But, as a company you should also focus on your own bottom line - working, stable, predictable, reliable software, a codebase you can still hire people for ten years down the line.

Java and C# are safe bets. It probably won't get you the hip polyglot hype developer type, but I'm not convinced there's any company that thrives on those. Maybe for the POC or MVP, but long term you need a reliable tech stack.

I mean take Google; their backbone is/was C++ and they're moving towards Go, which is even more boring than C++ is.
