I was in charge of all our paid digital advertising for several years before leaving my old job (it's been about 6 months since then!).
They are one of very few companies that makes it easy to create ads across multiple channels from 1 dashboard/UI - which saves so much time! The reporting capabilities were not as robust or intuitively laid out than some other platforms we used previously but they're working hard on this now and getting there!! Definitely worth exploring if you have any questions regarding their services because support staffs around the world can be pretty quick when needed :) We use them mainly for Facebook PPC campaigns though also spend significant amounts using Instagram API daily via both desktop & mobile apps.
