Proof of Usefulness Score
Category Standard

Elsa Corp (ELSA Speak) is a highly established, venture-backed EdTech company with significant verifiable traction (50M+ users, Google Gradient Ventures investment). The project demonstrates exceptional Real-World Utility and Audience Reach. However, the submission quality itself was poor; the user 'DeepShade' provided flippant responses in the traction fields ('most people have used my product') and incorrect tags ('Real Estate'), which slightly lowered the confidence/quality factors. Despite the lazy submission, the underlying entity is a high-value, market-validated product.
