Alexis says it was between 10-20M: http://www.inc.com/magazine/201206/christine-lagorio/alexis-ohanian-reddit-how-i-did-it.html http://www.inc.com/magazine/201206/christine-lagorio/alexis-... The same article says there were two original founders, and two later founders, which kind of tells me they didn't split that $10-20M evenly. Even if it was all cash with no sort of vesting or earn-out, and Aaron got 10% (sounds about right for a non-true-founder), that would only be $1-2M, and that would be taxed down to six figures. All my financial speculation is based on what I find on the internet, though I have met Aaron a couple of times.
