GoDeFi presents itself as a sleek non-custodial DeFi payment-card platform for everyday crypto users. GammaG appears in FinTelegram’s earlier reporting as a Georgian crypto-payment rail surfacing behind offshore-casino deposit flows and in whistleblower material linked to the wider CoinsPaid orbit. A newly visible link between the two schemes is the name Sandra Kübarsepp, who is publicly recorded as the sole director and sole shareholder of GO DEFI CS s.r.o. The overlap is real. But the bigger question remains open: is this merely a personnel coincidence, or part of a broader continuity structure stretching from casino crypto rails into consumer-facing DeFi branding?
Key Findings
- GoDeFi markets a non-custodial Solana-linked payment-card model that promises users direct wallet spending, no top-up, and a DeFi-to-real-world payments bridge.
- Go Defi Corp. is identified as the developer/operator on GoDeFi’s app disclosures, while GO DEFI CS s.r.o. appears to be the Czech paid-services entity.
- Sandra Kübarsepp is publicly listed in Czech company records as the sole managing director and 100% shareholder of GO DEFI CS s.r.o.
- FinTelegram’s prior reporting placed GammaG LLC in Georgia behind a “CoinsPaid” casino deposit flow and described GammaG as a possible continuity rail in the wider CoinsPaid / CryptoProcessing / Dream Finance / SoftSwiss field. FinTelegram also stressed that the evidence showed functional proximity, not yet proven common ownership.
- Georgia requires VASP registration with the National Bank of Georgia, and the NBG has warned the public against using unregistered virtual-asset providers. Based on the public materials reviewed, FinTelegram could not independently verify GammaG’s NBG registration.
Beneficial Owners, Co-Founders, And Funding
A second publicly visible name around the GoDeFi.me scheme is Sergei (Sergey) Burmisov. In GoDefi’s own 12 March 2025 press release, the company identified Sergey Burmisov as “Co-Founder & CTO” and quoted him directly on the product’s non-custodial architecture and user proposition. The same release also said GoDefi had already raised $2 million in an initial seed round and was preparing a second funding round.
The Estonian national Sandra Kübarsepp (aka Sandra Urvak) is publicly listed as the sole director and sole shareholder of GO DEFI CS s.r.o., the Czech entity named in GoDeFi’s paid-services documentation.
Compliance Analysis
GoDeFi: polished DeFi card pitch, thin public accountability
GoDeFi is pitched as “the first true DeFi payment card for everyday life.” The app-store and website materials describe a 100% non-custodial service built around Solana wallets, promising users that they can connect a wallet, complete KYC for card issuance, and spend crypto without surrendering private keys or pre-funding an intermediary balance. The product language is ambitious: spend, borrow, lend, receive, and send — all wrapped in a consumer-fintech user experience.
Publicly, the structure looks split — and the card story looks broken. The app and privacy materials identify Go Defi Corp. as the operator/developer, while the paid-services terms name GO DEFI CS s.r.o. as the subscription counterparty. Those terms still refer to Quicko Sp. z o.o. as the card issuer. But that disclosure appears stale: the Polish regulator KNF revoked Quicko’s licence on 21 January 2026, and Quicko itself said it lost the ability to provide payment services on 3 February 2026.
Yet GoDefi’s live Google Play listing continues to market a payment card from unnamed “licensed banking partners,” even though the app shows only 50+ downloads. That leaves a basic operational question unresolved: who, if anyone, is currently issuing the GoDefi card, and whether the card system works at all.
GammaG: from Georgian crypto rail to FinTelegram’s continuity hypothesis
GammaG entered FinTelegram’s reporting through the payment-rail side, not the DeFi-card side. In December 2025, FinTelegram documented an observed deposit flow at offshore casino Vegadream in which selecting the “CoinsPaid” option opened a GammaG payment pop-up with crypto deposit instructions. GammaG was described there as a Georgia-registered entity offering digital-currency payment solutions, including hosted-wallet and exchange-related functions.

In April 2026, FinTelegram followed with a more pointed thesis: GammaG may have functioned as a shadow or continuity rail in the same operational field as CoinsPaid, CryptoProcessing, Dream Finance, and the wider SoftSwiss ecosystem. That report was careful on the evidentiary boundary. It did not claim proven formal integration. It said the new whistleblower material reinforced the functional closeness already identified by FinTelegram. That distinction matters. A rail can be strategically close, commercially integrated, or operationally interchangeable without the public record yet proving identical ownership.
That is the current state of play. GammaG is not just an isolated Georgian web domain that happened to appear in a single transaction flow. FinTelegram’s existing reporting places it inside a broader compliance pattern: replacement rails, migrating structures, opaque contracting endpoints, and the use of crypto-processing architecture to keep high-risk offshore business moving when older channels become impaired.
The GammaG Connection
Public records and company statements currently tie at least two names to the GoDefi.me scheme: Sandra Kübarsepp/Urvak on the Czech corporate side, and Sergey Burmisov as publicly named co-founder and CTO. GoDefi also claimed in March 2025 that it had raised $2 million in seed funding and was pursuing a second round, although the underlying investors and financing structure have not yet been independently verified.
What FinTelegram can now say with confidence is narrow but important.
We know that Sandra Kübarsepp is publicly listed as the sole director and sole shareholder of GO DEFI CS s.r.o., the Czech entity named in GoDeFi’s paid-services documentation. That is verified. Allegedly, Kübersepp is also a director of the Georgian crypto-payments scheme GammaG. FinTelegram’s prior reporting places GammaG in a CoinsPaid-linked rail environment.
That already makes the overlap noteworthy. A name tied to a consumer-facing DeFi card structure appears in the same investigatory field as a Georgian rail previously surfaced in offshore-casino crypto flows. For compliance professionals, that is enough to justify closer scrutiny.
What FinTelegram knows at this stage
FinTelegram knows that GoDeFi is not just a vague app-store project. It has identifiable entities, a Czech services company, a named control person in Sandra Kübarsepp, and a payments-card narrative built around non-custodial DeFi branding.
FinTelegram also knows that GammaG has already surfaced in FinTelegram’s casino-rail reporting, specifically behind a CoinsPaid deposit path, and later in whistleblower material consistent with a continuity-rail hypothesis.

Those two strands now intersect in a way that is too concrete to ignore and still too incomplete to overstate.
Conclusion
At this point, FinTelegram’s investigation suggests a credible and potentially significant overlap between the GoDeFi scheme and the GammaG scheme. The public record already supports one hard fact: Sandra Kübarsepp, aka Sandra Urvak, controls GO DEFI CS s.r.o., the Czech company behind GoDeFi’s paid-services leg. Separately, FinTelegram’s prior reporting places GammaG inside a suspicious Georgian crypto-rail environment linked to CoinsPaid-branded transaction paths and the broader Dream Finance / SoftSwiss investigatory field.
That is enough to justify continued scrutiny. It is not yet enough to claim full common ownership or a fully proven unified scheme. The overlap is real. The ultimate structure remains unresolved.
Summarizing Table
Here is a compact summary table you can drop into the report.
| Entity | Jurisdiction | Role | Verified connections |
|---|---|---|---|
| Go Defi Corp. www.godefi.me https://app.godefi.me | Delaware, U.S. | App/operator entity shown for GoDeFi | Listed in GoDeFi app disclosures as the developer/operator; app disclosures use the Dover, Delaware registered-agent address. |
| GO DEFI CS s.r.o. | Czech Republic | Czech paid-services / subscription entity for GoDeFi | Named in GoDeFi subscription-plan terms; Czech registry-derived records show Sandra Kübarsepp as sole shareholder and managing director. |
| Sandra Kübarsepp aka Sandra Urvak | Estonia-resident natural person | Control person on the Czech GoDeFi side. According to Estonian register information, she also goes by the name Sandra Urvak. | Public Czech records tie her to GO DEFI CS s.r.o. as sole shareholder and statutory director. |
| Sergei Burmisov | Russia, Montenegro (LinkedIn) | GoDefi CTO and CoFounder | Press release |
| GammaG LLC / GammaG | Georgia | Crypto-payment / exchange-style rail appearing in FinTelegram’s casino-rail reporting | FinTelegram documented a deposit path where clicking a “CoinsPaid” option at Vegadream opened a GammaG pop-up with crypto deposit instructions; FinTelegram later described GammaG as a possible continuity rail in the CoinsPaid field. |
| CoinsPaid / CryptoProcessing orbit | Multi-jurisdictional | Branded crypto-processing/payment ecosystem referenced in FinTelegram investigations | In FinTelegram’s reporting, CoinsPaid-branded deposit flows led users into GammaG checkout/payment pages, suggesting operational proximity. |
Working takeaway: the strongest verified bridge at this stage is GammaG ↔ CoinsPaid on the payments-flow side and Sandra Kübarsepp ↔ GO DEFI CS s.r.o. on the GoDeFi side. The missing evidentiary step is a primary-source document proving that the same control persons or beneficial owners sit across both clusters.
Call To Whistleblowers And Insiders
If you are a current or former employee, contractor, compliance officer, card-program partner, exchange counterparty, merchant, casino operator, PSP, bank, EMI, or affected user with information about GoDeFi, GO DEFI CS s.r.o., Go Defi Corp., GammaG LLC, or their links to CoinsPaid, CryptoProcessing, Dream Finance, or the wider SoftSwiss orbit, contact FinTelegram confidentially via Whistle42. FinTelegram is particularly interested in:
- corporate records and shareholding documents,
- director and nominee arrangements,
- card-issuer and processor contracts,
- AML/KYC files,
- wallet and settlement architecture,
- correspondence about Georgia, Czech, or EU regulatory positioning,
- and any proof of common control or operational continuity.
The public deserves clarity on whether GoDeFi is simply a new fintech wrapper around a legitimate service model — or whether it forms part of a broader migration pattern in which high-risk crypto rails reappear under new names, new jurisdictions, and cleaner consumer branding.
