Five Account Executives Sealing Deals in GovCon

When it comes to advertisement and sales, companies employ a wide variety of talent to fulfill their clients’ needs. The creative director, art director, copywriter and graphic designer all play critical roles – but the account executive is the star of the show. Today, their role has become a mix between sales and day-to-day account management, and they are responsible for keeping clients updated on new developments and growth roadmaps. 

Account executives had to immerse themselves in emerging technologies and digital trends even as far back as the 1980s. According to Belo + Company, the role of the account executive was borne out of the need for companies to customize their services to fulfill the nuanced requirements of individual clients.

The Potomac Officers Club – a division of Executive Mosaic – features five account executives supporting clients from the federal government and the military.
