Primis is a global video discovery platform designed to increase revenue for publishers by helping their users discover high-quality video content. The platform leverages machine learning technology to provide consumers with the video content they are most likely to engage with. Its discovery engine is applied in a fully customizable video unit designed to fit natively into any website. In 2021 Primis launched Sellers.guide, an automated tool that compares ads.txt files with sellers.json and provides simple and useful feedback to help publishers and buyers gain insights into who is really buying and selling inventory in any domain. Primis is owned by Universal McCann and the Interpublic Group of Companies.
