Yazta

Yazta is a platform that facilitates secure, dependable, and transparent connections between domestic workers and clients. Put simply, it is about designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Marketplace and Mobile Apps. 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.

Yazta is based in Los Angeles, California. Their site is yaztamx.com.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
