Portuguese startup based on our own version of AOLserver, based on the same principles of Apache plugins + Tcl + C, basically Rails before it was even an idea.

We got acquired, by another bigger Portuguese company (Easyphone), which alongside another acquisitions became Altitude Software.

Our stack was used to some of their products serving multiple top tier companies in Portugal, we created an IDE for our tools, written in VB.

Supported all major UNIX flavours and Windows NT/2000.

Eventually scale problems happened and we were looking how to tackle them while avoiding rewriting everything in C, as MSFT partner we got invited to try out .NET pre-public announcement, so we decided it was a good opportunity to rewrite our product in this new .NET thing.

Some of the team members eventually took all these lessons and founded OutSystems.

The amount of histories of porting code prove otherwise.

Note I am not pushing away dynamic languages, only those that don't have a JIT/AOT as part of their canonical implementation.

Common Lisp, Julia, JavaScript, PHP (7 and later) are all invited to the party.

Meanwhile maybe JRuby or PyPy will eventually get more community love, instead of being the black swans.
