There are some companies who use kotlin for server side with Spring or Ktor

Not really, some people mentioned it before, that their company is using kotlin for non-moblie development

I know of teams within Amazon who use it on the backend

Just working on a project with a big car manufacturer in Germany where we use Kotlin and Spring-Boot for the backend

Can confirm, our team also made a transition about a year ago and we write our AWS microservices in Spring Boot and Kotlin almost exclusively now
