The effects of companies on society and the practices of Corporate Social Responsibility have been the source of interest for many research studies. Questions concerning the traditional model resulted in Porter and Kramer developing the concept of Creating Shared Value, an approach where companies consider the value of society and the environment in their business models, creating value for all stakeholders. We take the issue of shared value creation in an entrepreneurial ecosystem to determine how clustered companies understand and create shared value, identifying its antecedents and consequences. Using a single case study, we were able to identify that the entrepreneurial ecosystem becomes a favourable scenario for creating shared value, because participants benefit from resources and skills that allow them to grow their businesses, boost competitiveness and innovation and contribute to the economic, social, and environmental growth of their stakeholders.
