Group income makes it easy for small communities to voluntarily provide a financial safety net for their
members.
<br>
<br>
Members of the group can contribute with monetary (pledges) or non-monetary donations, securing everyone in
your
group with a basic income.
<br>
<br>
Start adding members to see how it works.
