Canton Graubünden Fraud: Corinth Group Entities in Eastern Switzerland
Canton Graubünden — the largest canton in Switzerland by area — is the registered jurisdiction of all six Corinth Group Swiss AGs. This page documents fraud allegations against entities registered in the canton and provides information on how to report suspected financial crime to Graubünden authorities.
Corinth Group in Canton Graubünden
The Corinth Group's Swiss operations are centred in Chur, the cantonal capital of Graubünden. Six AGs are registered at Stadtgartenweg 6, 7000 Chur, and a seventh related entity — Curatio Holding AG — is registered at Dorfstrasse 40, 8834 Schindellegi (Canton Schwyz) [Swiss Commercial Register / Zefix].
Martin Walter Model, identified by third-party complainants as the directing mind behind the network, is a Chur-based Swiss economist. His wife Jurate Kairiene and sons have residential addresses in the Graubünden municipalities of Seewis im Prättigau and Jenins [Swiss Commercial Register; Companies House UK filings].
Other Graubünden Entities
Beyond the six Corinth AGs, additional entities at Stadtgartenweg 6 include IFA Immobilien- und Finanzanlagen AG (formerly IFA Institut fuer Anti-Aging AG), where Martin Model has served as CEO. Montana AG Treuhand, managed by Matthias Baechler — who served on the Corinth Capital RAIF board in Cyprus — is also associated with the address [Swiss Commercial Register].
Dr. Conrad Weinmann, a director of the Corinth Capital RAIF, has served as president of Geschäftshaus Rätia AG in Davos for over 19 years — another Graubünden connection within the RAIF governance network [Swiss Commercial Register, Geschäftshaus Rätia AG].
Fraud Allegations
Multiple independent complainants have filed fraud reports against individuals and entities based in or connected to Canton Graubünden. The allegations describe a consistent advance-fee pattern where clients are charged substantial upfront fees under engagement contracts promising corporate financing, but no financing materialises and fees are not returned [Ripoff Report #1134964, #1344693; Diebewertung.de].
The earliest publicly documented complaint dates to March 2014, when a Frankfurt-based complainant described advance-fee collection under the Curatio Capital brand — the predecessor to Corinth Group. The most recent documented complaint activity is from 2024, spanning a period of over 10 years [Ripoff Report records].
Reporting to Graubünden Authorities
The Staatsanwaltschaft Graubünden (Graubünden Public Prosecutor's Office) handles criminal complaints for the canton. Fraud is prosecuted under Art. 146 of the Swiss Criminal Code (Schweizerisches Strafgesetzbuch, StGB). Filing a Strafanzeige is free of charge. The Kantonspolizei Graubünden can also accept reports. For matters involving potential market manipulation or unauthorised financial services, FINMA should be notified separately.
