Proof of Usefulness Score
You're In Business

Harbr is a legitimate London-based startup accelerator focusing on Health Tech (verified portfolio includes Doctaly, Sollis, Anathem). However, the submission quality was extremely poor, containing demonstrably false claims ('most people have used my product', 'audience reach: everyone') which heavily penalized the Evidence and Reach scores. While the project has high real-world utility and verified government partnerships (Healthcare UK), its B2B boutique nature and lack of verifiable scale (user count < 50k) place it in the 'Minimal Traction' score range relative to the calibration scale.
