Music work runs on handshakes. A producer sends a beat, a vocalist writes to it overnight, and the split gets agreed in a voice note nobody can find six months later. For the Artistto app we designed a working record, not a music product: no waveforms, no neon. Every collaboration is an object with two names, a brief, a role each and a state that moves from proposed to agreed to delivered. The profile is the spine, with releases, collabs and rates in one place. Live on the App Store and Google Play.
