Proof of Usefulness Score
Category Standard

Sandbox VR is a verified, high-growth location-based entertainment company with significant backing ($37M+ disclosed, likely higher) and a global footprint (40+ locations). The submission correctly identifies the entity but provides low-effort responses for specific fields ('most people have used my product', 'marketcap: null'). Despite the poor submission quality, the project's real-world evidence—proprietary full-body VR tech, large team size (500+), and verified market leadership—drives a high PoU score. The score is penalized slightly for the hyperbolic traction claims in the input fields.
