Proof of Usefulness Score
Category Standard

BlaBlaCar is a well-established 'unicorn' in the mobility sector with verified massive scale (100M+ users, ~$2B valuation), placing it in the highest tier of real-world utility and traction. However, the submission itself was of low quality, featuring vague descriptions ('everyone') and generic tags, resulting in significant penalties to the Innovation and Response Quality metrics. Despite the poor entry effort, the undeniable market presence and verified metrics drive a high final score.
