Yvolver

Yvolver provides Loyalty 2.0, predictive analytics services, and advice for mobile app developers. In practice that means designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Alongside the main category they mention Analytics, iOS, Mobile Apps and Predictive Analytics. 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.

Yvolver is based in Dallas, Texas. More on yvolver.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.
