Proof of Usefulness Score
Industry Mainstay

Lingo Live is a verified, established B2B coaching platform acquired by Preply, with estimated annual revenue of ~$15M and significant enterprise clients (Google, Slack, Eventbrite). Despite the high-value real-world status, the submission quality was extremely poor, containing false claims ('everyone' audience) and facetious evidence ('most people have used my product'). The final score reflects the strong underlying business fundamentals and market position, heavily penalized by the lack of credible submission data and the 'Quality Factor' reductions.
