Untapped markets are often deemed institutional voids, terra incognita ripe with economic possibility. The conversion of institutional voids into viable markets has become the ambition of many corporations today, which view marginal and under-served areas such as urban slums as opportunities to achieve the dual aims of market growth and poverty reduction, particularly through 'bottom of the pyramid' (BoP) programmes. This article examines how firms manage institutional voids and the consequences of these approaches for workers through a case study of a BoP 'route to market' programme designed by a global food manufacturer in Kibera, Africa's largest slum, located in Nairobi. Instead of engaging with Kibera by upgrading informal markets or generating formal employment, the corporation focused on harnessing existing informal systems through composite arrangements of NGOs, social networks and informal enterprises, a strategy the authors term 'remote (dis)engagement'. The article describes the logics and outcome of this strategy of formal engagement with informal markets, concluding that the BoP business model depends on 'gig practices' of flexibility, irregular work and insecurity to realize the much-heralded 'fortune at the bottom of the pyramid'.The authors would like to acknowledge the editors and reviewers for their valuable input; in particular, we would like to thank Dr Kate Meagher for her guidance and support.
