Proof of Usefulness Score
Gaining Momentum

Persium is a legitimate UK-based ClimateTech startup (participating in Santander X and Breathable Cities accelerators) focused on digital twins for air quality. However, the submission itself contains significant inaccuracies and 'hallucinations' (claiming 'most people' have used the product and an audience of 'everyone'), which severely impacted the Traction and Reach scores. While the underlying technology and problem-solution fit are promising, the submission quality was exceptionally low.
