Proof of Usefulness Score
Category Standard

FlixBus is a verified European unicorn with verifiable massive scale (5,500 employees, ~$3B valuation), dominating the intercity mobility market. While the real-world utility and traction are exceptional, the submission itself is of very low quality (vague claims, informal tone, lack of technical detail), which heavily penalized the Innovation and Response Quality scores. The score reflects a top-tier business entity hampered by a poor Proof of Usefulness application.
