An account executive works as a liaison between a company and an advertising agency. Most often, these workers attempt to sell an agency's services to targeted clients by performing preparatory work in the hopes of signing the client company. Working as an account executive means performing extensive research and learning all about the clients' products, marketing goals and needs. Often, account executives choose a target group, create an advertising concept and develop a promotional campaign after becoming familiar with the company's product. Account executives work with a variety of departments, such as the marketing, copywriting and art departments, in order to create innovative advertising and marketing campaigns.
