Proof of Usefulness Score
Certified Problem Solver

Project verified as Line Financial PBC, a legitimate and well-funded ($125M+) fintech platform for gig workers with significant traction (>600k users). However, the submission itself is of extremely low quality, containing hyperbolic claims ('most people have used my product') and lacking specific data. The score reflects the high verifiable value and scale of the actual company, heavily penalized by the poor evidence and lack of effort in the submission.
