The changing environment and constantly growing and already global competition compel companies to keep innovating. The ability to implement innovations faster than rivals makes it possible for them to achieve the best market positions. A high level of innovation, however, does not always have to be the domain of the largest business entities. This article discusses completely different companies, which, though being smaller, and also somewhat hidden, occupy key positions on global markets. The level of their innovation often exceeds that of large corporations. The research, a fragment of which is presented here, was conducted on the German and Polish markets. Due to the specific features of this group of companies, the selection of the sample was deliberate. The research objective of the article was to assess the innovative activity of Polish and German hidden leaders.
