The submission references Zettle, a highly successful fintech company acquired by PayPal for $2.2B. However, the submission itself contains significant red flags: an invalid email format ('@zettle.com/gb'), contradictory dates (launching in 1998 vs. founded 2010), and extremely vague, low-effort claims ('most people have used my product'). While the subject matter represents high real-world utility and traction, the specific submission fails to provide verifiable evidence or credible ownership, resulting in a heavily penalized score due to low quality factors.
