Companies that use server-side Kotlin

Hey all, just curious for some research at work:

Do you guys know enterprise-grade companies that are using Kotlin server-side (meaning other than Android dev )? If so, to what extent? Would you be willing to share the name (here or in PM)? How is Kotlin being used? I would love to do some research and digging on companies currently adopting Kotlin over a more time-tested tech like Java or .NET! See if I can get my company on board!
