HiStranger, Inc. is a deep-tech company building next-generation Emotion AI data infrastructure through 'Insight Flow', a multimodal Emotion AI analytics solution that quantifies human emotion. Our proprietary technology fuses four biosignals — brainwave (EEG), pulse (PPG), facial expression (FER), and gaze — achieving 94.18% emotion-recognition accuracy certified by KTCC. Combined with our capability to collect, process, and label multimodal emotion data, we are driving the commercialization of Emotion AI. Today, we serve media and content companies at home and abroad across film, OTT, gaming, and advertising, and are expanding into new industries on the strength of 10,000+ multimodal emotion datasets accumulated in the industry where human emotion is expressed most richly. Emotion AI is a core foundational technology applicable across the entire Physical AI industry. ▲Manufacturing & Smart Factory — preventing safety incidents and reducing human error through real-time analysis of worker fatigue, stress, and concentration; ▲Healthcare — supporting state assessment of critically ill patients through objective measurement of patient anxiety and pain; ▲Mobility — enabling next-generation in-cabin safety systems through emotion and state analysis of drivers and passengers; ▲Aerospace — enhancing mission performance and stability in extreme environments through psychological monitoring of astronauts; ▲Robotics — realizing human-centered AI services through human-robot interaction (HRI) that understands and responds to human emotion. In an era where humans and AI work together, HiStranger provides the 'Emotion Layer' that AI needs to understand people — building the core infrastructure of Physical AI. Our technology has been validated on the global stage — Korea's first-ever selection to Berlinale EFM Startups (2025) and finalist at both South Summit Madrid and IVS LaunchPad Kyoto (2026, the only Korean company at each) — and we hold five patents (one granted, including PCT and USPTO filings), securing core competitiveness in Emotion AI technology.
