Proof of Usefulness Score
You're In Business

The project refers to Donkervoort, a legitimate and respected Dutch manufacturer of ultra-lightweight sports cars established in 1978. However, the submission itself is of extremely low quality, containing demonstrably false claims (e.g., audience reach is 'everyone', traction is 'most people', tech stack includes 'fashion'). While the underlying business has high real-world utility and technical innovation (carbon fiber chassis), the submission's lack of seriousness, inaccurate data, and spam-like characteristics ('ShadowRider', URL typos) severely penalize the final score. The evaluation reflects the existence of the reputable company but adjusts for the invalid submission data.
