The article seeks to further our understanding of the process of organizing nascent social ventures. It builds upon current research on the political and collaborative nature of the social entrepreneurial process, and takes an ANT-inspired processual approach to follow the organizational practices carried by a nascent social venture in its efforts to mobilize stakeholders, bring about collaboration and ultimately secure resources. It draws upon empirical material generated during the first year of a social venture I founded and continue to chair. Findings highlight the adaptive and fluid nature of the organizational practices involved in nascent organizations and indicate that the capacity to continuously adjust the qualities of the eventual venture to the stakes of potential partners is instrumental to start up the venture. The article suggests the notion of tinkering to underscore the fluidity, the ongoing and piecemeal everyday work of such organizing processes. Further, findings highlight the extent to which social ventures, as well as the engaged scholar, are caught in the networks that contribute to reproduce the social problem they aim to change.
