Certified Problem Solver

The project 'StarWing' (URL: Chessable.com) is a verified, market-leading edtech platform acquired by Play Magnus Group for ~$80M+ and later by Chess.com. While the platform itself demonstrates exceptional real-world utility, massive reach (1M+ users), and proven revenue ($9.7M+ in 2021), the submission quality is critically low. The submission uses an incorrect project name, provides a generic email, and includes hyperbolic/false claims ('most people have used my product'). The score reflects the high value of the actual technology and business traction, significantly dampened by the lack of effort and professionalism in the submission data.
