Proof of Usefulness Score
Unicorn Utility

Tutteo (Flat.io) is a highly successful, verified SaaS platform with significant market penetration (5M+ users, 14k+ schools). The product solves a clear problem ('Google Docs for Music') with robust technical execution. However, the submission itself was low-quality, featuring hyperbolic claims ('most people have used my product') and missing financial data. The high score reflects the verifiable success and utility of the platform, heavily penalized in the Response Quality metric due to the submitter's lack of effort.
