The ability to have multiple ads in one page, no need for 3rd party extensions like the rest of the competition, good UI and easy to use. Not many features, but I think that's one of their core values. We tried other similar platforms and ended up choosing spring serve, it was a nice choice, nothing in particular to dislike. Ad serving is important for our business so we needed a solution that will satisfy our needs and provide us with great ROI. I like that it's fairly easy to use and has a lot of features for publishers. The interface is not very intuitive, but getting used to it was simple enough. All in all, I think it's worth trying out if you're looking for more advanced ad serving software. It does what it says on the tin - we can serve ads and track them across multiple platforms (iOS, Android, desktop). We have been able to streamline our workflow with the help of this tool.
