Seyed Tabatabaei
Seyed A. Tabatabaei is the founder, chairman and CEO of mmTron, a Redwood City fabless semiconductor company building high-linearity millimeter-wave MMICs for 5G, 6G, SATCOM, instrumentation and defense. A PhD engineer who has worked in mmWave since 1986, he spent decades at M/A-COM, Hewlett Packard, and Endwave before starting the design house Teramics and then founding mmTron in 2020. In April 2026 the company closed a $45M Series A led by Maverick Silicon.
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.
VORAGO Technologies
VORAGO Technologies is an Austin, Texas fabless semiconductor company that designs radiation-hardened and extreme-temperature microcontrollers and microprocessors for aerospace, defense and industrial systems. Its patented HARDSIL process hardens standard commercial silicon against radiation and heat using conventional high-volume manufacturing, letting spacecraft, satellites and downhole tools run Arm Cortex-based compute in environments that would destroy ordinary chips.
ESS Technology, Inc.
ESS Technology is a privately held fabless semiconductor company in San Jose, California that designs high-performance analog and audio chips. It is best known for its SABRE line of digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), built on the patented HyperStream modulation architecture, which are widely regarded among audiophiles as some of the best-sounding audio silicon on the market. ESS parts power everything from LG flagship smartphones and Sennheiser's flagship headphones to home-theater receivers, professional studio gear, soundbars, and automotive audio systems.
Mauna Kea Semiconductors Corporation
Mauna Kea Semiconductors (MKSemi) is a Silicon Valley fabless chip company building what it calls the world's lowest-power ultra-wideband (UWB) technology - the short-range radio that lets phones, wearables, cars and IoT devices know precisely where they are and which direction they're pointing, down to a few centimeters. Founded in 2019 by semiconductor veterans and headquartered in Cupertino/San Jose with engineering hubs across China, MKSemi sells UWB chips, modules and SDKs, headlined by its highly integrated MK8000 SoC, to device OEMs and ODMs chasing precise location, secure ranging and radar-style sensing on coin-cell batteries.
