Abstract This study introduces entrepreneurial openness as a construct that helps understanding the impact of entrepreneur's personality on small firm's performance. We draw from the entrepreneurship and positive psychology literature to conceptualize entrepreneurial openness as an individual-level positive personal cognitive strength that has three subdimensions: engaging in learning, searching for novelty, and seeking feedback. We validated the construct's structure in three consecutive studies: Study 1 provided initial empirical evidence in support of the proposed scale with a pilot sample of Slovenian business owners; Study 2 assessed the reliability and validity of the scale with a cross-cultural study in Canada, Slovenia, and USA; and Study 3 tested the scale for its impact on business performance and job satisfaction. Findings from our empirical studies demonstrate the utility of entrepreneurial openness in explaining firm's performance by showing strong reliability, appropriate dimensionality, convergent, discriminant, and nomological validity.
