The lesson
State the challenge and the idea briefly, then let the work itself, shown large, do the persuading.
"Uber For Business" tops a short intro and film player, then short blocks headed The Challenge and The Idea ("Show that we deeply understand the trials and tribulations of the travel manager"). The rest is mostly visuals: a type-and-color tile, a black 24/7 headline panel, a row of social cards, a pull quote and a subway-platform ad.
Don't copy the dark navy art direction or the exact section names; they suit a creative agency. Keep the ratio of short context blocks to many screens of finished work.
