Certified Problem Solver

Zzish (Quizalize) is a well-established EdTech company with verified revenue (~$2M/year), significant funding (~$6M+), and global reach (millions of users). However, the submission quality is extremely poor, featuring unsupported exaggerations ('most people have used my product', 'everyone') and lacking verifiable data. The score reflects the strong underlying business reality, heavily penalized by the lack of evidence provided in the submission and the laziness of the response. The project is comparable in scale to the calibration baseline (HackerNoon) but scores slightly lower due to the quality of the application.
