Review on Hayas by Michael Hall

I like that you can use your own data for advertising purposes without having to pay third parties. It's not very intuitive at first but after 10 minutes everything becomes clear and it works well (or almost). They could do some updates so we get more suggestions when choosing an ad format or if there are no ads available during certain times. I also have problems with their interface whenever they update something - sometimes this goes really slow which makes me lose time waiting while my computer tries to catch up. Some features don't seem updated anymore as well. We're using them mainly because of our clients' brands being displayed across different platforms such as Facebook / Youtube etc.
