## About

Based in Seoul, South Korea, and founded in 2019, Raywatt Co., Ltd., trading under the name Raywatt Inc., operates as a medical device development company. In February 2025, Raywatt Co., Ltd. raised KRW 6.5 billion in series A funding from Industrial Bank of Korea, SBI Investment, L&S Venture Capital, ReInvestment, and OdaStone Investment. As of 2025, the company is led by its CEO, Ha Jin-yong.

Raywatt develops AI-enabled catheter-based imaging diagnostic devices. The company specializes in catheter-based Optical Coherence Tomography (OCT) imaging devices for intracoronary use. These devices are designed to provide high-speed, light-based imaging for plaque characterization and stent evaluation within coronary arteries. The company also utilizes OCT data as input for machine learning algorithms to predict Fractional Flow Reserve (FFR), a measure of blood flow in coronary arteries.

The company plans to utilize the funding raised in February 2025 to improve research, develop clinical applications, and expand globally by securing approvals from the United States Food and Drug Administration and other international regulators.
