Certified Problem Solver

Hawaiian Cool Water is a verified, established business group (including AAA Best Water and Puro Rabjohn) providing water filtration infrastructure in Hawaii and Los Angeles. While the project submission was extremely poor (lazy data entry, hyperbolic claims), independent analysis confirms significant real-world traction, over a decade of operations, and strategic acquisitions. The high score reflects the legitimate scale and utility of the physical business, heavily penalized by the lack of effort in the submission data.
