Proof of Usefulness Score
Category Standard

Perlego is a verified, high-growth EdTech scale-up often cited as the 'Spotify for Textbooks'. External verification confirms significant traction with over $94M in total funding, ~$11M+ annual revenue, and a library exceeding 1 million titles (far higher than the 200k claimed in the submission). While the project itself has exceptional real-world utility and market fit, the submission appears to be low-effort or from a non-founder (using a likely student/employee ID email and vague claims like 'everyone'), which negatively impacts the response quality score. The final score reflects the company's established success and strong value proposition, adjusted for the quality of the specific entry.
