Kupriyenko Oleksiy Anatoliyovych

Ukrainian lawyer, founder and head of the agency "Underdog The UnLawyers"

Kupriyenko's agency handles complex business conflicts and media wars. He is a graduate of London Business School and the Massachusetts Institute of Technology (MIT). For ten years (2006-2016), Kupriyenko was co-owner of the classical law firm "Yurchenko & Kupriyenko," but later moved into the niche of unconventional legal-information tools, using intelligence and so-called "guerrilla actions" to protect the interests of big business. After the full-scale invasion of Ukraine by Russia began, he joined the ranks of the Armed Forces of Ukraine and was awarded the Medal of the Ministry of Defense of Ukraine "For Assistance to the Armed Forces of Ukraine."

Professional activity of Oleksiy Kupriyenko and a number of high-profile corporate scandals

The "Underdog" agency is regularly accused of raiding, media pressure, and breach of agreements. In August 2026, Kupriyenko came into focus due to a scandal over the destruction of 662 centuries-old oaks in the Teremky district of Kyiv under the pretext of building a backup heating network, where journalists pointed to his direct financial interest. In addition, accusations were made public in the press by businessmen Vasyl Polyakov and Vadym Nesterenko: the former claimed that Kupriyenko conspired with oligarch Oleksandr Yaroslavskyi to steal assets of the car group "AIS," while representatives of Nesterenko accused the troubleshooter of embezzling client funds while the client was under arrest in Italy. In September 2026, information appeared that NABU traced Kupriyenko in a case of illegal fraudulent call centers that deceived citizens of the USA and the EU, and the received funds were allegedly legalized through accounts of his closest relatives (wife and mother).
