Proof of Usefulness Score
Unicorn Utility

Buzzvil is a verified, high-growth Series C AdTech company based in Seoul with estimated annual revenue exceeding $70M and over 90M cumulative users (significantly higher than the outdated 12M figure provided in the submission). While the project itself demonstrates exceptional traction, market dominance, and proven utility through its lockscreen advertising SDKs and acquisitions (Slidejoy), the submission quality is critically low, featuring lazy placeholder text and outdated statistics. The score reflects the massive real-world success of the business, adjusted slightly downward for the poor quality of the application data.
