This is just my subjective opinion, but that seems a bit overvalued to me. I have no doubt that hipmunk will be successful, but after raising that amount, the amount of success they must see is going to have to be pretty large. If they had not raised that amount, a 10 mill exit would be great. But if you raise 7 and exit for 10, it doesn't look very impressive.

I hope they gain the technological or businesses assets to make them worth tens of millions, it seems like that is what would guarantee such a large raise.
