Abstract: Product innovativeness is central to entrepreneurship, but extant measures are problematic for entrepreneurship research because they tend to be firm‐level and/or subjective and lack validity and reliability for new and small firms. We develop a new measure of product innovativeness that is direct, objective, contemporary, and cardinal that provides entrepreneurship researchers with a reliable measure of innovativeness at the product level that will facilitate consistent measurement of this construct in cross‐sectional and longitudinal studies of product innovation. The new measure is developed as a formative measurement model using composite indicators that are objectively identified by observation of the new product and can be used to compare rival products or a particular firm's product innovations over time.
