Proof of Usefulness Score
Unicorn Utility

Short Story is a highly successful, verified Y Combinator (S19) company with estimated annual revenue of ~$40M and a team of 140-160 employees. While the submission itself contained lazy and inaccurate filler text (e.g., claiming 'everyone' as the audience and 'most people' as traction), external verification confirms it is the market leader in petite personal styling. The project demonstrates exceptional real-world utility and traction, far exceeding the calibration baseline, though the score is slightly dampened by the poor quality of the input data provided.
