What Rheba Is
An availability network.
Rheba began by solving a real-world coordination problem in music and live booking. It has grown into something bigger: a suite of free tools feeding a deeper system built around groups, identity, and availability.
This company was built from lived frustration. Too many people are trying to manage real work through systems that profit from fragmentation, friction, and dependency.
