Description: Trantor helps companies increase their conversion rate of their campaigns, through psychometric segmentation. This is based on segmentation through the psychological traits of their potential customers. Our software detects implicit (hidden) interests that are directly related to personality traits. By introducing specific predefined interests in Facebook, we are able to reach people with certain psychological traits. The possibility of segmenting our campaigns based on the psychological profile of the audience, enables us to communicate a specific message or key aspects of the brand/ product, that will connect emotionally better with the target. Thanks to this new way of segmentation, we are able to increase the conversion rate of a campaign up to 30%. We do it via the usage of state-of-the-art tools developed for different areas of the artificial intelligence (AI) field. In contraposition to the traditional approach of defining target populations based on stereotypical interests, our proposal tackles this problem from the personality analysis perspective. The first component of our methodology builds on the work developed by Prof. Michal Kosinski, who found interesting and strong correlation between personality traits and interests of individuals based on the OCEAN model of personality.
