This research aims to understand the contribution of transformational leadership to employee Portuguese startups' creativity. An empirical study was conducted using a quantitative methodological approach, with the application of an online questionnaire sent to Portuguese startups. 102 employee responses were validated. The results obtained showed the existence of a positive and significant relationship between transformational leadership and creativity in Portuguese startups. Therefore, we conclude that it is recommended that startups use this leadership style so that, as a consequence, they can obtain higher results in terms of organisational creativity.
