The recent health service delivery achievements in Bangladesh have been attributed, in part, to partnerships between the government and non-state actors and the early and rapid adoption of innovations. Through the analysis of two case studies, this article examines the factors contributing to successful partnerships for health market innovations in Bangladesh and the extent to which these innovations can contribute to market systems changes that benefit the poor. The first case examines an innovation which aims to address maternal and child health issues by creating access to information on prenatal and post-natal care through mobile phones. The other case illustrates how Bangladesh's leading NGO partnered with one of the largest pharmaceutical companies in Bangladesh to develop a model for rural distribution of a micronutrient food supplement, ‘sprinkles’, to tackle the problem of micronutrient deficiency in young children.
