Our take

The landscape of advertisement has changed dramatically over the years, with campaigners now needing to deliver video advertisements quickly and efficiently across a vast range of digital platforms. This is easier said than done, however, with the range of existing advertisement management platforms being slow, segmented, and antiquated.

Basis provides a digital marketing platform that allows users to manage advertisement campaigns across a variety of digital platforms. The demand-side platform provides a variety of automated tools that facilitate publishing quick and large-scale changes to campaigns, in addition to providing analytical insights and other innovative assistance tools.

Whilst other DSPs are providing digital marketing tools for advertisement management, Basis stands out by providing an all-in-one, fully unified platform. By covering all the bases, the company claims to be the first single sign-on media automation platform that can deliver to the variety of channels and vendors required in modernized advertising.
