Hipmunk

Hipmunk is an online travel company providing users with hotel deals and flights results via a website and an app. In practice that means designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Mobile Apps, Online Portals and Travel. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Hipmunk is based in San Francisco, California and founded in 2010. Their site is hipmunk.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.
