AMCG

What AMCG does

AMCG Co., Ltd. is a South Korea-based medical device company founded in 2021 that develops and commercializes magnetocardiography (MCG) diagnostic systems for non-invasive cardiac disease detection. The company was established after receiving SQUID (Superconducting Quantum Interference Device) sensor and MCG system technology from the Korea Research Institute of Standards and Science (KRISS), where the underlying platform was developed over more than 30 years. Its flagship product, the MCG-S, is the world's first 96-channel SQUID-based MCG system that measures ultra-fine cardiac magnetic signals (on the order of 10^-11 Tesla) and is designed to replace multiple step-by-step cardiac tests — including ECG, echocardiography, cardiac CT, SPECT, and coronary angiography — with a single non-invasive 2–3 minute scan, reporting sensitivity of 90.5% and specificity of 92.3% for ischemic heart disease. MCG-S received Korean MFDS item approval in June 2022 and US FDA 510(k) clearance in April 2024, and is supported by a proprietary in-house helium reliquification system that materially reduces operating cost.

The company monetizes through direct hospital sales of the MCG-S capital equipment, with systems currently installed at two South Korean hospitals (Gachon University Gil Hospital and Eunpyeong St. Mary's Hospital) that are also running multi-center post-marketing Phase 4 clinical trials enrolling approximately 600 patients. A complementary revenue stream derives from government R&D grants (Scale-up TIPS plus a Ministry of Trade, Industry and Energy program, totaling approximately 3.7 billion KRW). Forward-looking revenue mechanics include national health insurance (HIRA) coverage targeted for 2026, which would convert per-test billing into a recurring reimbursement stream, and the planned 2026 launch of a lightweight MCG-F seated-type device aimed at the health check-up center segment. AMCG went public on KONEX in December 2024 (with a stated KOSDAQ transfer goal within two years), is led by CEO Seo Yong-sung and CPO Chang-Won Kim, and is pursuing geographic expansion into the United States, China, and other Asian markets while building strategic supply-chain partnerships — most notably with Sumitomo Heavy Industries on cryogenic refrigeration.

Revenue model

1. Medical Device Sales (MCG-S): Sale of MCG-S magnetocardiography diagnostic systems to hospitals. The system is currently installed in two hospitals in South Korea and has received FDA 510(k) clearance for the US market.
2. Health Insurance / National Health Coverage: AMCG plans to apply for new medical technology assessment in 2025 and health insurance coverage (HIRA) in 2026, which would enable hospitals to bill for MCG scan tests under national health insurance, creating a reimbursement-based revenue stream.
3. MCG-F Health Check-up Market: Planned launch of the lightweight MCG-F model in health check-up centers, targeting the rapidly growing health screening market in South Korea and internationally.
4. Government R&D Grants: Government contributions through Scale-up TIPS (R&D) projects and Materials and Components Technology Development Project. Total government funding secured is approximately 3.7 billion won across multiple programs.

Core offering

AMCG develops and sells the MCG-S magnetocardiography diagnostic system, a non-invasive cardiac imaging device using 96-channel SQUID quantum sensors to detect magnetic signals from the heart. The system provides all-in-one heart disease diagnosis with 90.5% sensitivity and 92.3% specificity for ischemic heart disease in 2-3 minutes, without radiation, contrast agents, or invasive procedures. A lighter MCG-F model is planned for the health check-up market in 2026.

Product overview

AMCG provides an all-in-one cardiac diagnostic solution through its MCG-S system and developing MCG-F model. MCG-S is the primary FDA-cleared product featuring a 96-channel SQUID sensor system that replaces multiple step-by-step tests (electrocardiogram, echocardiography, SPECT, CT) with a single non-invasive scan. The follow-up MCG-F model targets health check-up centers with a lightweight design. Both products use AI-based noise elimination and diagnostic algorithms, integrated with helium reliquefaction technology for SQUID sensor cooling at -270°C.

• Sumitomo Heavy IndustriescoreStrategic or Co-development Partner · 17 June 2025AMCG and Sumitomo Heavy Industries (Japan) signed a Memorandum of Agreement on June 17, 2025 to strengthen collaboration on helium reliquification/refrigeration technology for MCG systems. The agreement aims to collaborate on refrigeration unit modification and development, support maintenance, and strengthen market competitiveness. Prior to signing, both companies visited Eunpyeong St. Mary's Hospital to observe MCG-S operations and discuss future refrigeration modification improvements.
• Korea Research Institute of Standards and Science (KRISS)coreTechnology or IntegrationAMCG received SQUID (Superconducting Quantum Interference Device) technology and Magnetocardiography (MCG) system technology from KRISS for commercialization. KRISS developed the technology over more than 30 years under Dr. Lee Yong-ho's team. KRISS Director Dr. Park Hyun-min attended the clinical trial kick-off meeting. AMCG continues collaboration with KRISS through technology transfer and research partnerships.
