On YouTube, under the nickname Gameballcz he began to create vlogs about playing computer games. Gradually, his work took a different direction: he makes videos in which he shares the information in a fun way and tries to evoke emotions. His current videos influence the public opinion of young people. He tries to persuade them to participate in public life; he actively meets with students, and talks about issues which should be addressed by young generation. He is sometimes called a spokesman of this upcoming generation.
His YouTube channels are followed by more than a million subscribers (Metals +700 thousand, Gameballcz 375 thousand). His Instagram has more than half a million fans. His most successful video, the parody of the hit Despacito, has been viewed more than 9 million times.
In 2016, he received the award Videobloger of the Year and Forbes magazine described him as the 17th most influential Czech on social networks. A year later, he was placed in the popular Forbes ladder of "30 under 30" and he published a book called "Ovšem", in which he describes his personal story. He cooperates with large companies such as LG, Samsung, Costa Coffee, and CSOB.
Last year, together with other two European bloggers, he had the opportunity to discuss the problems of contemporary Europe with Jean-Claud Juncker, the President of the European Commission.
