Always awesome to see another production Ember.js app in the wild.
On a personal note, the team behind Confetti also organizes the NordicJS conference in Stockholm. In addition to running one of the best JS conferences in the world, IMO, they are also some of the nicest people in the community. As a NordicJS attendee, I've been "beta testing" Confetti for some time. It's a great product and I wish the team all the best.
