The upside case is not heroic market share; it is economic repair. Five9 already ships at scale, has real workflow embed, and is proving AI demand inside the
installed base. If cloud migration stays healthy,
Fusion improves partner-led distribution, and AI revenue increasingly attaches to
interaction volume instead of seats, revenue can compound in the mid-teens. I still keep the terminal valuation below best-in-class
CX assets because
bundling and seat deflation remain real.
