Door 6

Door 6 is a SaaS-based platform that focuses on developing interactive games for smartphones. In practice that means designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. They also list iOS, Mobile and Video Games, so expect those to show up in the feature set. 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.

Door 6 is based in Madison, Wisconsin. Their site is door-6.com.
