Maybe focus on Leadership skills, as in getting people excited to do what you want them to do. Google is full of bright people who are genuinely excited to work for them because they believe in the product, culture etc. What does your startup do? Can you get people excited about it? Can your co-founder? On the other hand, just quit if you don't believe in the venture. You only live once, and in the cosmic scale of things it won't matter if you don't succeed.
