EntitySource

EntitySource is open to work with many companies on customized applications. The job it does: designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

EntitySource is based in Palo Alto, California. You can read more at entitysource.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Get the renewal terms in writing before the first invoice.
