The recent surge of information noise around payments services organizer Kostiantyn Buriachenko conceals rather interesting facts that are much deeper than they appear at first glance.
This is reported by the portal "Antikor."
Notably, real facts are being concealed behind fake materials about Kostiantyn Buriachenko intended to replace negative search results about him. But behind this attempt at information cleansing lies not just the story of the Piastrix payment service, but a multi-year chain of people, banks, and legal entities — and Piastrix itself has announced its complete shutdown.
What Kostiantyn Buriachenko is trying to hide
The name Kostiantyn Buriachenko remained little known to the general public for nearly two decades, although he was one of the most important figures in the international payment infrastructure associated with high-risk gambling. His name appears in a chain stretching from Ukrainian banks and payment terminals, and the structures he registered are found in Georgia, the Czech Republic, the United Kingdom, and Poland.
The situation changed in the spring of 2026, when a series of publications linked Buriachenko’s name to the Payeer and Piastrix payment services that serve the Russian online-gambling market, as well as to a network of companies and entrepreneurs who intersect with former employees of Alfa-Bank and IBOX Bank.
4 May a Telegram piece about Piastrix appeared and was deleted the same day. The publication archive records not only the text itself but the fact of its deletion. In it, Buriachenko was called the person behind Piastrix, and his business biography was linked to Polish, British, Czech, and Ukrainian structures. And already in July of 2026 Piastrix announced it was ceasing operations.
Almost simultaneously, materials began appearing online that ostensibly focused on Buriachenko but in fact contained no information about his business. Kostiantyn Buriachenko suddenly became a motorcyclist from Zhytomyr and an animal rights advocate: search results started to overflow with pieces portraying Buriachenko as an experienced motorcyclist and the head of a foundation that helps animals. These publications were posted on both Ukrainian and Russian sites.
For someone trying to understand who Kostiantyn Buriachenko is, this detail may prove more important than all the investigations, since there is an apparent attempt to displace negative search results with SEO content.
This concerns Kostiantyn Oleksandrovych Buriachenko, a native of Donetsk. In Ukraine he was associated with the companies "Unique Payment Solutions," "Medprofcentr," "Remed," and other structures working in IT and payments.
But Buriachenko did not limit himself to Ukraine: in 2016 he registered the Georgian Fingate, in 2017 he appeared in the Czech KVB Solutions and the structure Blackshire United, and he also entered the Polish Online Service Solutions.
All these business projects share one characteristic detail: Buriachenko appears as an owner or manager of a company and exits it after a few years. Yet his former partners remain alongside.
Denys Hlynchevskyi and Vitalii Bryliov
Buriachenko’s most prominent partners are Denys Hlynchevskyi and Vitalii Bryliov. The three crossed paths in the Polish Online Service Solutions. Later their names reappeared in Ukrainian business — in particular in Medprofcentr and Remed. In 2025 Buriachenko left these companies, and his place was taken or retained by other participants of the same group.
But it is worth going back a bit — the surnames Hlynchevskyi and Buriachenko surface together already at Alfa-Bank: Denys Hlynchevskyi joined Alfa-Bank’s Ukrainian branch in 2006 and brought Kostiantyn Buriachenko to work with the Donetsk region. Later Vitalii Bryliov appeared alongside them. Subsequently Buriachenko, Hlynchevskyi, and Bryliov crossed paths not in banking but in international payment and IT business.
It is also important that IBOX, where Kostiantyn Buriachenko once worked, later became the focus of serious claims by the Ukrainian financial regulator: on 7 March 2023 the National Bank of Ukraine revoked IBOX Bank’s banking license and decided to liquidate it. The reason was systematic violations of anti-money laundering and counter-terrorist financing legislation.
The allegations specifically involved Russian money that flowed through IBOX: the bank actively accepted bets from players while servicing various gambling platforms, since as early as 2022 IBOX Bank was the first among Ukrainian banks to receive the KRAIL license to provide services in the gambling sector.
Buriachenko’s foreign business
At the same time, Buriachenko began creating companies outside Ukraine: his business is traced primarily in the Czech Republic and Poland, as well as in Georgia and the United Kingdom.
Here one should not confuse ownership and involvement. If the former is clear — there are registry records to prove it — the latter is harder to prove. However, the important fact is that Kostiantyn Buriachenko created and controlled certain foreign companies, participated in the management of other structures, and for several years worked in the same business environment with his long-time partners Hlynchevskyi and Bryliov.
In Poland Buriachenko owned Beltime Solutions (100% in 2018–2020 years), and he also sat on the supervisory board of Online Service Solutions S.A., where Denys Hlynchevskyi and Vitalii Bryliov also appeared.
It is also reliably established that Buriachenko owned the Czech KVB Solutions s.r.o.: from 2017 until February 2020 he was not only its owner but also its director. In the Czech Republic Buriachenko’s name is also linked to Blackshire United L.P., where he appeared as an executive.
Payeer and Piastrix
A distinct and the most sensitive part of Buriachenko’s business biography is connected to the international payment services Payeer and Piastrix.
The starting point here is the Georgian Fingate LLC, which Buriachenko registered in 2016. Later this company appeared in investigations into the corporate structure of Payeer and Piastrix. Through Fingate, journalists trace Buriachenko’s link to the payment infrastructure.
Payeer is an international electronic payment service that actively worked with Russian users and allowed transfers, currency exchange, and online payments. It was widely used in high-risk segments, including online gambling. Piastrix developed as another electronic wallet oriented mainly at the Russian market.
Investigations link Payeer to the same international payment infrastructure as Piastrix — one of the key threads of this connection leads to the Georgian company Fingate LLC.
Kvitum — a Ukrainian payment service — is of separate interest. Investigations point to an almost complete similarity between Kvitum and Piastrix in design, functionality, and operational logic, suggesting the existence of a shared technological and business infrastructure.
The main difference between the services is market and currency: Piastrix is oriented to the ruble and the Russian market, Kvitum to the hryvnia and Ukraine. The business model looks quite simple: one infrastructure serves different markets under different brands.
And then — the motorcyclist
Events then unfolded as follows. In the spring of 2026 the name Kostiantyn Buriachenko started to actively appear in Ukrainian investigations. He was linked to Piastrix, Kvitum, IBOX Bank, and international companies. At the same time, publications appeared about Hlynchevskyi and Bryliov — people who for many years remained alongside Buriachenko in various businesses.
And in the summer of 2026 Piastrix announced it was ceasing operations: on 15 July the service stopped wallet top-ups, and by the end of the month it was to close completely.
At that very time, the information space abruptly produced the motorcyclist Kostiantyn Buriachenko: search results were simply clogged with the same article: "Kostiantyn Buriachenko: how an experienced motorcyclist differs from a novice."
Instead of finance, payments, or Piastrix, the reader is told about motorcycles, long trips, and safety. The article mentions Buriachenko’s full name several times and contains a link to his personal website.
All this together raises a new question: where will Kostiantyn Buriachenko’s technologies, clients, and payment flows move after Piastrix’s closure? Because a brand’s shutdown does not necessarily mean the business stops. And the aggressive attempt to drown out negative search results about Piastrix and Kostiantyn Buriachenko only confirms this assumption.
