One of the things that's kept me so interested in the company over the years is how he can both seem very reasonable and at times delusional. The reasonable part has led him to relationships with solid businesspeople like Bruce who weren't able to pick the unrealistic comments out of Marc's legitimate business knowledge. I invest in a lot of small companies and learn more from stories like this than from successful companies.
He does have a felony conviction on his record from the 1990s. That's not necessarily something I would hold against a person because I do believe that people can have the ability to change their lives or could have just got caught up in bad circumstances but Marc's case wasn't for a barfight or something like that, it was business-related: him and his brother were convicted of extorting their victim to gain use of a catering license.
