Execujet basically manage acft and I am not sure if they own any, that said, if a owner purchases or puts his acft on with Exec to manage and the owner doesn`t have crew they will typically source crew for that acft if they don`t have rated pilots or pilots available from their own pilot pool I know they do have permanent crew and a CP but you need some jet ratings and jet time. On their website you can see the hr requirements but it`s not a easy company to get into. Good luck!
