Proof of Usefulness Score
Gaining Momentum

Blue Sparrow Apps is a legitimate, Bristol-based development agency established in 2015 with a verifiable portfolio (e.g., FanHub, PoliceBox). However, the project submission is of poor quality, containing hyperbolic claims ('most people have used my product', 'audience reach: everyone') and lacking financial or user metrics. While the underlying business has proven technical capability and client traction (FanHub raised $3M), the evaluation is penalized for the unprofessional submission and lack of direct product data.
