Abstract
The research analyzed the effects of knowledge sources (internal and external) on innovation culture and frugal innovation in a sample of 85 social startups. Hypothesis testing was carried out through partial least squares structural equation modeling (PLS-SEM) in the SmartPLS 3 software. The results suggest that internal knowledge sources promote the culture of innovation directly and frugal innovation indirectly, while External knowledge sources have a direct impact on frugal innovation. As an additional analysis, the study reveals that the combination of knowledge sources (internal and external) is relevant to fostering a culture of innovation.
