"I decided to join Heroku because they are committed to openness and developing Ruby further," said Matsumoto.  "I want to make the Ruby development experience even richer, more natural and more productive than ever for all Ruby developers."

Heroku was founded in 2007 by application developers for application developers, with the goal of making the deployment and management of next-generation cloud apps as easy as their development. The application platform features a workflow and interface designed around how developers work. Because the platform is a service, there are no virtual machines to manage, no software to install, and no hardware to manage.
