Founded in 1999, SELVAS AI is Korea's first listed AI specialist, having built up human-computer interaction (HCI) source technologies including speech-to-text, text-to-speech, optical character recognition, handwriting recognition, and natural language processing.
In 2023 the company acquired a controlling stake in medical-device maker Mediana, shifting its business structure from a software-centric model to an AI-and-medical-device hybrid, and began consolidating Mediana's results from the following year.
As a result, the medical-device manufacturing and sales segment generated revenue of KRW 37.4 billion in the first half of 2026, up 25.9% from KRW 29.8 billion a year earlier, and its share of consolidated revenue rose from 54.7% to 62.4%.
Mediana's core products are patient monitoring devices (PMD) and automated external defibrillators (AED), with first-half PMD revenue of KRW 18.8 billion up 53% year over year on expanded North American and European exports.
Another subsidiary, SELVAS Healthcare, makes body-composition analyzers (AccuNiq), electronic blood-pressure monitors, and assistive devices for the visually impaired (BrailleSense series); body-composition analyzers now account for roughly 60% of its revenue, and an exclusive supply partnership with Australia's Evolt is expanding overseas sales.
The core AI solutions business spans automated medical-record speech recognition for hospitals, text-to-speech deployed on the RIDI e-book platform, and in-vehicle voice-recognition middleware built with partners including Amazon Alexa, Baidu, Cerence, and SoundHound for automakers, alongside public-sector projects such as an integrated operating-room control demonstration at a military hospital.
In voice AI, large IT firms such as Naver, Samsung Electronics, and Kakao are potential competitors, but for them this is a peripheral business, whereas it is a core focus for SELVAS AI.
In medical devices, the company competes against both large global device makers and domestic rivals, differentiating itself through an integrated monitoring platform strategy that combines hardware with AI software.
