MacRuby was announced in 2008 by Apple with the purpose of offering a modern and dynamic environment to develop full-fledged and efficient applications for the Mac. Since then, MacRuby saw a series of significant releases and in 2010 became a stable and viable alternative to Objective-C.
In 2011, Apple released the Mac App Store, which welcomed apps written in MacRuby. Later this year, Apple shipped OS X Lion with features written in MacRuby and O'Reilly published MacRuby: the definitive guide.
In late 2011, Laurent Sansonetti, MacRuby's creator and lead developer, decided to leave Apple in order to push Ruby where it has never been: Apple's mobile operating system, iOS. He decided to create a startup, hoping to make a living doing what he loves.
It's 2012 and Ruby is finally available on iOS.
Laurent is the founder of HipByte and lead developer of RubyMotion.
He worked at Apple for 7 years as a senior software engineer, on both iLife and OS X. A long time rubyist, he created and still maintains the MacRuby project. In a previous life, he worked on IDA Pro and was an active contributor to RubyCocoa and GNOME.
Shizuo, better known as Watson, is a software developer from Tokyo, Japan.
Watson joined the MacRuby project in 2010 and quickly became its most active contributor. He works on the RubyMotion toolchain and is also involved in RubyMotionJP, an effort to promote the project in Japan.
Sacha Greif is a user interface designer who's worked with startups such as Hipmunk and Codecademy.
The RubyMotion logo has been designed by Stephanie Sansonetti and Henry Daubrez.
His background includes peer-to-peer software, wireless web, workflow, and pen computing. Rich has been using Ruby in production systems since 2002 and has contributed to many Ruby projects over the years including RubyGems and starting RubyForge.
He is constantly in demand when it comes to consulting and speaking, and is considered by many to be one of the main go-to guys within IBM for advice on blogging, social media, and technical marketing.
