Is the Echometer Retrospective software also suitable for several teams or projects at the same time or can it be scaled?

Absolutely. Especially if you want to work with multiple teams, Echometer might be the best retrospective tool. Echometer is scalable for numerous teams and parallel projects - ideal for organizations with multiple Scrum or project teams. Workspace settings, for example, help with this, allowing you to create dashboards across teams and even use a Workspace Health Check to survey across teams.
