About SDT

SDT Inc., formerly known as Sigma Delta Technologies, was established in 2017 by founder and CEO Jiwon Yune. Mr. Yune's fascination with natural sciences led him to delve into quantum physics at MIT, where he earned bachelor's and master's degrees in Physics and Electrical Engineering. His research across various quantum computing technologies provided him with a comprehensive understanding of the quantum ecosystem, which he later applied at the Korea Institute of Science and Technology (KIST). This background spurred him to found SDT with the mission of integrating quantum technology into industrial and everyday applications.

Headquartered in Seoul, South Korea, the company operates at the intersection of quantum technology and digital transformation. SDT is focused on commercializing quantum solutions across four main areas: quantum computing, quantum cloud, quantum communication, and quantum sensing. The business develops Internet of Things (IoT) optimized modules, system-on-modules, development tools, and accessories. These products are designed to lower the entry barrier for companies to connect devices to cloud networks and operating systems, providing secure hardware for various applications.

The company's offerings serve a diverse client base in sectors such as smart manufacturing, smart retail, and smart mobility. For instance, SDT developed an AI platform based on Google Coral for edge devices and has entered the smart manhole and smart building management industries. Their business model appears to be venture capital-backed, with several funding rounds, including a Later Stage VC round of $14.3M in December 2024. SDT's product portfolio includes the 'SDT Smart Hub', an intelligent sensor system, and the SDT Cloud, a platform for unified device and data management at the industrial edge. This cloud platform enables real-time monitoring, machine learning, and control of industrial assets, supporting a resilient MLOps cycle from edge to cloud. A significant milestone was the development of South Korea's first full-stack quantum computer, showcasing the company's progress in the quantum field.
