It's certainly recognized by Digital Ocean since they are sponsoring Nim for hosting all the nim-lang.org services.
Otherwise you have a couple of AWS related packed on [nimble.directory](https://nimble.directory/search?query=aws) but Nim presence is still tiny and experimental in many companies. Assuming you use Nim to learn programming language concepts, I think using Nim will give you lots of knowledge that can be transferred to C, C++ and Rust without the hassle of doing your own memory management at the start (similar to Go I'd say). What you might struggle with is the lack of libraries but that can be remediated by wrapping a C or C++ library. In terms of niche or not backed by big name languages, Nim is probably one of the most well-known ;).
