I think their methods can only be as good as the honesty of the input. Depending on how they validate, this company might be an easier target for people who will just cook the books on their scores. I'm hoping that they thought of that ahead of time.

Far as character, there's an old legend where JP Morgan was asked by Congress on what basis he lends out money. He reply was the person's character, not ability to repay. His reasoning in the story was that people of poor character, but having the money, would make up any excuse to avoid paying. Whereas people of good character would do everything they could to get the money and pay up. Realistically, ability to pay is a huge consideration but the story's lesson about character was wise. Interesting seeing it in action and automated to a degree.
