Proof of Usefulness Score
Category Standard

Roto-Rooter is a massive, verified legacy business (est. 1935) with undeniable real-world utility and market dominance (~$2B+ annual revenue context via parent Chemed). However, the project submission itself is of extremely low quality, lacking any technical detail, specific innovation claims, or effort. While the entity scores exceptionally high on Utility, Reach, and Traction due to its verifiable real-world status, it scores very low on Technical Innovation and Response Quality. The final score reflects the sheer scale and necessity of the business, penalized slightly for the lack of a coherent technology project presentation.
