SignSchool

SignSchool is an online learning platform that offers American sign language services. The job it does: designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. They also list E-Learning, Education and Mobile Apps, so expect those to show up in the feature set. 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.

SignSchool is based in Princeton, New Jersey and founded in 2014. More on signschool.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
