After that they have a "team of more than 4,500 employees includes LivingSocial professionals in every city where we offer deals"[1], 19 offices[2] plus another office/shop thing called 918F Street[3] and they have a 5 month training program[4] which adds costs to their hosting, software design etc.
Once they've paid out for its 4,500 employees, offices, hosting, software design, training programme, legal costs etc they also have significant marketing costs as well. Although companies like Ampush have helped them to lower it recently[5]

My guess though is that their major cost is customer acquisition. That seems to be the norm in this space. They're buying customers for $5 and making $2.50 off them (numbers theoretical, as an example) hoping to make the rest back later when they've won the market.
Living Social is private and can do whatever they want, but they probably are using net if they're comparing themselves to Groupon. Otherwise they're making themselves look half the size when they are really a quarter, which I suppose could be purposeful.
1. Many here seem to feel that taking 50% is unfair to their merchant partners. Yet, they are nonetheless struggling to turn a profit
2. Like any other coupon, LS deals run the risk of un-use. Speaking for myself, I have forgotten about at least 4 separate deals, and am not an active "daily deals" consumer.
How can LS ever be profitable? It feels like they are already absorbing as much net revenue as they can, and have the deck as reasonably stacked as possible. Is it a question of needing to run leaner (they do spend hand over fist, in my experience)?
Earlier in its existence, marketing was also a huge cash sink for Groupon. This has improved for them as their product matured, but it's likely that Living Social is still spending a huge amount here, too.
