Proof of Usefulness Score
Category Standard

Taxfix is a verified European fintech unicorn with significant real-world utility and massive market reach ($1B+ valuation, millions of users). However, the submission itself is low-quality, relying on copy-pasted marketing text and hyperbolic claims ('most people have used my product') rather than precise data. While the project's intrinsic value is high (unicorn status), the evaluation score is tempered by the laziness of the specific submission response.
