This thesis presents the multinational hybrid organization (MHO) as a next step in sustainable value creation. Research in international business (IB) has not leveraged the rich insights of social hybrid scholarship. However, multinational corporations (MNCs), the focal actor of IB, excel at organizing across borders and social hybrid organizations at organizing for dual purposes. This thesis brings together the generative potentials of those organizational forms, multinationality and hybridity, to empirically and conceptually investigate the MHO as an organizational form that features multinationality and hybridity at its strategic core. The simultaneous creation of commercial and social value results in sustainable value across borders. The findings suggest that the MHO shows high generative potentials. It is, however, inherently challenging to organize, due to its multinational and hybrid character. This thesis expands IB in the areas of social value and organizational forms, and the social hybrid debate in its emerging international dimension.
