“We have completed the development of ‘RingDoc’, a digital healthcare solution for patients with musculoskeletal diseases, and are currently applying it in actual medical institutions. It has been officially adopted and utilized in several hospitals, and the resulting generation of actual revenue is evaluated as a significant achievement proving the effectiveness and commercial viability of the service.”
Itphy is a company founded in July 2022 by CEO Rhee Sung-min, a professor of orthopedic surgery at Kyung Hee University Medical Center. It aims to complement the limitations of the existing medical system through digital healthcare services specialized in musculoskeletal diseases.
CEO Rhee introduced the company, saying, “Itphy is a company that provides integrated digital healthcare supporting the entire process from disease prevention to post-occurrence progress monitoring, under the philosophy of ‘Connecting doctors and patients in a single Ring’.”
In 2025, Itphy received significant attention from the global market by being selected as an official participating company in CES, the world's largest IT exhibition. In addition, it is strengthening its foundation for overseas expansion by being successively selected for major government support projects such as the Ministry of Trade, Industry and Energy's 'Overseas Branch Support Project' and the Ministry of SMEs and Startups' 'Export Voucher Project'.
COO Lee Jae-jun stated, “We are accelerating the preparation of a foundation for entering the US market in 2026,” adding, “Discussions on cooperation with large hospitals in India have also begun in earnest, expanding the possibility of overseas expansion.”
RingDoc prevents musculoskeletal diseases based on personal health data before they occur. First, it measures the range of motion and evaluates joint function through AI motion analysis, and then predicts the current joint status based on data from thousands of patients. It is designed to enable preemptive responses at the stage before the occurrence or worsening of the disease based on collected health data such as analyzed joint status and individual underlying diseases.
“RingDoc is a hospital-based digital rehabilitation platform equipped with differentiated competitiveness that satisfies both actual clinical utility and user experience. It is a platform centered on clinical practicality developed under the leadership of orthopedic specialists. Practicing orthopedic specialists directly participated in the design and development, designing it so that patient conditions can be quickly and accurately identified even within the consulting room, and customized exercise prescriptions are possible. In particular, since the progress of functional recovery in post-operative or chronic pain patients can be tracked with objective reports, hospitals can secure not only treatment reliability but also patient management efficiency. Furthermore, partner hospitals are seeing effects in new patient inflow and improved revisit rates as the hospital is continuously exposed within the app through RingDoc. Moreover, it is establishing itself as a meaningful touchpoint in that it is being used as a new branding channel to convey the hospital's expertise and reliability beyond simple patient inflow.” (COO Lee Jae-jun)
CEO Rhee Sung-min said, “We have high user satisfaction and reliability.” He added, “According to a survey of actual users, 89% responded that they want to use RingDoc regularly, 84% are willing to recommend it to acquaintances, 89% said RingDoc is helpful for rehabilitation, and 95% found RingDoc clear and easy to use, proving high user satisfaction and intuitive usability.”
“Clinical Application on Hundreds of Patients and Presentation at International Conferences: RingDoc has been applied to actual clinical practice for hundreds of musculoskeletal patients to date, and as a result, significant effects have been confirmed in pain relief, recovery of joint range of motion, and functional improvement. These achievements were presented at international orthopedic conferences, being recognized for both expertise and objectivity.” (CEO Rhee Sung-min)
RingDoc is expanding its sales channels in a way that encompasses both medical sites and digital channels based on a hospital-centered B2H business model. Cooperation centered on university hospitals and specialized hospitals is also expanding. Through collaboration with major university hospitals and orthopedic specialty hospitals in the metropolitan area, it performs clinical research, pilot introductions, and joint data analysis, and is pursuing continuous service advancement reflecting medical staff feedback. Through this process, it is securing strong references based on actual use and inducing voluntary diffusion.
COO Lee Jae-jun stated, “We are also proceeding with a diffusion strategy utilizing direct touchpoints with medical staff.” He added, “We are actively utilizing orthopedic professional societies, medical conferences, and medical staff networks to spread adoption through direct contact with hospital officials. We selectively target institutions showing high interest in digital healthcare and proceed with 1:1 customized consultation and even post-adoption management.”
In addition, Itphy is actively participating in domestic and international exhibitions and academic conferences to promote RingDoc. CEO Rhee Sung-min said, “We are enhancing brand awareness in the global market and expanding touchpoints with overseas buyers through participation in major domestic and international academic conferences such as the Korean Orthopaedic Association and the Korean Shoulder and Elbow Society, presentation of clinical results, and participation in CES 2025.” RingDoc has also established a foundation for overseas expansion. “Selected for the MOTIE Overseas Branch Support Project and the MSS Export Voucher Project, we are securing touchpoints with medical institutions and distribution partners in major countries such as the US and India. To increase product understanding and reliability, we have opened a YouTube channel and are producing videos demonstrating RingDoc's main functions, patient reviews, and medical staff interviews. We are actively pursuing brand content promotion for medical experts and patients and expanding our follower base through SNS channels such as LinkedIn and Instagram.”
Itphy has mainly proceeded with technological development and clinical verification centered on government-supported R&D projects so far, and despite being in the early stages of commercialization, it is receiving attention from investors as actual revenue is being generated through subscriptions from several hospitals. It plans to attract Pre-A round investment in the second half of 2025.
Regarding future plans, CEO Rhee Sung-min said, “RingDoc aims to leap beyond establishing itself as a leading platform in the domestic musculoskeletal digital rehabilitation field to becoming a global digital healthcare company.” He added, “We are pursuing concrete strategies to advance as a ‘full-cycle integrated management platform’ from pre-surgery to post-surgery management.”
“We have completed the development of ‘RingDoc’, a digital healthcare solution for patients with musculoskeletal diseases, and are currently applying it in actual medical institutions. It has been officially adopted and utilized in several hospitals, and the resulting generation of actual revenue is evaluated as a significant achievement proving the effectiveness and commercial viability of the service.”
“We will establish the digital rehabilitation system within hospitals and upgrade the profit model. We are proceeding with licensing procedures so that hospitals and clinics can operate RingDoc as a non-reimbursable service or premium healthcare package. We are promoting service expansion centered on various departments such as orthopedics, rehabilitation medicine, and pain medicine. We are also developing low/medium frequency electrical stimulation hardware, preparing for expansion into a hybrid healthcare solution that supports pain relief and muscle regeneration. In addition, based on accumulated user data, we are developing an AI-based recovery prediction model that predicts patient pain, joint range, and recovery progress, as well as a digital twin-based personalized report function.”
COO Lee Jae-jun stated, “We will actively participate in future digital healthcare-related R&D projects (TIPS, Ministry of Health and Welfare, Ministry of Food and Drug Safety, etc.),” adding, “In the long term, we are preparing to enter the medical device market through digital therapeutic certification.”
Itphy was selected as a tenant company for the Kyung Hee University Campus Town project in recognition of its item. The Kyung Hee University Campus Town project is a project where the university and the region cooperate to support the economic revitalization of the area near the university.
