The platform we're building today exists to answer one question

how do we keep Maintain X engineers shipping fast as the org grows from where we are now to 2-3x the size?

Today, spinning up a new backend service, getting it to production, and operating it involves too many manual steps, too much tribal knowledge, and too many decisions each team makes in isolation.
