this is absolutely ridiculous. there is next to no seed funding in existence. Let me tell you how the seed market for startups is: imagine you had a orchard, right, but instead of apples it grew dollar bills, and you just had to water them or they wouldn't grow. Under this scenario a guy with acres of dollar-tree bills could not get funding to water them with some kind of farm equipment. That's the state of the start…
Your claim is ... what exactly? I'm not disagreeing - I'm just not following. That revenue is hard to come by for startups? That seed money for revenue-less company is getting more difficult for startups to raise? If so, where? In the US? In California? In Europe? I've never dealt with any structured seed funds, but high net worth individuals that like to kick-start startups still appear to be active in the US...
That there is next to no seed money in existence, for companies, regardless of whether they are making money, and anywhere in the world (including California which by a large margin has the best funding climate for seed rounds.) That if you sum up the total amount of seed money it is next to nothing.
As an exercise you could try to add up the sum total yourself, and you will see it is next to nothing.
