Proof of Usefulness Score
Certified Problem Solver

Mashroom is a legitimate, venture-backed UK PropTech company (raised ~£7M) that recently sold its rent collection portfolio to pivot towards lead generation. However, the submission is of very low quality (user 'BlazeClaw', hyperbolic claims like 'most people', and 'everyone'). The score reflects the verifiable real-world value and traction of the company, heavily penalized by the poor accuracy and professionalism of the submission input.
