The aim of this study is to analyze this source of financing, assess its development globally and in Poland. In the preparation of the article,. a critical analysis of foreign and Polish literature was carried out, and descriptive and comparative research methods applied. The research task undertaken in the study was to analyze the crowdfunding market globally and in Poland.
