I have also used Rust in a startup. With one major exception, it has been a huge win.

Rust makes it incredibly easy to write fast CLI tools and special purpose servers. They're solid and pleasant to maintain. Refactoring is easy, and if code compiles, it's normally correct.

The biggest drawback we encountered was when we used Rust for business logic. Business logic tends to be high level and change frequently, and many different people need to touch it.

So we ended up with a split: Most of our business logic is written in popular high-level languages. But for those things which aren't specific to our business, we write lots of open source Rust.
