This paper examines the effects of innovativeness, creative climate and learning on high growth. We study how fast-growing SMEs, known as gazelles, differ from other SMEs. A survey of 345 Norwegian gazelles and 135 non-gazelles supports the idea that innovativeness is an important factor in whether a company becomes a gazelle. Creative climate, learning and innovativeness were conceptualized and analyzed as first-order constructs using confirmatory factor analysis, OLS and Probit regression. Learning and creative climate were found to have a positive impact on growth through innovativeness. Based on the data, it seems that younger companies are more likely to be innovative and grow quickly.
