Every app agency needs a visionary at the top responsible for capturing and executing the vision of the app. This person must have a solid technical background, extensive knowledge of the targeted industry, great managerial skills, and a keen sense of responsibility.
The strategists should be experienced in a variety of platforms, such as marketing background and knowing the different platforms. Furthermore, because it involves dealing with apps they should also have knowledge of Java or C++ for Android and Objective-C or Swift for iOS.
