Proof of Usefulness Score
Industry Mainstay

RosieApp is a legitimate and successful grocery e-commerce platform (acquired by Instacart in 2022) with verifiable real-world utility and traction in the independent grocer market. However, the submission itself is of extremely low quality, featuring unprofessional details ('SilentBlade'), hyperbolic claims ('most people have used my product'), and a lack of specific metrics. The score reflects the strong underlying reality of the business (high utility, successful exit) significantly penalized by the poor quality of evidence and response provided in this specific submission.
