Founded in 2000 and headquartered in Daejeon, K3I is an XR (extended reality) content and solutions company that shifted from web-based system integration (SI) toward AR/VR/MR research and development starting in 2011.
It developed Korea's first augmented reality engine and authoring tool technology, and supplies XR middleware solutions built on this base across multiple industries.
As of 2023, XR immersive content construction reportedly accounted for 70.6% of revenue, the dominant share, with digital twin construction at 4.1% and traditional SI business at 25.3%.
Its main clients include local governments such as Busan, Daegu, Pohang, and Gyeongsan, as well as public institutions like science museums, and the company has been described as holding roughly an 85% project win rate that gives it a leading position in the B2G (public-sector) market.
More recently it has expanded its reference base into robotics, semiconductors, and aerospace, including a consortium win for XR content at a Jinju aerospace science museum.
Overseas, it opened the 'Immersify KL' immersive content exhibition hall in Kuala Lumpur, Malaysia in early 2025, with cumulative visitor numbers reportedly rising.
In April 2026 it opened the first 'Kinder Kino' location, a children's experiential content space built on its own 'MimFriends' intellectual property, broadening into IP-driven proprietary content business.
The company has also won the BolognaRagazzi CrossMedia Award, the first such win by an Asian entrant, for storybook content submitted to an international book fair.
Competitively, it faces small and mid-sized domestic immersive-content and SI vendors, while indirectly intersecting with the hardware and platform ecosystems of global technology majors such as Meta and Apple overseas.
