Lockme is the largest website for browsing, booking and rating escape rooms from all over Poland - but not only. It has begun its expansion and is already available in Germany, Austria, Switzerland or USA. The website works as a marketplace which in Poland concentrates over 95% of the market (and is constantly growing). It was created in December 2014 on the basis of a special algorithm by two escape rooms enthusiasts - Jakub Caban and Bartosz Idzikowski - then involved in creating websites. Here we publish content about polish and global market, our website or current escape rooms industry trends.
