Swappa

User-to-user marketplace for consumer tech. That is the short version of Swappa. In practice that means designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Android and Mobile. As a small company team themselves (11 to 50 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.

Swappa is based in Kansas City, Missouri. You can read more at swappa.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.
