Risk Mirror (also known as PII Firewall Edge) addresses a critical and growing problem: protecting sensitive data (PII) from leaking into AI models. The solution's 'stateless' and deterministic (regex/checksum) approach is technically sound, offering low latency (49ms) and privacy compliance without introducing new AI risks. While the project is in the very early stages of growth (<500 MAU), the existence of 28 paying subscribers validates specific market demand and willingness to pay. The project fits the 'Minimal traction' category (0-100) but scores highly within it due to verifiable revenue and strong problem-solution fit.
