Entrepreneurial ventures need frequently to adapt. Yet their adaptive capacity is often limited by the legacies of imprinted founding characteristics. The question then arises whether it is possible to explain and manage the imprinting process so that the capacity to adapt is enhanced, rather than diminished. I address this question by developing a model of the microfoundations of imprinting based in collective memory. I argue that entrepreneurial founding teams naturally develop transactive autobiographical memory systems. By partially managing the design and imprinting of these memory systems, I argue that founders may improve their venture's long‐term capacity to adapt.
