GBGood for scaling ads Pretty fair pricing model, and they have a lot of technical knowledge about ads for Facebook. They are also guest speakers on Shopfiy's webinars here and there, so feel free to watch their webinars first before testing the waters.

GBhesitant at first, but became a great experience we've been through a few agencies and were hesitant to try these guys after 3 failed experiences. first week was a slow start, but by the 4th week things were working...we're a few months in now and we're happy with them.
