The Lineate development team built a supply side platform from scratch for 33Across. Previously, the 33Across platform helped publishers make money from their ad space by connecting with a variety of supply side platforms (SSPs). The problem? These third-party SSPs weren’t driving enough revenue. So, 33Across needed a way to connect to demand sources directly using their own SSP to increase margins, improve user experience for client audiences, and cut the costs of paying middle men SSPs.
