In this innovative unscripted series, Jimmy Fallon starts a premier marketing agency and fills it with the most creative, clever, and competitive go-getters he can find. Legendary marketing executive Bozoma Saint John serves as the On Brand Agency's Chief Marketing Officer, mentoring the creatives and evaluating their work.

In each episode, the creatives work with a major brand in need of a big idea for a high-priority campaign - from creating earworm jingles and unbelievable activations to producing the most quotable commercials and must-have merchandise. Only the best ideas move on to proof of concept and the opportunity to see their campaign brought to life on the national stage.

In a final assignment, one visionary is named the best in the business, given a cash prize and provided the experience of changing the cultural landscape.
