Reelevant — Only 1 out of 10 people interact with marketing messages. Content is the bottleneck of personalization, not data. Personalization doesn't work because data are used to create targeted campaigns. Data must be used to create content because content creates interactions and drive conversion.Why: create content for people, not for campaigns(visual is the key to emotions) How: on-demand, when the user request, at the opening/reading/exposure (Pull content vs Push marketing) What: end-to-end widgets solutions like Live content, Individualization, Content Automation, Optimization, etc.Our visual content platform accelerates revenue, creates content based on any data (behavioral, contextual, etc.) created on the fly at the moment of exposure (on any channel (email, web, push notifications, in-app messages, etc.). We take advantage of existing data sources, nothing to create, we supercharge your marketing stack. Our data-driven Content Engine translates data from any source into on-demand visual content in milliseconds for each people.We believe in a new way of thinking about messages by shifting the paradigm of push marketing to transform any data into on-demand visual content. One unique content is created for each people on the fly at the moment people decide to read them (pull content), instead of when marketers decide to create them (push marketing).People are not data points, people don't buy products, they buy emotions. On-demand visual content is the new game!
