The job is simple — very simple. More than with any other job, the responsibilities of a CEO diverge from the duties and the measurement. A CEO’s responsibilities: everything, especially in a startup. The CEO is responsible for the success or failure of the company.
The CEO’s second duty is building culture. Work gets done through people, and people are profoundly affected by culture. A lousy place to work can drive away high performers. After all, they have their pick of places to work. And a great place to work can attract and retain the very best. Culture is built in dozens of ways, and the CEO sets the tone. Her every action — or inaction — sends cultural messages.
