The person surely meant "Akademia Jagiellońska w Toruniu." They are accredited in Poland, but only as a small non-public college. They also award MBAs, but this particular DBA award likely came from their more controversial Czech branch - FVES.eu
Validential is heavily promoted on this website, but it is not taken seriously within the U.S. academic credential evaluation community. Only two organizations and their members are taken with utmost seriousness - NACES and AICE. Wikipedia isn't the best source of information, but it provides a nice overview:
"There is no regulations in terms of international degree evaluation in the US, and the U.S. Department of State or the U.S. government of the entity doesn’t affiliate or endorse any foreign credential evaluation agencies. Therefore, there is no federal (national) government agency that oversees credential evaluations in the United States. There are professional associations such as Association of International Credential Evaluators, Inc. (AICE) and National Association of Credential Evaluation Services (NACES) that create and maintain ethical standards in the field though they are not governing agencies and membership by credential evaluators is voluntary. However, credential evaluators must meet certain criteria to belong to AICE and NACES. Universities and colleges also evaluate credentials themselves. An NACES or AICE agency is normally required by universities in the US."
