Martin Model Scam: A 20-Year Pattern Across Five Corporate Identities

Searches for “Martin Model scam” lead to a two-decade trail of independent complainant allegations against Swiss economist Martin Walter Model. This page traces the pattern through five documented corporate identities and multiple jurisdictions.

Who Is Martin Model?

Martin Walter Model is a Swiss national residing in Chur, Canton of Graubünden. He is listed on the Corinth Group website (corinthinvest.com) as “Senior Advisor / Head of Credit Committee.” Multiple independent complainants and public registry records identify him as the directing mind behind a succession of investment entities that have attracted fraud allegations since at least 2014 [Ripoff Report #1134964; Diebewertung.de; Verbraucherschutzforum Berlin].

The Five Corporate Identities

Third-party reports and registry data document that entities associated with Martin Model have operated under at least five sequential brand names. The earliest referenced identity is APAHML, a Hong Kong entity that was dissolved between May 2021 and June 2022. This was followed by Arcis Consortium, then Curatio Capital (operated jointly with H. Samaras of Pytheas, Cyprus), then the Corinth Group (the current primary brand), and most recently Three Tuns (the UK rebrand commencing 2022–2023). Swiss commercial register records confirm that CCG Curatio Capital Group AG was renamed C - Capital Group AG in April 2025 [Zefix, CHE-108.684.891], and Companies House records show systematic Corinth-to-Three Tuns name changes across UK entities [Companies House, UK, 2022–2023].

The Advance-Fee Pattern Complainants Describe

Across all five identities, complainants describe a remarkably consistent sequence. Prospective clients are approached through intermediaries or direct contact and offered access to institutional investment financing for their projects. They are invited to Chur, Switzerland, at their own expense, where they meet Model and his team. They then sign a suite of contracts with Corinth entities and pay substantial advance fees — typically EUR 50,000 to EUR 80,000 or more — described as “Cost Contributions” under Article 26 of the standard Corinth contract, which includes a clause promising return of fees if the transaction is not completed. According to complainants, following payment the promised financing never materialises. Instead, clients receive escalating explanations for delays — including, according to multiple complainants, identical excuses referencing Trump tariffs and Bank of America compliance requirements, which complainants describe as factually incorrect [Diebewertung.de; Ripoff Report #1134964 comments]. No complainant has publicly reported receiving either funding or a refund.

Scale of Alleged Losses

The geographic and financial scale of the allegations is substantial. A report on Diebewertung.de describes an Austrian investor alleging losses of approximately EUR 1.5 million. Ripoff Report #1344693 references a group of South African investors. A June 2024 update to Ripoff Report #1134964 by “J. Stark” from the United States states “my company and I are a victim” of the same entities. German victims are referenced in connection with W+ST Corporate Finance of Bad Homburg. The total alleged losses across all known victim groups are estimated at EUR 2.5 million or more.

Dual LinkedIn Profiles

Model maintains two separate LinkedIn profiles under different names: one as “Martin Walter” (associated with the Corinth Group) and another as “Martin Model” (associated with Bioplatin AG, a Maienfeld-based entity). This use of variant names across professional platforms is noted by investigators as consistent with efforts to compartmentalise his online identity [LinkedIn].

Why the Scam Allegations Persist

In the author’s assessment, the persistence of “Martin Model scam” allegations across independent platforms, multiple countries, and more than a decade is explained by several documented factors: the absence of any publicly verifiable completed investment transaction; the sequential cycling through corporate identities when complaints accumulate; the use of family members in all registered positions to avoid personal registry exposure; and the continuation of fee collection even after CySEC revoked the network’s sole regulatory licence in October 2022. Each of these factors is independently verifiable from public records.
