E-RAY Corp.

E-RAY Corp. appears to be a legitimate South Korean B2B manufacturer of industrial X-ray components (established 2020) with a team of 30, addressing a high-utility niche (semiconductors/batteries). However, the submission quality is critically low, containing hyperbolic and inaccurate claims (e.g., audience is 'everyone', traction is 'most people have used my product'). While the underlying business has potential and aligns with market timing, the complete lack of verifiable evidence and the confusing metrics (revenue listed as 'marketcap') result in a low Proof of Usefulness score.
