Proof of Usefulness Score
Industry Mainstay

Yellow Card is a legitimate, major Pan-African fintech company (Series C, ~$90M funding, ~$255M valuation) with over 1 million verifiable users. While the project submission itself was extremely low-quality (lacking data, hyperbolic claims like 'most people', and missing technical details), external verification confirms high real-world utility, significant market traction, and widespread adoption across 16+ African countries. The score reflects the company's substantial scale and utility (boosting the base metrics) but is heavily penalized by low Quality Factors due to the poor evidence provided in the submission.
