Proof of Usefulness Score
Category Standard

Nulab is a well-established, publicly traded company (TYO: 5033) with a robust suite of collaboration tools (Backlog, Cacoo, Typetalk) and millions of global users, far exceeding the baseline for this evaluation. However, the submission itself was of extremely low quality, utilizing a generic email address, providing no concrete metrics (revenue, active users), and relying on hyperbolic claims ('most people have used my product'). Consequently, while the base scores for Utility, Reach, and Traction are high due to verifiable external reality, the Quality Factors were penalized significantly to reflect the lack of direct evidence provided in the application.
