GraphQL has also seen production usage outside Facebook, in a project for the [_Financial Times_](https://www.youtube.com/watch?v=S0s935RKKB4) by consultancy [Red Badger](http://red-badger.com/).

 “GraphQL makes orchestrating data fetching so much simpler and it pretty much functions as a perfect isolation point between the front end and the back end”
