I also think that some people are better able to get funding and make up for other inadequacies in their concept or implementation thereof by leveraging their in-person skillset.

Obviously, being good in-person and being able to convince a VC of your competence is a skill that likely correlates well to success with a startup, but I doubt that it is one to one.

Just like there are a lot of excellent engineers that get passed over frequently because they aren't good at white boarding, or interviews in general.
