The lesson
Build a customer story around the customer's own engineers explaining why simple beats flexible, and let your product's restraint be the argument.
The title is "Why OpenAI chose Linear and scaled to 3,000 users", above a yellow-blue gradient with the OpenAI logo, then a fact row: Founded, Switched "November 2023", Company size "5,300". Sections like "Simplicity scales" and "When culture meets the right tools" are broken up by large pull quotes from engineers Gabriel Peal and Atty Eleti.
Peal's closing line, "You just have to use it and you'll see. You'll just feel it.", leans on the engineers' earlier case. Keep the engineer quotes and the contrast with feature-heavy tools.
