Category Standard

Wallapop is a dominant, 'unicorn' status marketplace in Spain and Italy with verifiable massive scale (>15M users, >€70M revenue). While the project submission text itself was low-effort (vague claims, incorrect metric labels), the underlying reality of the project scores exceptionally high on Utility, Reach, and Traction. The score reflects a top-tier established technology brand, penalized slightly for the poor quality of the submission description.
