A Chief Executive Officer, or CEO, is the highest-ranking executive in a company. They are responsible for making major corporate decisions, managing the overall operations, and acting as the main point of communication between the board of directors and the company's operations. The CEO sets the strategic direction and ensures that the company meets its goals. CEOs often have a background in business management and leadership. They work closely with other executives, such as the Chief Financial Officer and Chief Operating Officer, to implement policies and drive the company’s success. Their leadership style can significantly influence the company culture and performance.
