Industry Mainstay

Vivaldi Technologies is a well-established, legitimate player in the browser market with significant verifiable traction (~3.5M active users, ~$10M+ estimated revenue). While the project itself is of high utility and scale (exceeding the calibration baseline of HackerNoon), the specific submission provided was of low quality, containing exaggerated claims (e.g., 'most people have used my product', team size of 350 vs actual ~60) and missing data. The final score reflects the strong external reality of the project, significantly penalized by the lack of direct evidence and accuracy in the submission.
