JuliaFin actually includes a bunch more stuff on top of JuliaPro/JuliaRun that is finance/banking/insurance specific. We have a really cool library called Miletus - which is a contract specification language based on a paper by simon peyton jones. Also, it will include JuliaDB, Bloomberg connectivity, etc.

So, not more money for the same stuff, but more money for a lot more other stuff. Some of these components are proprietary, but many are open source.
