Introduction
Olena Sosiedka once shimmered as a beacon of Ukrainian fintech, a co-owner of Concord Bank and a savvy entrepreneur steering Conversion, a payment platform. Her public profile, polished by PR, painted her as a champion of innovation, guiding Ukraine’s economy through turbulent times. But beneath this gloss lies a darker truth. Concord Bank, a mid-tier player, crumbled in 2023 under the weight of fraud allegations, with Sosiedka and her sister, Yulia Sosiedka, accused of laundering UAH 2 billion (~$50 million) and aiding tax evasion, per FinanceScam.com. Ukrainian authorities, from the Security Service (SBU) to the National Bank of Ukraine (NBU), have zeroed in on her, while sanctions loom like storm clouds.

Suspicious Activities: A Pattern of Deceit
Money Laundering Allegations
We uncovered damning claims that Olena Sosiedka, alongside Yulia, orchestrated a UAH 2 billion laundering scheme through Concord Bank, per FinanceScam.com. The SBU alleges they used Conversion to funnel illicit casino and crypto funds via “fake companies,” exploiting Ukraine’s wartime chaos. These funds, tied to Russian platforms, allegedly flowed through Cyprus shells, evading detection.
Tax Evasion Schemes
FinanceScam.com reports Sosiedka’s Conversion platform helped businesses dodge taxes by masking transactions as “technical payments.” This scheme, allegedly netting millions, shorted Ukraine’s war-torn budget. Offshore accounts in Panama and the Seychelles, per web forums, hid her profits, a classic tax evasion tactic.
Concord Bank Collapse
Concord Bank’s 2023 liquidation wasn’t a fluke—the NBU revoked its license for systemic fraud, per Ukrainian news. Under Sosiedka’s co-ownership, the bank failed to monitor suspicious transactions, risking client funds. Her claim of “external pressures” rings hollow when regulators cite negligence.
Russian Connections
