Proof of Usefulness Score
Category Standard

Poshmark is a highly established social commerce platform with verifiable massive scale (80M+ users) and a proven exit (acquired by Naver for ~$1.2B). The project demonstrates exceptional Real-World Utility and Traction. However, the submission itself was of extremely low quality, with vague claims ('most people have used my product') and empty fields, which prevented a higher score. The evaluation relies heavily on external verification of the brand's known status rather than the data provided.
