A Co-CEO is a leadership structure where two individuals share the role of Chief Executive Officer in a company. This arrangement allows both leaders to bring their unique skills and perspectives to the organization, potentially enhancing decision-making and strategic direction. Co-CEOs often collaborate closely to ensure that the company's vision and goals are met effectively. This model can be beneficial in large organizations or during transitions, such as mergers, where different expertise is needed. However, it can also lead to challenges, such as overlapping responsibilities or conflicts in leadership styles. Companies like SAP and Whole Foods have successfully implemented this approach.
