Which type of agency would likely focus on quick and inventive creative work?

The correct answer is focused on a creative boutique, which is a type of agency known for its specialized approach to creative work. Creative boutiques typically emphasize innovative and unique concepts, often operating with a smaller team of highly skilled professionals who can pivot quickly and generate inventive ideas. This environment fosters creativity and experimentation, making them ideal for projects that require a fresh perspective or rapid turnaround.

In contrast, full-service agencies manage a broader range of functions, including media buying and client management, and may not prioritize quick creative iterations the same way a boutique might. Media specialists focus specifically on optimizing and managing advertising spend across various channels, which doesn't align directly with the goal of inventive creative work. In-house agencies, while they can be creative, are usually tied to a specific brand's needs and may not have the same flexibility or emphasis on rapid creative development as a boutique does. Thus, the nature of a creative boutique aligns perfectly with the requirement for quick and inventive creative work.
