Special unique products
Once again we have gone to a company, that makes something completely new. The problem with it mostly is the lack of profit and probable bankruptcy. Marcus comes to the rescue and funds the future. Once it is done, and he has fixed the owners mental issues, it is all wrapped up with a potential future. This usually comes with major expansion, possible franchises, new business connections and different products.
The one detail that is lost completely almost every time is the original concept of the owner. Instead of adjusting the mistakes and continuing on to success, he basically eliminates the past and shows them how to make money. He could just tell them up front that their idea was bad to start with. Even the name is changed to not confuse it with anything special.
Marcus turns one of kind ideas into mass market boredom.
