That is the untrue statement of the decade. In my experience, VC and angels are little more than lucky, but deluded to believe otherwise. Or corrupt, and using you to hide their activities.
Many VC's may very well be primarily lucky, but that does not mean that the companies they put their money on are not more often than not in a position to grow faster with their investment. It's just that they are still also at high, and often substantially increased, risk of failing fast. Not least because an investment is often used to execute strategies that substantially increase the burn rate.
