Proof of Usefulness Score
You're In Business

Goodbill is a legitimate, high-potential startup (Y Combinator W22) addressing a critical issue in US healthcare billing. While the project itself demonstrates verified utility, raising over $5M in funding and securing coverage in Time Magazine (Best Inventions 2023), the submission quality is exceptionally poor. Claims like 'most people have used my product' are demonstrably false and degrade the credibility of the entry. The score reflects the strong underlying business fundamentals and market relevance, heavily penalized by the lack of effort and accuracy in the submission data.
