Crowdfunding is one of the alternative financing methods that businesses use to secure the resources they need in addition to existing ones (traditional ones) or even instead. The development of technology has greatly helped the development of crowdfunding as a way of financing, and it is important to determine how successful the funding is through this and what are the determinants on which to measure performance. Also, it is necessary to identify differences in the use of crowdfunding as a way of financing in Croatia in relation to world practices in order to promote it. The aim of the paper is to define the success factors of Crowdfunding campaigns and to explore and compare examples of global and Croatian campaigns. The paper will first of all theoretically determine the notion of crowdfunding and indicators that indicate the (in) success of campaigns. Also, examples of successful campaigns will be given, with particular emphasis on campaigns implemented in the Republic of Croatia. The paper shows that crowdfunding can raise significant amounts of funds, but almost all of the most successful campaigns have been conducted on Kickstarter and have been conducted by U.S. companies. It is evident that each crowdfunding campaign is very specific, for example a significant number of campaigns have a characteristic of product sales, but the occurrence of a repeat campaign with the emergence of a new version of a product for which a successful crowdfunding campaign has been carried out is increasingly common. Also, a very specific crowdfunding campaign is related to sales (sales because the campaign was launched over 3 years and it is noticeable that the campaign actually sells olive oil and accommodation service on the island of Hvar), but also at prices higher than the prices that would be achieved in the local market. When it comes to Croatian crowdfunding campaigns, it is evident that there has been a significant increase in the number of campaigns and the amount of funds raised, while the current record brewery Medvedgrad has raised EUR 1 million. When it comes to analyzing the factors that affect a campaign's success, it can be concluded that these factors are very numerous, and it is necessary to pay attention to each of them when conducting the campaign.
