0. Someone I met acquired the charter of a failing Midwestern local regional bank in order to save a ton of cash on moving funds into the us. This person was under 30 at the time. And it was tax and banking legal considering the law firm.
1. Defensibility of a business model is your friend, not you enemy. Look to how incumbents do it. What can you improve on? Just remember that the harder it is for you the harder it is for everyone else. If it were easy, everyone would do it and the competition would be even more cutthroat elsewhere (patents, distribution, connections, etc.).
To potential investors they probably signaled lack of hustle to find creative solutions to get past their current and all other future dilemmas. Without an unique, defensible, competitive advantage there's really no for an investor to throw down on a venture.
