The lesson
Put the customer's before-state and the number it collapsed to in the post copy, so the case study sells before anyone opens the document.
The copy above the creative reads "Canva ran 10+ card programs across 190 countries with no single view of spend. See how they consolidated to one." The document cover splits "CASE" and "STUDY" across an orange gradient, with the Brex | Canva logo lockup between them and a bar reading "How Canva consolidated 10+ card programs".
Skip the Canva figures; you need your own customer's numbers, with permission. Keep the structure of a named customer, a messy starting count, and one resolved outcome.
