Proof of Usefulness Score
Certified Problem Solver

Courier is a high-utility, Series B funded notification infrastructure platform (Y Combinator S19, backed by GV) with significant verifiable external traction (~$57M funding, enterprise adoption). However, the specific project submission provided was of extremely low quality, containing vague claims ('most people have used my product'), incorrect categorization ('Delivery' vs 'SaaS'), and missing data. The score reflects the strong real-world value and market position of the actual Courier.com platform, heavily penalized by the lack of direct evidence and effort in the submission itself.
