About Us:

Xamarin is on a mission to make it fast, easy and fun to build great mobile apps. Founded in May 2011, Xamarin is a very fast-growing VC funded mobile startup with offices in San Francisco and Boston. Over 320,000 developers and thousands of customers use Xamarin because we provide the best platform to create great, fully native mobile apps for iOS, Android, Mac and Windows. 

Xamarin is redefining cross-platform mobile development by unifying fully native app development for iOS, Android, Mac and Windows in a single C#-based platform.  Developers get full access to each platform’s APIs — anything that can be done in Objective-C and Java can be done with Xamarin — and share on average up to 75% source code across platforms.
