Proof of Usefulness Score
Unicorn Utility

Ookuma Diamond Device (ODD) is a highly significant deep-tech venture constructing the world's first diamond semiconductor manufacturing plant in Fukushima. With ~$50M in funding and critical applications in nuclear decommissioning, space (6G), and defense, the project scores exceptionally high on utility and innovation. However, the submission itself contained hallucinated claims (e.g., 'most people have used my product', 'audience: everyone') which severely impacted the Response Quality and Audience Reach metrics. The high score reflects the verifiable real-world value of the company despite the low-quality submission text.
