Trantor is an AI startup that improves the conversion rate of advertising campaigns through psychometric segmentation. Our software detects implicit (hidden) interests that are directly related to the personality traits of the final consumer. Using these interests on platforms such as Facebook, we are able to reach more specific and higher quality audiences, being able to communicate a more appropriate message that connects emotionally better with the profile. Thanks to this new way of segmentation, we were able to increase the conversion rate of a campaign by up to 30%.
