CallVU

Callvu is a mobile digital engagement platform that focuses on storage transformation and CX automation services. The job it does: designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. As a small company team themselves (11 to 50 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.

CallVU is based in San Francisco, California. More on callvu.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
