That part just boggles my mind. How can you go from revenue of 30M to 713M in a single year and not have wound up with any profit? Their revenue has grown so fast that I simply cannot imagine being able to greenlight enough spending [1] to get rid of it all in such a short amount of time.
[1] intelligent spends that is; frivolous waste notwithstanding.
My boggling is more at the challenge of intelligently doing that spending than simply tabulating it. e.g. how do you intelligently hire 20 people a workday, every workday for an entire year, when you were a 100-person company?
That 713M "costed" 433M (seems to be that what goes to the companies advertising via groupon). Then theres 263M on "marketing", 233M on "selling, general, and administrative", and 203M on "acquisition related". The link has more detail on what each of these means.
