OpenSimSim

OpenSimSim is an app that simplifies team communication, employee scheduling and time tracking. Put simply, it is about designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. They also list Management Consulting, 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.

OpenSimSim is based in Carlsbad, California. Their site is opensimsim.com.
