Proof of Usefulness Score
Industry Mainstay

Catawiki is a verified, established 'unicorn' marketplace with significant real-world utility and traction (hundreds of millions in GMV, 750+ employees). However, the submission quality is critically low, featuring hyperbolic claims ('most people have used my product'), incorrect data entry (listing categories as technologies), and missing financial specifics. The score reflects the massive actual scale of the business, heavily penalized by low Quality Factors due to the lack of effort and precision in the provided input.
