I work on a product at Salesforce.com that uses Angular.js for our frontend. So there are definitely big companies like us that use it. We are doing a rewrite of our frontend and evaluated Ember, Backbone, and Angular. Our frontend devs liked Angular best so we went with it. We're about 8 months into the rewrite and it's gone very well so far. Shameless plug: we're also hiring Ruby and Javascript devs local to SF as well as remote. My email is in my profile.
