We've been using our Meteor-based, multi-tenant CRM/talent-management app in production for several months now. It's called Exartu and is open source hosted on github. We originally wrote the app using sql and signalR and as we've done with many of company's (Tempworks Software) products, but we switched in no small part for the real-time reactivity offered natively in Meteor and the productivity gains from its packaging system. At one point we used Knockout for all our binding but switched when Meteor's Blaze matured. The speed and simplicity of the templating engine coupled with the fact that js is used both client and server side reduces the learning curve as we add devs to the project. Contrary to many comments here, I've really enjoyed using mongodb and find it fast and eminently suitable for a problem domain like CRM that is constantly in transition. Our biggest problem with Meteor was that as a new platform there were no enterprise level apps to model after. We made the app open source (github->Exartu) in hopes to change that, and we welcome critiques to it.
