How does it work?
Private and safe space
Zelos is a safe environment that brings clarity to collaboration. As an administrator, you have full control over who can access your project and user data. All projects are encrypted and GDPR compliant.
In March 2020, Tallinn city office mobilised 2000+ volunteers in a matter of days as a response to the Ukraine refugee crisis.
“We needed to get things done and people scheduled without much space for errors. Zelos helped us keep the human touch in teamwork, while still having a very clear and up-to-date overview of the who, where and when. “
– Hannele Känd, volunteer coordinator
