This study examines the correlation between the Entrepreneurial Behavioral Characteristics (CCEs) proposed by David McClelland and the changes in the Business Model Canvas (BMC). The objective was to understand how the CCEs present in three different entrepreneurs impacted the modification of their respective companies' BMCs to overcome the difficulties that arose during the COVID-19 pandemic. For this purpose, we analyzed the changes in the BMC of three companies in the children's party sector in Curitiba, PR, in the pre, during, and post-pandemic contexts. Additionally, the CCEs of each entrepreneur were identified through questionnaires. Finally, the changes in the business model components were correlated with the characteristics of each entrepreneur. The analysis revealed that the connection between these tools (BMC and CCEs) did not present a consistent pattern for all cases. However, it was possible to correlate the characteristics and changes in the business model by understanding the context, motivations, and strategies used by each entrepreneur.
