From November 29 through December 2 2019 Šymon Kliman, founder and an expert of the Cvernovka Foundation / New Cvernovka, took part in a foreign business trip to the town of Niš at the KreNi conference in order to lecture on the transformation of abandoned premises, meetings with coworking representatives from Niš and mentoring with KreNI conference groups. The lecture was very successful for the conference participants, the positive example was very motivating for young people and the lecture was followed by a very intensive discussion on financing, project management, confidence building, etc.
