Proof of Usefulness Score

Certified Problem Solver

Diduenjoy is a verified, established French B2B SaaS (founded 2014) with ~30 employees and profitability, operating in the customer feedback (NPS) space. While the project itself has high real-world utility and verified traction (ranking ~168th in its sector), the submission quality was extremely poor (vague claims, missing financial data). The score reflects the strong underlying business fundamentals discovered via external verification, heavily penalized by the low quality of the provided evidence.
