Proof of Usefulness Score
Certified Problem Solver

C3 LLC is a verified, established manufacturer (est. 2009) of shopping cart retrieval safety devices used by major chains like Lowe's and Kroger. While the project has high real-world utility and strong verifiable traction (national retail deployments), the submission itself was of poor quality—containing vague claims ('most people have used my product'), malformed financial data ('marketcap: 2500000'), and a lack of direct evidence. The score reflects the strong underlying business fundamentals and 'Standard Practice' industry status, penalized heavily for the low-effort submission and unsupported claims.
