Proof of Usefulness Score
You're In Business

CariGem Mobile presents as a standard local e-commerce operation in Barbados rather than a scalable technology venture. While the business has demonstrated longevity (launching in 2015), the submission relies on hyperbolic claims (reach: 'everyone', traction: 'most people') and ambiguous financial metrics ('500000 marketcap') that likely represent cumulative small-business revenue. There is no evidence of technological innovation or the significant user base required to score highly against the HackerNoon calibration (333).
