If by one of those you mean a solopreneur who doesn't have any junior devs to yell at then yes. If I wanted to use static types I'd use an actual statically typed language with all of the performance benefits (Go, Java, Rust, Haskell, Ocaml, etc...).

Using a dynamically typed/interpreted language with type annotations is literally the worst of all worlds...
