SixString

SixString is a mobile application that engages in sharing events, audio and news with a Guitar-centric community. The job it does: designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Music. As a very small company team themselves (1 to 10 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.

SixString is based in El Segundo, California and founded in 2011. You can read more at sixstring.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.
