Jet Aviation, Art Aviation, ACM, Privatair, Maleth-Aero, Privajet and probably a few more than that...
As far as Global jet goes, and most other operators for that matter, be careful about what you read here on pprune.
There are always a lot of people complaining here, people who didn't get hired, who ended up on very difficult operations (clients) where working for a specific company turned out to be a nightmare, people who failed to do their job properly and as a result lost their jobs (often feeling mistreated and sometimes failing to see their own part in what happened), people with various agendas wanting to talk down an operator, pilots that seem to forget that companies are just that, companies that exists to make a profit at the end of the year and they are not there to please big (crew) egos etc etc.
The list could be made much longer but you get my point I hope.
