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.

Her every action — or inaction — sends cultural messages.
