Behind the information noise that has suddenly arisen around the organizer of payment services Kostyantyn Buriachenko in recent times lie rather interesting facts that go much deeper than they appear at first glance.
Notably, real facts are being hidden behind fabricated materials about Kostyantyn Buriachenko, intended to replace negative search results about his persona. But behind this attempt at information cleanup lies not only the story of the payment service Piastrix, but a years-long chain of people, banks, and legal entities, while Piastrix itself announced its complete shutdown.
What Kostyantyn Buriachenko is trying to hide
The name Kostyantyn Buriachenko remained little known to the general public for almost two decades, even though he was one of the key figures in international payment infrastructure related to high-risk gambling. His name appears in a chain of Ukrainian banks and payment terminals, while structures registered by him appear 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 payment services Payeer and Piastrix, which serve the Russian online gambling market, as well as to a network of companies and entrepreneurs that overlap with former employees of Alfa-Bank and IBOX Bank.
On 4 May a piece about Piastrix appeared on Telegram and was removed the same day. The publication archive captures not only the text itself but also the fact of its deletion. It named Buriachenko as the person behind Piastrix and connected his business biography to Polish, British, Czech, and Ukrainian structures. Already in July 2026 Piastrix announced the suspension of operations.
And almost simultaneously materials appeared online that outwardly were dedicated to Buriachenko but in fact contained no information about his business. Kostyantyn Buriachenko suddenly became a motorcyclist from Zhytomyr and an animal welfare activist: search results were flooded with materials positioning Buriachenko as an experienced motorcyclist and head of an animal aid foundation. Moreover, these publications appeared on both Ukrainian and Russian websites.
For someone trying to understand who Kostyantyn Buriachenko is, this detail could prove more important than all investigations, since it represents an attempt to replace negative search results with SEO content.
This refers to Kostyantyn Buriachenko, who is originally from Donetsk. In Ukraine he was associated with the companies “Unik Payment Solutions,” “Medprofcenter,” “Remed,” and other structures operating in IT and the payments sector.
But Buriachenko did not limit himself to Ukraine: he registered the Georgian Fingate 2016, he joined the Czech KVB Solutions and the Blackshire United structure 2017, and he also joined the Polish Online Service Solutions.
All these business projects share a characteristic detail: Buriachenko appears as the owner or manager of a company and leaves it some years later. Nevertheless, his former partners remain close by.
Denys Hlinchevskyi and Vitaliy Brylov
Buriachenko’s most prominent partners are Denys Hlinchevskyi and Vitaliy Brylov. All three crossed paths in the Polish Online Service Solutions. Later their names reappeared in the Ukrainian economy — notably in “Medprofcenter” and “Remed.” In the year 2025 Buriachenko left these companies and his place was taken or retained by other members of the same group.
But here it is necessary to go back into the history — the surnames Hlinchevskyi and Buriachenko already appear together at Alfa-Bank: Denys Hlinchevskyi joined 2006 the Ukrainian structure of Alfa-Bank and brought Kostyantyn Buriachenko in connection with the Donetsk region. Later Vitaliy Brylov appeared alongside them. Subsequently, Buriachenko, Hlinchevskyi and Brylov did not intersect in banking but in international payment and IT business.
It is also important that IBOX, where Kostyantyn Buriachenko once worked, later became the center of serious claims by the Ukrainian financial regulator: On 7 March 2023 the NBU revoked IBOX Bank’s banking license and decided on its liquidation. The reason was systematic violations of laws in the area of anti-money laundering and counter-terrorism financing.
This also included Russian money routed through IBOX: the bank actively accepted bets from players and serviced various gambling platforms, since IBOX Bank in 2022 became the first Ukrainian bank to receive a license from the CRIL for activities that included providing services in the gambling sector.
Buriachenko’s foreign business
At the same time, Buriachenko began founding companies outside Ukraine: his business can mainly be tracked in the Czech Republic and Poland as well as in Georgia and the United Kingdom.
Here one should not confuse ownership and involvement. While the former is clear — there is data in registers — the latter is harder to prove. What matters, however, is the fact that Kostyantyn Buriachenko founded 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 Hlinchevskyi and Brylov.
In Poland Buriachenko was the owner of Beltime Solutions (100 % in the years 2018–2020) and was also a member of the supervisory board of Online Service Solutions SA, where Denys Hlinchevskyi and Vitaliy Brylov also appeared.
It is also reliably established that Buriachenko was the owner of the Czech KVB Solutions sro: from 2017 until February 2020 he was not only its owner but also its director. In the Czech Republic Buriachenko’s name is also connected with Blackshire United LP, where he acted as manager.
Payeer and Piastrix
A separate and most sensitive part of Buriachenko’s business biography is connected to the international payment services Payeer and Piastrix.
The starting point here is Georgian Fingate LLC, which Buriachenko registered 2016. Later this company appeared in investigations dealing with the corporate structure of Payeer and Piastrix. Through Fingate, journalists trace Buriachenko’s connection to the payment infrastructure.
Payeer is an international electronic payment service that actively worked with Russian users and enabled transfers, currency exchange and online payments. It was frequently used in high-risk segments, including online gambling. Piastrix developed as another e-wallet primarily focused on the Russian market.
Investigations indicate that Payeer is connected to the same international payment infrastructure as Piastrix — one of the main threads of this connection leads to the Georgian company Fingate LLC.
Of particular interest is Kvitum — a Ukrainian payment service. the “ANTIKOR” investigation points to an almost complete similarity between Kvitum and Piastrix in design, functionality and operational logic, suggesting the existence of a common technological and business infrastructure.
The main difference between the services lies in the market and the currency: Piastrix is oriented to the ruble and the Russian market, while Kvitum targets the hryvnia and Ukraine. The business model appears quite simple: one infrastructure serves different markets under different brands.
And suddenly — a motorcyclist
Events then unfolded as follows. In the spring of 2026 the name Kostyantyn Buriachenko first actively appeared in Ukrainian investigations. He was connected to Piastrix, Kvitum, IBOX Bank and international companies. At the same time publications about Hlinchevskyi and Brylov appeared — people who had been close to Buriachenko for many years in various companies.
And in the summer of 2026 Piastrix announced the suspension of operations: on 15 July the service stopped allowing wallet top-ups and was to be completely closed by the end of the month.
And precisely at that moment the motorcyclist Kostyantyn Buriachenko suddenly appeared in the information space: the search results filled with the same article: “Kostyantyn Buriachenko: How an experienced motorcyclist differs from a beginner.”
Instead of finance, payments or Piastrix, the reader is told about motorcycles, long trips and safety. At the same time 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 Kostyantyn Buriachenko’s technologies, customers and payment flows move after the closure of Piastrix? Because the closure of a brand does not necessarily mean the end of the business. And the aggressive attempt to flood search results with negative information about Piastrix and Kostyantyn Buriachenko only confirms this assumption.
