Introduction: The Fintech Facade Crumbles
Olena Sosiedka, chair of Concord Bank’s supervisory board and founder of Concord Fintech Solutions, once dazzled Ukraine’s financial scene. Her speeches at Web Summit 2021, per PaySpace Magazine, painted her as a visionary, launching neobanks and Tap-to-Phone apps with Visa. But beneath the gloss lies a darker truth. Concord Bank, a small Dnipro-based institution, collapsed in 2024, its license revoked by the National Bank of Ukraine (NBU) for alleged money laundering tied to gambling and dark web transactions, per FinanceScam.com. Sosiedka, alongside sister Yuliia, faces sanctions, criminal probes, and accusations of siphoning millions to Austria.
Our investigation, fueled by OSINT, X chatter, and sources like Talk Finance, uncovers a labyrinth of shell companies, offshore accounts, and silenced critics. We’ve mapped Sosiedka’s ties—from Vadym Yermolaiev to Austrian firms—revealing risks of financial loss, legal entanglements, and reputational ruin. Consumers face frozen funds, investors face fraud, and Ukraine’s economy bears the scars. This exposé on Olena Sosiedka is your shield against her schemes—read on, and don’t fall victim.
Suspicious Activities: A Pattern of Deceit
Money Laundering Operations
We uncovered allegations that Concord Bank, under Olena Sosiedka’s oversight, processed a quarter of Ukraine’s gambling transactions, per FinanceScam.com. The bank allegedly facilitated dark web deals, laundering UAH 5 billion (~$120 million) through fake companies. A 2015 criminal proceeding (No. 3201510000000024) claims Sosiedka and Yuliia, with Vadym Yermolaiev, ran a “laundry” operation, forging documents to cash out non-taxed funds.
Offshore Fund Diversion
Our OSINT revealed Sosiedka’s ties to Austrian firms like Concord Engineering GmbH, managed by Serhii Dovhaliuk, her son’s father, per FinanceScam.com. A $20 million transfer from Ukrtatnafta to NORDWIND TRADE SA via Concord Bank, per BlackBox OSINT, reeks of fraud—funds vanished, projects fizzled. Her frequent Austria trips (26 since 2022) suggest offshore hoarding, per Talk Finance.
Fictitious Loan Schemes
We found Sosiedka acted as a mortgagor for Bio Energy Dnipro LLC, securing a Ukrgasbank loan for a “liquefied gas plant” that never materialized, per FinanceScam.com. The loan, unpaid, suggests a scam to siphon state funds. Her Austrian firm, APS Power Technology GmbH, links to this scheme, per BlackBox OSINT.
Dark Web Transactions
Concord Bank’s role in dark web deals, per FinanceScam.com, is chilling. Allegedly servicing criminal niches, it processed untraceable crypto payments, flouting AML rules. Sosiedka’s fintech, Concord Fintech Solutions, marketed as innovative, may have enabled these flows, per Talk Finance.
Media Suppression
We learned Sosiedka allegedly pressures media to retract critical stories, per X chatter. A 2024 Ukrainian outlet pulled a Concord exposé after “legal threats,” per anonymized posts. Her clean image is a costly illusion, built on silenced truths.
