Macro-economic policies such as public financing seek to push the development and introduction of innovations; however, entrepreneurs also need support in their ‘day-to-day’ activities to improve their capability to launch innovations. As this micro-level perspective is rarely studied, we analyze both the micro and macro levels by examining the effects of the entrepreneurs’ individual intention to innovate and public financing. Additionally, we include the meso level, representing entrepreneurs’ network. Entrepreneurs are embedded in social spheres in which they capture resources and identify opportunities. But not all entrepreneurs are equally well supported, and some tend to be completely isolated. We thus focus on multilevel factors explaining new product or service launching in new ventures. Drawing on data of 48,251 French new ventures, we reveal that innovation intention and public financing positively impact new ventures’ product and service innovation launching, while entrepreneurs’ isolation has a negative effect. We also highlight two interaction effects that enhance the multilevel effects of innovation antecedents.
