Our longitudinal study of eleven founder-run firms allowed us to induct a hierarchical typology of resourceful behaviors that is useful both in making sense of scattered prior work on entrepreneurial resourcefulness – for example bricolage, improvisation, bootstrapping and thrift – and for guiding future work. Based on our preliminary findings, we propose that by engaging in different sorts of resourceful behaviors founders enact their resource environments in distinctly different ways. Our study provides a foundation for an integrated theory that helps to explain sources and variations in entrepreneurial resourcefulness.
