Proof of Usefulness Score
Gaining Momentum

Wattsun is a verified Dutch scale-up (founded 2016) offering high-utility portable battery systems to replace diesel generators, a strong problem-solution fit in the climatetech sector. However, the submission itself is of very poor quality, utilizing hyperbolic claims ('most people have used my product') and vague data ('audience reach: everyone') rather than concrete metrics. While the project's real-world traction is respectable (11-50 employees, established B2B market), the PoU score is significantly dampened by the lack of verifiable evidence provided in the input and the unprofessional response quality.
