Slido is a platform for interaction with the public, used for meetings, conferences, and events. This enables us, as well as our speakers, to keep public attention, to address questions to the audience and to launch various concepts in a visual way. In addition, we can train participants using live surveys and, in the end, we can extract valuable event data. Sli.Do emphasizes simplicity, and participants can join from any device with a simple code without having to download a specific application.
