The lesson
Open a case study with the result as the headline and two oversized numbers, and let the story below justify them.
The title carries the result: "Clay automated 80% of its onboarding tasks and grew 5x in 18 months". Two cards under it read "80" employees added in 18 months and "80%" of onboarding tasks automated. Sections follow: The Problem, The Solution, three numbered features (01, 02, 03) and The Impact.
Don't copy the section names or the three-part count, and don't print a number you can't source. Keep the headline-plus-two-big-numbers block at the top.
