Our history

Our vision

The story begins in the 2013 when LY International Sp z o.o. was established in Kielce (Poland) – that was our first name. One year later, in 2014, we moved our headquarter department to Wrocław (Poland) and changed corporate name to YOON Group Sp z o.o. which existing until now. After that we decided that we have to extract separate department which will be responsible directly for the ENC Business and in case of that in 2015 we established YOON Group Sp z o.o. S.k. This year we also relocated our head office to another office in Wrocław (Poland). In 2018 we established new branch office, this time in Budapest (Hungary).

Because we are still developing and our team is growing very fast in 2019 we had to change our office again for the bigger one. Nowadays we are located in Business Point Bielany (Bielany Wrocławskie) and we are planning to expand our ranges for another areas.

You don't think your way to creative work. You work your way to creative thinking.
