## About

Based in Seoul, South Korea, and founded in 2026, StealCut Inc., doing business as StealCut develops AI security solutions focused on deepfake prevention and detection. The company's technology originated from research on adversarial AI protection for facial images that began in August 2024. The company subsequently built a research team composed of Seoul National University alumni, filed multiple domestic patents, established research partnerships with Korea University and Seoul National University College of Engineering, and conducted proof-of-concept projects with academic institutions and media organizations. In March 2026, StealCut raised a seed investment from Mashup Ventures. The company focuses on developing AI-based deepfake prevention and detection technologies. Its flagship solution, StealCut Protect, applies adversarial perturbation techniques to portrait images, making them resistant to deepfake generation models while remaining visually unchanged to human users. The company also provides deepfake detection capabilities and API-based integration services that enable organizations to incorporate image protection into existing platforms and workflows. The company's revenue is generated by licensing and commercializing its AI security solutions, including deepfake prevention and detection products, API integration services, and enterprise partnerships that enhance image security, trust, and regulatory compliance for digital platforms. The company will use the funding to further develop and commercialize its deepfake prevention and detection technologies, expand research collaborations, strengthen its intellectual property portfolio, and accelerate market adoption of its AI security solutions. The funding is also expected to support product development and business expansion following successful proof-of-concept projects and industry recognition.
