“(unknown current hero -- generic composable content platform pattern)”
"Composable content platform" is architect jargon. The marketing director who signs the contract sees a meaningless phrase. The developer who would champion Contentful internally already knows the product -- they need ammunition for the budget conversation, not a category label.
“One CMS, every channel. Manage content once -- publish to web, mobile, kiosk, and whatever comes next.”
Names the pain (managing content across channels), the solution (manage once), and the future-proofing (whatever comes next). Both the developer and the budget-holder understand the sentence.
