Corinth Group of Switzerland

Swiss economist based in Chur, Graubünden. Identified by multiple independent complainants across 12+ years as the alleged directing mind behind every iteration of this operation: APAHML, Arcis Consortium, Curatio Capital, Corinth Group, and Three Tuns Investment Holdings. Named in Ripoff Report complaints dating back to March 2014.

Does not appear as a registered director or Person of Significant Control of any entity in any jurisdiction. All registered positions are held by his wife Jurate Kairiene (Swiss AGs), his sons Justinas Kairys (UK SPVs) and Marco Model (Centropa PSC), and his sister Rita Model (C-Capital). Complainants describe Martin as controlling all material decisions while remaining invisible in corporate records.

When clients pressed for proof of funding or questioned delays, complainants report that Martin would shout about “respect” and refuse to provide documentation. No known client has ever been funded. No known fee has ever been voluntarily returned. [Swiss Commercial Register; Ripoff Report #1134964, #1344693; third-party complainant statements]

Sister of Martin Model. Appears in complainant-provided documentation as approving and translating transaction documents on behalf of the Corinth Group. Her involvement in a multi-million-euro cross-border financial operation is notable given that she has no identified financial industry background.

Registered as a signatory of C-Capital Group AG, one of the six Swiss AGs in the Corinth network. Like other family members in registered positions, Rita’s role appears to serve the pattern of keeping Martin Model’s name off corporate records while family members hold formal authority.

The use of a family member with no financial qualifications to approve transaction documents in a purported investment fund structure is, in the author’s assessment, a significant red flag. [Swiss Commercial Register; third-party complainant-provided documentation]

Lithuanian national. Sole signatory (President, individual signature authority) of five of the six Swiss AGs in the Corinth network: Corinth Investment Holdings AG, Corinth Management Services AG, Corinth Capital Markets AG, Corinth Treasury AG, and Rhea Investments AG. Identified as married to Martin Model according to third-party reports.

Jurate holds formal legal authority over every Swiss entity through which complainants’ fees are collected. All six AGs were pre-existing dormant companies acquired and renamed between 2018 and 2025. Despite being the sole registered decision-maker, complainants consistently identify Martin Model – not Jurate – as the person making all material decisions.

The concentration of sole signature authority in one family member – across entities collectively responsible for millions in complainant fees – is, in the author’s assessment, consistent with a structure designed to obscure beneficial ownership. [Swiss Commercial Register; Companies House UK]

Son of Alec Theunissen. Multiple complainants independently identify Brendton as having a direct operational role in client engagement and fee collection within the Corinth Group. Named in client communications as a coordinator who facilitated interactions between complainants and Martin Model.

Unlike his father – who holds formal directorships – Brendton does not appear in any corporate registry filings. His role is known entirely through complainant testimony. Several complainants describe him as increasingly involved in the day-to-day operation, particularly in the collection and processing of advance fees.

The involvement of a second generation of the Theunissen family in the operational side of an alleged advance-fee fraud pattern spanning 12+ years is, in the author’s assessment, a significant indicator of the operation’s entrenchment. [Third-party complainant statements]

Daughter of Martin Model. Identified by complainants as having relocated from Singapore to Switzerland to take up a role within the Corinth Group. Named in Corinth Group internal communications as a member of the Credit Committee – the body that purportedly assesses client applications before fees are collected.

The Credit Committee is referenced in Corinth’s term sheets as the authority approving funding decisions. Complainants report that no client has ever been told they failed the Credit Committee’s assessment – every client who paid was approved, and none were ever funded.

Staffing a credit committee with the directing mind’s daughter – who relocated internationally to join the operation – raises questions about the independence and legitimacy of Corinth’s due diligence process. [Third-party complainant-provided communications]

Son of Martin Model. Sole Person of Significant Control (75%+ ownership) of Centropa Investment Holdings PSC, the UK holding company that sits at the top of the Three Tuns corporate tree. This gives Marco – and through him, the Model family – ultimate beneficial ownership of the UK structure.

Centropa was incorporated in the same batch as other Corinth-linked UK entities, all on 19 May 2019, all registered at the same address. The PSC filing places Marco as the single individual with majority ownership and voting rights over the entity that controls the UK SPVs named as “lenders” in complainants’ contracts.

Marco represents the third generation of the Model family embedded in the corporate structure. His father controls operations; his mother holds all Swiss signatures; his sister sits on the Credit Committee. Every key position is held by a family member. [Companies House, PSC filing]
