## Summary
Guy Rosenhoiz is an AI Platforms Builder, payments expert, and serial entrepreneur with 20+ years taking deep-tech ventures from concept to global scale. His work sits at the intersection of artificial intelligence, regulated financial infrastructure and platform economics: he does not add AI as a feature - he designs systems where models are the core execution layer. Across his ventures this shows up in different forms: Noxify (deep-tech AI-native NOC and SOC AI security platform), SLM.ZONE (LLM/SLM training and deployment), Revenues Master (AI financial brain), and Merlin (AI-native enterprise operating system). This AI-native focus is built on a long foundation as a forerunner in next-generation payment technologies, including leading six payment companies, forging partnerships with Mastercard, Visa, Apple Pay and others, and building card issuing, embedded-finance and loyalty-to-payment rails. He holds 18 registered patents spanning fintech and AI.
