What RexSoft does
RexSoft Co., Ltd. is a South Korea-based health data analytics and AI health management company founded in June 2018 by Professor Won Sung-ho of Seoul National University Graduate School of Public Health. The company operates two complementary product lines. The B2B Rex Solutions suite includes Rex-Pro, Korea's first GUI-based Microsoft Excel plug-in for semi-automated statistical analysis (19 analysis menus, 16 graphics menus, and ~90 submenus); Rex-QC, a clinical data quality-control and standardization solution; and Rex-LIMS, a laboratory information management system. These products are sold on annual license subscriptions to healthcare institutions, government agencies, and university research institutes, with approximately 10 domestic institutions currently licensed.
The B2B2C/B2C Miriwell suite is an AI-driven personal health management service that uses the company's proprietary analysis engine to predict disease risk, life expectancy, and health age from health examination and Personal Health Records data, supported by models trained on health, genomic, and microbiome data from approximately 5 million Korean individuals. The Miriwell app (available on Google Play and iOS App Store) and the Miriwell-Biz corporate wellness product extend the platform to consumers and enterprise wellness programs, reaching 650,000 users in 2023, up from 300,000 in 2022.
The company monetizes through annual B2B software licenses, consumer and corporate SaaS subscriptions, analytics consulting services, and government contracts. Of 24 total employees, 17 work in data analysis and development, including 9 with master's or doctoral degrees. In February 2023 Daesang WellLife invested 2 billion KRW and an additional 2.8 billion KRW in August 2023, securing a 50.2% controlling stake; full acquisition was completed in August 2024, making RexSoft Daesang WellLife's first subsidiary for its healthcare platform business. RexSoft is pursuing international expansion into China, Indonesia, and Vietnam through Daesang WellLife, and is extending into AI-based medical image processing and multi-omics diagnostics via its 2025 MOU with Inje University Biomedical Center.
