I am not aware of any companies using this framwork.
This is a great grid framwork that drops easily into an existing project. It doesn't have much styling or changing fonts so that means less css conflicts when adding to the existing project. You can alter the columns in the source code to make it as many as you would like, giving you finer control. It has fixed width gutters. very good browser compatibility and takes very little code to start using.
It doesn't have any font or pre-defined css styling
really just the grid responsive design and that you can alter things in the source file so you can tailor it to your project.
