First, you need to get "social proof". Getting accepted into Y-combinator is a very good one. Or if you already sold a company then you are golden. But if you are super smart working in large tech company such as Yahoo! for 15+ years - good luck. Especially if you are over 40. When you are 40 it is easier to convince Discovery Loan to give you 100K loan than seed round from any VC.

Second, you should not have any revenue or god forbid any profit. You might think that is needed but actually revenue and profit are bad for raising money: investors will look your numbers and make projection based on these numbers. It much easier to sell "blue sky" than business with actual revenue and profit.

So to raise money:

  1 build "social proof", 
  2 make powerpoint presentation, 
  2 go raise money
