what niche? the niche for online ticket purchasers who prefer gantt-style interfaces? the niche describing the set of customers who rely on a single provider (orbitz.com) for their ticket-purchase decisioning data?
"in a highly monetizeable market"
i'd love see your CAC, CR/CRR, AMPU/AMPC, etc breakdown for the online air ticket space.
"Things are looking good for the team at Hipmunk."
when your only competitive advantage is a gantt-style interface, your outlook is not often described as "looking good".
i wouldn't consider a large base of online fanboys to be a significant competitive advantage in an industry where your competitors are 10 years established and have revenues in the billions of dollars.
"it's a great opportunity for Chris"
in the sense that it's probably better than staying at conde? --sure. in the sense that it will likely result in a significant payout down the road? --again, that's debatable.
