The submission references a real but dormant/deadpooled company ('DefenCall', est. ~2010) that specialized in campus safety apps. However, the submission contains hyperbolic and demonstrably false claims (e.g., 'most people have used my product', audience reach 'everyone') which contradict market reality. The company appears to have ceased significant operations or been acquired/shelved years ago. The lack of current data, combined with low-quality responses and zero verifiable active traction in 2026, results in a near-zero score.
