None of us is as smart as all of us.



We’re specialized in web applications build with Ruby on Rails. We practice agile development techniques in order to deliver prototypes, proof-of-concepts and high quality products. Dovadi was co-organizer of the Ruby and Rails conference in Amsterdam 2007. We share our knowledge through open sourcing our libraries (if possible) and through in-company workshops. Dovadi was an active sponsor of the Dutch Fablab community and initiated Ruby Co-op.

The most recent open source project, an energy monitor Observi with the Ginkgo energy gateway, which was launched in May 2013.
