It's really a shame that Groovy is not even in this list. It's understandable as it is very poorly marketed, but it is really a shame that it is not mentioned more, especially on such a forum. For entrepreneurs, it has so many advantages. As productive as Ruby and Python, and yet running on performant Java runtime. Plus, being a derivative of the Java language, it makes it so easy to find experimented developers. It's my personal favorite, and I really think all entrepreneurs with a Java background should give it a try.

Yeah, Groovy really is an awesome all round language. Nearly all the benefits of Java, Python & Ruby rolled into one. And so easily embeddable into any Java app, you can use it just where you need it or everywhere. It benchmarks substantially faster than Python and Ruby for the things I do, and it's really easy to optimize by just dropping into Java for anything that is a bottleneck which is far better than dropping to C and losing the all the benefits of living in a VM.

And don't forget groovy++ to easily achieve java like performance.
