Krime is it's own corporation, and numerous attempts at buying it out have ended with the Suit in charge of the buy out, or "buy out", disappearing.
Sometimes pieces of them can be found. Typically a head. In a Stuffer Shack plastic bag.
It is heavily implied that Krime is actually owned by a retired group of Basque Shadowrunners who made "The Job", the one that lets you do whatever you want, and they wanted to make guns that were properly troll-sized apparently. Or, that's what they try and pass themselves off as. The truth, well chummer, it's Shadowrun, even Plan 9 doesn't know all the truths.
