We (Zyxware) started working on Drupal around two and a half years ago. I had selected drupal as the platform to work with after countless hours of review of other solutions. Ever since we started working with drupal, I used to pull up Drupal Association and toy with the idea of joining the association because I wanted to do more than contribute code to drupal. Finally I took the plunge and signed up Zyxware as a formal member of Drupal Association
