If you want to check out agemba before deciding on whether to buy a license, you can get a freebie version.
In this version you will be able to check out the functionality in agemba in a single circle (aka project) and add a limited number of other users.
Note that some features such as tactical planning in sprints, issue tracking, working with teams, etc are not available in the freebie version.
When you request a free agemba account, a confirmation email will be send to the email address you submit. You can then follow the link in the email to setup you account.
