Investors Allege: Roger A. Brunner Swiss Trust Trading Group AG Fraud

Roger A. Brunner caused millions in damages.

Roger André Brunner, born June 4, 1968, last residing as Roger Rambow (Krummackerstrasse 16 and 483, 4622 Egerkingen, No. 16 = residence of ex (?)-partner Katy Rambow). From 2022 to 2024, Brunner raised at least 25 million CHF in investment funds for alleged forestry projects in Latin America and promised unrealistically high returns, partly through loans and partly from the sale of shares in Swiss Trust Trading Group AG (STTG, Hinterbergstrasse 18, CH-6312 Steinhausen). No credible documentation was ever provided. STTG is in liquidation; the bankruptcy petition was dismissed on September 18, 2025, due to lack of assets. Warnings: K-Geld warning on Debtor-Watch  Brunner is stringing along the victims with far-fetched and unsubstantiated “stories.” More in the detailed article.

Also been victimized? Experiences with Brunner? Current observations?

Prior to his new “business” activities in Switzerland before 2022, Roger André Brunner was sentenced to imprisonment in Germany.

Roger A. Brunner’s Companies

According to Brunner, Swiss Trust Trading Group AG (STTG AG) is allegedly “one of the largest agricultural companies in South America and one of the few worldwide that fully neutralizes its CO2 emissions.” The fact is: There is no evidence of a company of the same name in “South America,” nor of the complete neutralization of _CO₂emissions. The Swiss company Swiss Trust Trading Group AG (STTG AG), headquartered at Hinterbergstrasse 18, CH-6312 Steinhausen, is in liquidation; the bankruptcy petition was dismissed on September 18, 2025, due to lack of assets.

In the UK, an STTG Limited is registered at 10 London Mews, Paddington, London W2 1HY. The directors are Roger André Brunner (last identity verification on April 24, 2026!) and Wernli, Eric Pascal (ditto).

Swiss Trust Trading Group (Montenegro) 130 OCTOBER REVOLUTION STREET, PODGORICA, Montenegro, registered since December 21, 2020. The managing directors are MILAN KRNJEVIC and ROGER ANDRE BRUNNER. The owner of the company is ROGER ANDRE BRUNNER. The company appears as “not blocked.”

A “Trust AG” (Paraguay) is also said to be a “member” of Swiss Trust Trading Group AG. Trust AG is reportedly headquartered in Asunción, Paraguay. No documents regarding this have ever been submitted. There is a Swiss Trust AG based in Zurich; it is a financially sound company, but it has nothing to do with Brunner.

Morongy SA, Paraguay, and Morongy AG, Zurich: There is a website with an address in Asunción, Paraguay, which is of limited value, lacking an imprint and any concrete names or facts. The company is listed in the Info Clipper directory. However, no reliable documents, such as an extract from the commercial register, have ever been submitted by the company in Paraguay. Morongy AG, Zurich, is now called Greenfield Partners AG and is headquartered at Hinterbergstrasse 186312 Steinhausen, the same address as STTAG. Brunner served on its board of directors until January 31, 2025. Today, Schneebeli, Joachim Ernst, and Schneider, Remo Reinhold are members of the board of directors.

Perfurturo Group AG: Brunner referred to the website , which is operated by the company HYPERLINK “https://www.perfuturo.com/” Perfurturo Group AG in 6372 Ennetmoos/NW. There is no personnel connection with Brunner.

Inceptum Capital AG, based in St. Gallen: Brunner was listed there in a registry in 2023 as an authorized signatory. The members of the Board of Directors are Dr. Andreas Meier, attorney, and Walter Andreas Farner. There is credible evidence that funds from STTG AG were laundered through Inceptum Capital AG.

Brunner’s Fraud Scheme

From Brunner’s prospectus: “The funds raised through the purchase agreement (referring here to the share purchase agreements with investors, author’s note) will be used for the rapid acquisition of Paraguayan rain-forest. The purchased rain-forest areas will be sold to a consortium of well-known insurance companies (Axa, Munic Re, Swiss Re, Allianz, Lloyds, Helvetia, and Perfuturo Holding). These companies intend to repurchase 200 million hectares of forest over time, and a corresponding contract with a fixed purchase price has been concluded. The insurance company purchasing the forests is thus a guaranteed buyer. For investors, this represents a fixed and secure buyer.”

There is no evidence of such a buyer of forest land. The fact is: Since the promised profit distributions to investors have not been made and STTG is in liquidation, no sales have taken place and were likely never actually intended.

Further from the prospectus: “In addition, a prominent figure among the 300 wealthiest Swiss, Mr. Max Rössler, guarantees the investment with his private fortune amounting to 50 million Swiss francs.” The aforementioned guarantee proved to be worthless or unenforceable.

The share purchase agreements known to us all date from 2024 and involve individuals from France and French-speaking Switzerland. Regarding the promised returns, the information Brunner provided to clients varies: “20% every 2 months,” “50% every 2 months,” “50% after 2 months, which can be reinvested. Later, a company would buy the shares.” It goes without saying that such profit promises are “beyond good and evil” and served solely to lure customers. The amounts invested range from CHF 6,000 to CHF 2 million per customer. Both small private customers, who hoped to easily increase their modest capital, and experienced business customers are affected.

The stock purchase agreements known to us are unlawful. The Brunner contracts contain fractional shares, such as “12.25 shares.” For a small, unlisted Swiss stock corporation, the general rule is that shares are issued only in whole units. Fractional shares, as are common with brokers, are highly unlikely; instead, a low par value is chosen or the number of shares is increased. If a Swiss stock corporation sells its own shares, it may do so only up to a maximum of 20% of the share capital; Brunner has evidently sold more. No resolution by the board of directors regarding the sale is known. Transfer documents (endorsement/transfer) are missing. Entry in the share register is mandatory for registered shares; a share register is not known and is unlikely to exist.

There are indications that Roger A. Brunner made ongoing payments through his companies from the new purchase price payments received until 2024. To whom these payments were made and for what purpose is not yet conclusively known. Possible scenarios include: 1. “Profit payments” to former customers based on earlier fundraising campaigns, i.e., payouts to investors from the investments of new customers (pyramid scheme). 2. Transfer of funds to straw men/women and accomplices to remove them from bankruptcy proceedings (which was also successful).

Brunner leaves behind millions in damages and continues to shamelessly string his creditors along.

According to available information, a sum in the single- to low double-digit millions is likely still under the control of Brunner or his accomplices and straw men/women. Informants report that Brunner is traveling extensively, flying first class, and staying at top-tier hotels.

Roger Brunner has been keeping investors at bay since 2025 with far-fetched and shameless stalling tactics, though he is succeeding in this less and less. This has prompted at least two other clients or client groups, in addition to our client group, to commission a debt collection mandate with another company or to take their own civil legal action.

Here are a few examples of Brunner’s stalling rhetoric:

April 21, 2026….Message from an unnamed sender to Brunner. He forwarded the message to investors, among others: “Hi Roger, we’ve now completed transactions totaling EUR 34 million in Turkey. The remaining 16 million will be finalized next week. In that regard, we’re on the right track, and the lawyer can ramp up his team in Dubai next week. What I’m still waiting for are the settlement agreements to be signed between the company in Dubai and the clients. Those are coming from another lawyer and aren’t available yet. But I’m going to put some pressure on them again.”

“In summary: The money is almost entirely in the accounts in Dubai, but the other lawyer handling the settlement agreements—the so-called STTG assignment and the new Dubai articles of association—has not yet delivered the final product!!”

04/26/25: “…. I picked up the conversation in a Bürki chat. Because the absolute worst-case scenario has happened to me. I left my bag on the train. My whole life was in there. Everything’s gone! I was just barely able to order a replacement SIM card. Not so easy without a passport and ID. Best regards, Roger Brunner (Brunner writes to other recipients that he lost the bag on a train in Switzerland).

05/04/25: “Brunner to …….: FYI. The buyback/settlement agreement was delivered yesterday by the law firm. We’re getting closer to wrapping this up. I forwarded the bank statement as of the end of April from our bank to Roger Bürki. The EUR 50 million has been posted. As I said, the doubters doubt because that’s just what doubters do. But there’s nothing we can do about that now, except let them doubt. Threats of criminal charges have become so rampant that these days anyone threatens to file a criminal complaint if their email isn’t answered within two days.

By the way, Milenko has made me a new offer. I’m going to finalize this with him now so that it’s off the table.

We’re in the home stretch! Of course, it’ll take some time to personally contact 350 customers and negotiate the settlement. I’m not sure how the Dubai team is proceeding—alphabetically, or what?! In any case, those who cooperated will be prioritized. Anyone who still files a claim with the bankruptcy office will be put at the back of the line (in any case, we’ll have to wait and see what the bankruptcy office decides). And those who may have filed criminal charges won’t get anything anyway until the proceedings are concluded. Best regards»

Readers can see for themselves that all these statements are completely unsubstantiated and “fantastical.” A typical “after-the-fact” argument used by scammers is to intimidate those who want to take legal action against them by threatening that they will be put at the back of the line or receive nothing.

Roger A. Brunner’s whereabouts

Brunner keeps his whereabouts secret for obvious reasons and spreads misinformation about them.

We know his movement patterns but, for tactical reasons, only disclose this information partially. For a long time, it appeared that Brunner was avoiding the Schengen Area. There were reports of meetings with him in Montenegro, Dubai, and other locations. Since 2026, this is likely no longer the case.

In commercial register entries, Brunner’s registered address was listed as Mariano Roque Alonso (PY). However, such entries are not verified by the commercial registry offices and are accepted without documentation. There is documented proof of an address from 2025 in Egerkingen, Switzerland.
