Industry Mainstay

CashBook is a verified, venture-backed (Y Combinator W21) fintech startup in India with over 1 million downloads and significant real-world utility for SMBs. However, the submission quality was extremely poor, featuring vague technical descriptions ('Internet'), hyperbolic traction claims ('most people'), and a lack of supporting evidence. The high score is derived from external verification of the project's legitimacy and scale, while the submission's low quality significantly reduced the potential maximum score.
