About Us

RSN8 gives marketers a new way to optimize their content for their specific audience without giving up on human creativity. With RSN8, brands can drastically improve the effectiveness of their messaging and measurably increase their revenue (10%+ for an A/B tested campaign), all the while saving on expensive customer surveys. We achieve this by leveraging state-of-the-art AI-models to predict how content resonates with the companies' specific target groups: marketers get immediate and concrete feedback on how to improve their creatives for greater impact. To ensure all of RSN8's models stand on a firm scientific foundation we work with renowned researchers from Harvard and LMU. No more human guesswork, just science-backed insights.
