David created Ruby on Rails, the open source web framework in 2003. That would pretty much define most careers but he is also founder & CTO at Basecamp.
(Formerly 37signals – a $100 billion private company though achieving this valuation was probably the easiest thing he has done).
He has thoughtful opinions, is a best-selling business author – Rework, Remote: Office Not Required, Agile Web Development with Rails.
He is also a Le Mans class-winning racing driver, hobbyist photographer, and family man.
