There are a few hedge funds that are quite happy to contribute open-source to the world.

Blue Mountain Capital for example;

https://github.com/BlueMountainCapital

One of their projects is Deedle; an F#/C#-equivalent of the Python 'Pandas' data frame package. Which would in fact make a nice complement to CShell I imagine.

Jane Street would be another choice: http://janestreet.github.io/

Their work on OCaml is currently trending on HN.

There are others I am sure, don't have any links handy.

Who'd a thunk it, hedge funds occasionally produce some social good ;-)

wow, didn't know that. thanks for putting together that list - maybe we should start a list somewhere where people can add, this is definitely super interesting.
