 * Thanks to [Compose Multiplatform](https://www.jetbrains.com/lp/compose-multiplatform/), a modern declarative cross-platform UI framework by JetBrains, developers have full code-sharing flexibility and the ability to share both the logic and the UI.
 * There's no need to introduce a new language to your codebase when you already use Kotlin for Android. You can reuse your Kotlin code and expertise, which makes migrating to Kotlin Multiplatform less risky compared to other technologies.

 McDonald's, Netflix, 9GAG, VMware, Cash App, Philips, and many other companies are already capitalizing on Kotlin Multiplatform's ability to be gradually integrated, as well as its low adoption risk. Some of them opt to enhance their app stability by sharing specific, crucial segments of their existing Kotlin code. Others aim to maximize code reuse without compromising app quality and share all application logic across mobile, desktop, web, and TV, while preserving native UIs on each platform. The benefits of this approach are apparent from the stories of the companies that have already adopted it.
