FrostWire

FrostWire is an open-source free file sharing application supported by a worldwide community of users. The job it does: designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. Related areas on their profile: iOS, Mobile Apps, Music and Video. 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.

FrostWire is based in Miami, Florida and around since 2007. More on frostwire.com.
