Well, this is what happens when a company of IT geeks grows and takes on managers and sales drones who haven't a clue of what een sql query is...

It's ants vs grasshoppers all over again ...
management and sales are mostly living of the labour of the worker-drone programmers etc ...

will they sue when you start on your own?
Sure they will, because in the first place, their entire development team (and by that their main income) just took off, and secondly they are doing the same as before, but again for themselfs...

My advice ... If you're stuck with a non-compete clause, this mostly is for a year or so ...

So make sure you only start selling your product AFTER this period. Also, don't start a company yet, just do nothing that gets you on their radar... But work in "secret"...

After this period, you burry them ...

Well it's a hell of a lot safer then cloning huge dino's ... Maybe clone them and put them right into a theme park ...
