I love how easy it was to use since my background in sales/marketing lends itself well with this platform! The interface could be more intuitive but that's nitpicking at best when we're just starting out as an agency (we have some experience).
We are using fetchers primarily because of its ability to pull detailed information regarding our customers' products which allows us better insight into their marketing strategies. This helps drive strategy decisions around what types of content should go where within social media channels or emails sent via automation software like MailChimp - all things related to customer acquisition & retention efforts.
