Company Structure
Pro tip: In many Latin American companies, the top executive is called the Gerente General rather than a CEO. The title roughly means "chief executive", and you will see it on business cards and org charts.
Note that empresa and corporación are not interchangeable. Empresa covers any business from a food stall to a multinational, while corporación implies a formal legal entity with shareholders and a board. Calling a small family shop a corporación sounds unnatural to native speakers.
