The platform is very user friendly and easy to use. The ability to be able to track and monitor all advertising spend is great. The dashboard is not as clear as I would like and sometimes takes a while to load up. The platform is great for all sizes of advertisers. We use Admixer to manage all of our advertising spend. It allows us to track and monitor every purchase that we make. That it integrates with multiple DSPs, so that we can easily manage our inventory across them without having to code separately in each one. As well as integration with 3rd party tools like Vungle and Moatify. Their support team are fantastic - they were quick to respond when I had issues integrating my tool with their system. For me personally, nothing! It has been working perfectly since day 1, which was almost immediately after launching.
