Novus Partners also does Scala. We've even got a few Python guys coding in Scala. It's just a language with the JVM ecosystem to back it up. Python has it's own ecosystem and for numerics, access to LAPACK and UBLAS is pretty awesome, I must admit. That said, both can exist fairly comfortably in a company and can be used for different purposes.

I like Python for prototyping, algorithm validation, and just to hack on. I like Scala for damned near everything else. (Also, Adam is going to be open sourcing what is essentially a Scala clone of Pandas but statically typed and with comparable performance.)
