Proof of Usefulness Score
You're In Business

The project represents a verified operating business, GrindStone Capital Services Ltd., which provides investor awareness and stock promotion services. However, the submission contains significant falsehoods, such as claiming the audience is 'everyone' and that 'most people have used' the product. While the business is functional with defined pricing and services ($12.5k/mo packages), the 'aggressive' marketing tactics described (mass social media posting) and the deceptive nature of the submission (Team size discrepancy: 30 vs 10 on site) result in a low score. The technology appears to be standard digital marketing labeled as AI.
