, and digital aesthetics. She maintains strong ties to both established and experimental art scenes, enabling her to bridge the gap between tradition and innovation, as well as between the local and the global.

Thea has held leadership roles in the private art sector, advising major collectors and foundations across Europe and the U.S., and collaborating closely with institutions, galleries, and artists. She has served as a Strategic Cultural Advisor, helping to shape some of the most respected privately owned contemporary art collections internationally.

Prior to founding L’Appartement, Thea held positions at Sotheby’s, New York, and Gagosian Gallery, Geneva, among others. She has extensive experience in artist development and patron engagement and serves as Vice President of the NextGen Members of the MAMCO museum in Geneva.

She is actively involved on the board of the Fondation d’Harcourt, a non-profit family foundation headquartered in Geneva and established by her great grandmother in 1964. The foundation is dedicated to advancing national and international initiatives and collaborations in the fields of mental health and psychosocial support.
