Proof of Usefulness Score
Gaining Momentum

Tumble (tumble.to) is a verifiable Seed-stage startup ($7M raised in 2022) providing IoT solutions for shared laundry rooms, with presence in ~300 locations. However, the project submission is of very low quality, containing false claims ('most people have used my product', 'audience reach: everyone') and lacking detail. While the technology and business model are valid and verified externally, the PoU score is penalized significantly by the hyperbolic claims and poor submission effort. The score reflects a 'Small but promising' venture, buoyed by external capital validation but dragged down by submission integrity.
