Proof of Usefulness Score
You're In Business

Nubart is a legitimate, established business (est. 2013) serving ~200 cultural institutions globally with valid B2B traction. However, the submission quality is critically poor, featuring empty financial data, hyperbolic claims ('most people have used my product'), and conflicting project names ('DeepRider'). While the underlying business has real-world utility and verified longevity, the submission fails to provide adequate proof, resulting in a significantly penalized score.
