Proof of Usefulness Score
Industry Mainstay

Project verified as 'KabuK Style Inc.' (HafH), a legitimate Series B Japanese travel fintech with ~$30M funding and ~127k users. However, the submission quality is critically low, containing hyperbolic false claims ('everyone', 'most people') and missing data. The score reflects the high real-world value and traction of the underlying business, significantly penalized for the poor quality and lack of evidence in the submission itself.
