Welcome to FinTelegram’s Investigative Dossier on the expanding network of individuals, companies, and offshore entities linked to the collapse of Rene Benko’s Signa Group—one of Europe’s largest real estate failures.
This page is dedicated to systematically documenting the actors and organizations involved in or connected to the Signa ecosystem, including those associated with Benko’s private foundations, late-stage capital flows, and opaque advisory structures.
The table below outlines key roles, affiliations, and interconnections—from high-profile investors like Arthur Eugster and Ernst Tanner, to shadow players such as Robert Schimanko, Thomas Limberger, and Moshe Buller, who appear across SilverArrow Capital, Pluto Fund, and World Economic Council (WEC) networks. These names also appear in connection with previous financial scandals, including Madoff, the Manhattan Investment Fund, and controversial offshore structures.
As the legal and financial investigations unfold across Austria, Switzerland, Germany, and beyond, FinTelegram will update this dossier in real-time. The aim is to bring transparency to a network that has operated for too long behind closed doors.
