LetinAR secures $18m ahead of South Korean IPO

South Korean optical module startup LetinAR has raised US$18.5 million from Korea Development Bank, Lotte Ventures, and other investors ahead of a planned 2027 IPO in South Korea, as suppliers prepare for higher demand for AI smart glasses.

LetinAR, founded in 2016 by Jaehyeok Kim and Jeonghun Ha, makes lens modules that project images into a user’s field of vision and said the round brings its total funding to US$41.7 million and will help scale production.

The company said its modules are shipping to customers including Japan’s NTT QONOQ Devices and Dynabook, while Swiss AR helmet maker Aegis Rider plans to launch a product using LetinAR’s module in the EU and Switzerland in 2026.

Omdia estimated global AI glasses shipments reached 8.7 million units in 2025 and will pass 15 million in 2026.

🧠 Food for thought

Implications, context, and why it matters.

LetinAR’s funding rests on a defined optical approach and public customer backing

  • LetinAR says PinTILT is a hybrid optical system built for easier large-scale manufacturing through plastic injection molding, a common production method 1.
  • At CES 2024, LetinAR said FrontiAR Pro improved brightness uniformity by about three times versus its earlier PinMR (Pin Mirror) systems, tackling a persistent AR optics issue 2.
  • LetinAR has also presented products from Jorjin, which makes the J8L Glasses, and Nimo Planet, whose Nimo One glasses target workplace use on large virtual screens 2.
  • Those ties suggest wider commercial demand, and Nimo Planet credited LetinAR with enabling an “ultra-comfort” design 2.

A supplier focused on parts hints at a more mature AR market

  • LetinAR works as a “picks and shovels” supplier, selling optical modules and evaluation kits for testing instead of relying on a single consumer device 3.
  • Its push for lighter, lower-power modules fits LetinAR’s stated aim to make augmented reality glasses comfortable for all-day wear 1.
  • Customers such as Jorjin and Nimo Planet suggest AR is branching into distinct business uses rather than settling around one mass-market role 2.
  • Progress at the component level can lower barriers for smaller device makers, opening the door to more specialized products beyond those from large tech companies.
