Category Standard

Crystal (crystalknows.com) is a verified, established market leader in personality AI (DISC profiling) with estimated annual revenue of ~$5.5M and significant funding (~$7M). While the project itself demonstrates high real-world utility and traction, the submission contained factual errors (e.g., Launch Date 1984) and vague claims ('everyone', 'most people'), which severely penalized the Response Quality and Evidence of Traction scores compared to the project's actual performance metrics.
