Proof of Usefulness Score
Gaining Momentum

eFour is a legitimate B2B product engineering and embedded systems consultancy (subsidiary of Excellent Webworld) operating since roughly 2011. However, the project submission is of critically low quality, containing demonstrably false claims (e.g., 'most people have used my product' and an audience of 'everyone') and confusing metrics ($500k 'market cap' for a 30-person service firm). While the business has verifiable utility in the industrial/IoT space, the disconnect between the actual B2B nature of the company and the exaggerated consumer-facing claims in the submission significantly lowers the confidence and score.
