Proof of Usefulness Score
Category Standard

Blacklane is a verified, major global player in the luxury chauffeur market with estimated annual revenue exceeding $280M and over 400 employees, far surpassing the 'comparable scale' baseline. However, the project submission itself is of extremely low quality, featuring hyperbolic claims ('most people have used my product'), invalid data fields ('all time marketcap: null'), and a suspicious email format (numeric ID vs. standard corporate format). While the real-world entity is a 'unicorn' status company (Series G, >$2B valuation), the score is penalized due to the lack of professional detail and evidence provided in the submission form itself.
