Proof of Usefulness Score
Category Standard

Brille24 is a verified, market-leading online optical retailer in Germany (est. 2007) with high real-world utility and massive verifiable traction. Although the submission contained hyperbolic claims (e.g., 'most people have used my product') and lacked specific data, the external reality of the business—including its acquisition by EssilorLuxottica—justifies a high score. The project is fully mature with significant reach, far exceeding the calibration baseline, though the score is dampened by the low quality of the provided responses.
