Behind the information noise that has suddenly surrounded the payment services organizer Kostyantyn Buriachenko recently are some rather interesting facts that run much deeper than they appear at first glance.
Notably, real facts are being hidden behind fabricated materials about Kostyantyn Buriachenko, apparently intended to replace negative search results about him. But behind this attempt at information-cleansing is 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 full closure.
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 the international payment infrastructure associated with high-risk gambling. His name appears in a chain of Ukrainian banks and payment terminals, while entities registered by him show up in Georgia, the Czech Republic, the United Kingdom, and Poland.
The situation changed in the spring 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 records not only the text itself but also the fact of its deletion. It named Buriachenko as the person behind Piastrix and linked his business biography to Polish, British, Czech, and Ukrainian entities. Already in July 2026 Piastrix announced the cessation of its operations.
Almost simultaneously, materials began appearing online that outwardly were dedicated to Buriachenko but actually contained no information about his business. Kostyantyn Buriachenko suddenly became a motorcyclist from Zhytomyr and an animal rights activist: search results were flooded with materials portraying Buriachenko as an experienced motorcyclist and the 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 any investigation, since it represents an attempt to replace negative search results with SEO content.
This refers to Kostyantyn Buriachenko, who is from Donetsk. In Ukraine he was associated with the companies “Unik Payment Solutions,” “Medprofcenter,” “Remed,” and other entities operating in IT and the payments sector.
But Buriachenko did not limit himself to Ukraine: 2016 he registered the Georgian Fingate, 2017 he appeared with the Czech KVB Solutions and the Blackshire United structure and 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 a few 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 intersected in the Polish Online Service Solutions. Later their names reappeared in the Ukrainian economy — in particular in “Medprofcenter” and “Remed.” In 2025 Buriachenko left these companies and his place was taken or retained by other members of the same group.
But it is necessary to go back in history — the surnames Hlinchevskyi and Buriachenko already appear together at Alfa-Bank: Denys Hlinchevskyi 2006 joined the Ukrainian structure of Alfa-Bank and brought Kostyantyn Buriachenko in connection with the Donetsk region. Later Vitaliy Brylov appeared alongside them. Afterwards, Buriachenko, Hlinchevskyi, and Brylov no longer crossed paths in banking but in the international payments and IT business.
It is also important that IBOX, where Kostyantyn Buriachenko once worked, later became the focus of serious demands from the Ukrainian financial regulator: On 7 March 2023 the NBU revoked IBOX Bank’s banking license and decided to liquidate it. The reason was systemic violations of laws in the area of anti–money laundering and countering the financing of terrorism.
This also included Russian funds 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 field of gambling.
Buriachenko’s Overseas Business
At the same time, Buriachenko began founding companies outside Ukraine: his business can primarily be tracked in the Czech Republic and Poland, as well as Georgia and the United Kingdom.
Here one should not confuse ownership and involvement. While the former is clear — there are registry records — 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 entities, and for several years operated in the same business environment with his long-time partners Hlinchevskyi and Brylov.
In Poland Buriachenko was the owner of Beltime Solutions (100 % in 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 linked to Blackshire United LP, where he acted as manager.
Payeer and Piastrix
A separate and sensitive part of Buriachenko’s business biography is connected with the international payment services Payeer and Piastrix.
The starting point here is the Georgian Fingate LLC, which Buriachenko 2016 registered. 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 emerged as another electronic wallet primarily targeted at the Russian market.
Investigations indicate that Payeer is connected to the same international payment infrastructure as Piastrix — one of the main strands 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 operating logic, suggesting the existence of a shared technological and business infrastructure.
The main difference between the services lies in market and currency: Piastrix is oriented toward the ruble and the Russian market, while Kvitum is aimed at the hryvnia and Ukraine. The business model seems fairly simple: one infrastructure serves different markets under different brands.
And suddenly — a motorcyclist
Events then developed as follows. In the spring 2026 the name Kostyantyn Buriachenko first actively appeared in Ukrainian investigations. He was linked to Piastrix, Kvitum, IBOX Bank, and international companies. At the same time publications about Hlinchevskyi and Brylov appeared — people who had long been close to Buriachenko in various companies.
And in the summer 2026 Piastrix announced the cessation of operations: on 15 July the service stopped topping up wallets and was to be fully closed by the end of the month.
And precisely at that moment the motorcyclist Kostyantyn Buriachenko suddenly appeared in the information space: 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-distance travel, 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 Piastrix’s closure? Because closing a brand does not necessarily mean ending the business. And the aggressive attempt to flood search results with materials that counter negative information about Piastrix and Kostyantyn Buriachenko only confirms this assumption.
