Certified Problem Solver

MAYU Water creates verified hardware (the 'Swirl' carafe) with proven aesthetics and aeration benefits, backed by successful Kickstarter campaigns ($500k+) and active sales. However, the project relies heavily on 'structured water' pseudoscientific marketing which reduces its utility score. The submission quality was extremely poor, containing false claims ('most people have used my product') and lazy data, which significantly penalized the Traction and Reach metrics despite the existence of a real, revenue-generating business (~$1M-$3M est. annual revenue).
