Proof of Usefulness Score
You're In Business

Coastr is a legitimate, verified B2B SaaS company based in the UK, offering car rental management software with IoT and AI integration. External verification confirms the company has raised approximately $2M-$5M in funding and employs around 45 people (contradicting the 125 claimed). However, the project submission itself was of extremely poor quality, containing demonstrable falsehoods (claiming 'most people have used my product' and an audience of 'everyone') and ambiguous financial data ('marketcap: 17000000'). Consequently, while the company's real-world utility and verified traction are solid, the score is heavily penalized by the 'Quality Factor' multipliers due to the vague, exaggerated, and unsupported claims in the submission.
