Proof of Usefulness Score
Certified Problem Solver

Xoxzo Inc. is a verifiable, long-standing cloud telephony provider in Japan (est. 2007) with valid technological utility (SMS/Voice APIs). However, the submission quality is poor, containing exaggerated traction claims ('most people have used my product') and ambiguous financial data ('marketcap: 2500000', likely referring to JPY Capital Stock, ~$16k USD, rather than revenue). While the real-world business is stable and useful (Team size ~30, verifiable acquisitions like FullCourt Inc.), the score is penalized heavily for the lack of concrete evidence in the submission and the false audience reach claims.
