The size of the check that an investor is willing to put in. I tell founders that i work with, don't even think about doing a a price round unless you're in the millions. One of the reasons i've gotten really successful in the last half of my investment career, is i study the revenue numbers of the companies. When i see somebody growing twenty per cent a month for three or four months, i go check out the product. And one of them might jump the fence and take the whole inke as they're greedy.
