A report from IEDC-Bled School of Management claims that Slovenia and Serbia have the most “hidden champions” in Southeast Europe, with these being successful and innovative but not well-known small and medium-sized companies, among the best in the world in terms of market share in their respective niche or among the top two in a region.
The European Bank for Reconstruction and Development (EBRD) co-financed the report and said that it was “based on field research in 2018 and 2019 in 22 countries in the central, eastern and south-eastern Europe (CESEE) region”. The country with the greatest number of “hidden champions” was Poland (with 11), followed by Belarus (10), Serbia (10) and Slovenia (10).
