Prototypes /= traction so that almost won't help either. I had a prototype two years ago. Nobody cared. We had an MVP a year ago, nobody cared. Now we are out there actively selling and even then investors are saying: We want to see that you will have 1MM in revenue in the next 12 months before we decide.
A rule of thumb in fundraising is this: "When you don't need money you will be able to get it."
