makes you want to take on VC money with those kind of perks. :) we have a small amount of angel money but as founder I took half salary so we could spend a few bucks on decent monitors and task chairs for the developers. they could be better but we had to cheap it this first round.
I wonder how many hours a day Asana expects developers to crunch? My guys aren't addicted to Facebook/Twitter and we don't have office distractions or other 'perks'. We work all day in the zone, and I usually cut them off at 6pm and force them to go home so they stay mentally fresh.
