Proof of Usefulness Score
You're In Business

Fiberplane is a legitimate, venture-backed developer tool startup (approx. $8.8M seed funding) known for creating the HONC stack and collaborative DevOps notebooks. However, the submission itself is of extremely low quality, containing factual errors (launch date 1987), hyperbolic claims ('most people have used my product'), and inaccurate team size data (claimed 125 vs actual ~20-50). The score reflects the high real-world utility and technical innovation of the actual product, heavily penalized by the lack of credible evidence provided in the submission.
