In early 2025, our founder, Oleksandr Chibisov, faced a recurring problem while repairing appliances: technicians often lacked quick access to accurate diagnostic information, especially in high-stakes cases like gas leaks, fire hazards, or refrigerant issues. While working in Texas and collaborating with service companies across the U.S., Oleksandr realized that many failures could be prevented if technicians had a single, intelligent knowledge base built on real repair cases — not just theory. This insight marked the birth of Sayfee — an AI-powered diagnostic assistant designed to make homes safer and technicians more effective. From day one, the mission was clear: combine real-world expertise with artificial intelligence to deliver instant, practical, and safe repair guidance.
