To be fair, there are a LOT of early employees at Facebook that got churned through, or who didn't make it to the executive tier. Chamath almost got churned through, but he hit it big on the Growth team. That's the difference between an early employee with $10M and an early employee with $500M.

Moskovitz (now Asana), D'Angelo (now Quora), Vernal (now Sequoia), Bosworth (still at FB on hardware/Building 8), Cohler (now Benchmark), Hammerbacher (now ?), Chamath (now Social Capital) ... those are some of the standouts off of the top of my head, out of hundreds of early employees.
