Tamman

Tamman develops rich internet applications and deploys enterprise content management systems. In practice that means 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. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Tamman is based in Philadelphia, Pennsylvania. Their site is tammaninc.com.
