Proof of Usefulness Score
Gaining Momentum

The project 'Cello' (cello.so) is a verified, venture-backed B2B SaaS platform for user-led growth, having raised over $5M from reputable investors like HV Capital and Founders Fund. However, the submission data contains significant inaccuracies (claiming a 1967 launch, 1,000+ employees, and 'Consumer housewares' industry), likely conflating the software startup with 'Cello World', a plastics manufacturer. While the actual product demonstrates high utility, strong market timing in the PLG sector, and verified traction (customers include Typeform and Personio), the score is penalized by the low quality and factual errors of the submission response.
