I'll go off-book a bit.
Ali Zandi - Maybe not for longevity (is he still active?), but for how quickly he made a name for himself in the industry and started producing major sales.
Swetha of DNgear - I actually count myself in the slightly more skeptical camp when it comes to her speed and volume of large sales. Unless they're one day shown to be not above-board, though, I have to think that the speed with which she has obtained this level of success has not been seen in 20+ years.
