Lumiode, Inc.
Lumiode is a New York-based fabless semiconductor startup building truly-monolithic micro-LED microdisplays. By depositing low-temperature polycrystalline silicon (LTPS) thin-film-transistor backplanes directly onto LED epiwafers - skipping the wafer-bonding step used by most rivals - Lumiode produces ultra-high-brightness, low-power, small-form-factor displays aimed at augmented reality, head-up displays and projection. Spun out of Columbia University in 2012 and led by co-founder and acting CEO Ioannis (John) Kymissis, the company raised roughly $16 million in venture funding before agreeing in December 2025 to be acquired by Taiwan's PlayNitride.
DigiLens Inc.
DigiLens is a Silicon Valley optics company that designs, manufactures, and licenses holographic waveguide displays - the transparent, printed lenses that let augmented reality smartglasses overlay digital information onto the real world. Founded in 2003 as SBG Labs around a switchable Bragg grating technology, the company pairs its proprietary CrystalClear photopolymer with an inkjet-printing and holographic contact-copy process it argues can scale AR optics to consumer price points. Alongside licensing its optics to manufacturers, DigiLens builds ARGO, a standalone AR/XR smartglasses platform aimed at enterprise and industrial workers, and counts Samsung, Sony, Continental, and Niantic among its investors.
