Once all is said and done (all stock accounted for and distributed on a weekly basis rather than on the vesting cycle) and the expenses above are taken out, there's ~11k left over a month. This is post tax.
The only thing I miss is that there's a lot of diversity in bigger companies you don't find in startups. Here, everyone is like me :D
I'm pretty confident if I was making 2-3x what I am now - I would stay with that. As it stands - I cannot afford to continue living in silicon valley on this current salary.
