Aster addresses the objectives of governance, collective performance and hybrid collaboration by focusing on rituals. It is a collaborative software for taking, structuring and visualizing notes for effective strategic meetings and a better follow-up of actions and decisions. As a Microsoft partner, it is fully integrated into the Teams meeting interface. Aster intervenes in the 3 stages of a ritual. It automates the preparation and maximizes collaboration, makes the animation fluid and rhythmic and automates the sending of the minutes and the follow-up of actions and decisions. More than 55% of our users' meeting preparation is automated. Overall, our users spend up to 30% less time in meetings and have a lighter mental load.
