I billed myself as a startup specialist with a background in physics so projects either went into full production and I left or they failed and I left, either way I was gone. The security printing company ended when the founder had a bout of anxiety brought on by hiring good people who did their jobs, classic "insecurity". He panic attacked in front of the main investment bank's rep, not good. I knew we were done as I watched him throw a fit in a full board room meeting. Too bad as we were on target for all our projects and had won numerous awards and I spent tons of time getting us ready for a move to a full production plant. I stopped going in when the checks stopped which was longer than expected, the move never happened.
The other shop was in Saudi Arabia. The owner built a good sized conventional printing operation and made the jump to a full digital facility but none of his new stuff worked and he was going bankrupt. An associate who was the sales specialist for one piece of equipment happened to sit next to him on a plane to Vancouver. The guy was certain that the gear didn't work and he had been screwed. Well the guy who was sitting next to him was responsible for hundreds of installs and someone he knew (me) had experience getting everything else he had working. We went there, got everything working (that's my desk in the photo above) and expanded the shop many times until he lost interest. People with lots of money and not much else are susceptible to chasing shiny objects when you need them to focus.
I just looked at the Barco pages on wikipedia, (thanks luchford) and a lot of that information is wrong or is written to not include what I knew about the company. I don't have any documents to prove my accusations so don't want to edit it but Barco made lots of unix hardware right up until the end and I don't see any reference to it and they had lots of tech relationships with manufacturers of other specialised equipment. We had a bunch of it so I know it existed. And there's no mention of their work in gravure printing which was major.
When computing was controlled by people of science it was a good world to work in. When accountants took over I just wanted out. Here's one example, when I had a problem with unix gear and I'm not just talking Barco here I had a list of phone numbers of engineers who I could call and get immediate answers, did anyone improve on that today? If I had a problem with a "system" I could get reps in from all the vendors for a meeting and actually solve the problem, has anyone had a rep from Microsoft at a problem solving meeting? I had a VMS server that hadn't been rebooted in almost ten years! I had contact with the guy who last rebooted it and he would review my proposed changes before I implemented them, for FREE because he liked the machine and was proud I was still on his "session". You don't get much pride when all your gear is designed to last 18 months.
