Proof of Usefulness Score
Category Standard

HyperionDev (CoGrammar) is a verified, mature EdTech scale-up with significant backing (Series A, >$30M raised) and a large workforce (~362 employees), placing it well above the calibration baseline of HackerNoon. However, the submission itself was of extremely poor quality, containing hyperbolic and false claims ('most people have used my product', 'audienceReach: everyone'). The score reflects the verifiable real-world success of the business entity while penalizing the lazy submission and mixed user reviews regarding course quality.
