LetinAR, a South Korean startup specializing in optical modules for AI glasses, announced on May 19, 2026 that it has secured 27.8 billion won in a pre-IPO funding round. With this raise, the company’s total cumulative investment has surpassed 62.5 billion won. The round drew participation from 16 investors, including Korea Development Bank, Daesung Venture Investment, Kolon Investment, Evergreen Investment Partners, T3 Ventures, GSA Private Equity, GSA, Cape Investment & Securities, Hyundai Investment Partners, OpenWater Investment, NBH Capital, Bros Investment, Glommon Partners, Shinhan Capital, Union Investment Partners, and Lotte Ventures. Founded in 2016, LetinAR develops display-based optical modules — the core hardware components that power AI glasses.
The company has already begun mass production partnerships with international clients, including Japan’s NTT and laptop maker Dynabook, as well as Israeli AR headset manufacturer Lumus. LetinAR plans to use the proceeds to advance R&D on its optical modules and scale up global production capacity, with a focus on expanding its customer base in China, the United States, and Europe. The company is targeting a technology-exception IPO listing on the Korean stock exchange in 2027.
