Purpose Building on the research program of Dillard and Brown (2015) and Dillard and Vinnari (2019), specifically related to an "ethic of accountability," this paper recognizes accountability systems as key to how organizations conceptualize their responsibility to society. The objective is to explore how managers of hybrid organizations conceptualize responsibility and the role of accountability systems in their conceptualization. Design/methodology/approach This paper studies hybrid organizations that are for-profit entities with explicitly recognized non-economic imperatives. Semi-structured interviews are conducted with managers of organizations that pursue certification as a B-Corporation, often in conjunction with a legal designation as a benefit corporation. Findings Managers of the hybrid organizations evidenced a broader responsibility logic that extends beyond responsibility to shareholders. This pluralistic orientation and broader set of objectives are expressed in a set of certification standards that represent an accountability system that both enables and constrains the way responsibility is understood. The accountability system reflects a "felt" accountability to the "other" manifested, for example, as generational accountability, with the other (re)created relative to the certification standards. Research limitations/implications Certifications and standards represent accounting-based accountability systems that produce a type of accountability in which the certification becomes the overall objective nudging out efforts to take accountability-based accounting seriously (Dillard and Vinnari, 2019). At the same time, the hybrids under study, while not perfect exemplars, incline toward an ethic of accountability (Dillard and Brown, 2014) that moves them closer to accountability-based accounting. Originality/value The findings reveal perspectives of managers embedded in hybrid organizations, illustrating their experiences of responsibility and accountability systems in practice (Grossiet al., 2019). The insights can be extended to other hybrid contexts where accountability systems may be used to demonstrate multiple performance objectives. We also recognize the irony in the need for an organization to be required to attain a special license to operate in a more responsible manner.
