We empirically explore Incubator-BUS (I-BUS), a student organization within a private Brazilian university, which sought to incubate cooperatives for vulnerable groups. Although initially successful in balancing its missions, I-BUS then failed. We show how scaling-up can complicate the balancing of different missions within the same organization. We propose that, to balance their missions, social enterprises¡ªespecially recently formed and democratically managed enterprises¡ªneed not only ¡°spaces of negotiation,¡± as suggested in the literature, but also ¡°herding spaces¡± that connect an organization to its institutional context. We indicate why herding spaces are critical, but then show how scaling-up can result in organizational ¡°compartmentalization¡± that undermines them %K incubator %K mission drift %K scaling %K social enterprise %K spaces %U https://journals.sagepub.com/doi/full/10.1177/0007650318758329
