## About

Proventus was founded in 1969 by Robert Weil. The firm operated as an active investment company in European capital markets for nearly five decades before converting to a family-office structure in 2017. It manages assets for the Weil family and the Robert Weil Family Foundation while preserving a record of independent, contrarian positions. The investment approach spans equities in both listed and private companies, fixed income, currencies, and alternatives. Proventus targets special situations and turnaround opportunities, with a history that includes the 1993 acquisition of Aritmos and its Puma brand. Geographic reach covers Europe as the core market plus selective exposure in North America and Asia. The firm maintains a flexible stance toward co-investments with other family offices and long-term partners. Additional vehicles tied to the family include the Magasin III Museum for Contemporary Art in Stockholm and the Robert Weil Family Foundation. No public disclosure exists on current AUM or headcount.
