The Modem That Refuses to Stay Put: Hojun Kim’s Bet on Software-Defined Roads
After years designing chips, Hojun Kim is trying to make road infrastructure age more like software: upgradeable, interoperable and ready for the next radio standard.
Commsignia
Commsignia is a vehicle-to-everything (V2X) technology company that builds the software stacks, on-board units, roadside units and cloud platforms that let cars, road infrastructure and traffic operators talk to one another. Founded in Hungary in 2012 and now headquartered in Santa Clara, California, the company supplies standards-compliant C-V2X and DSRC solutions used by automakers, road operators and departments of transportation across more than 20 countries, with the goal of reducing collisions and smoothing traffic flow under the banner 'Trust for the road ahead.'
Ettifos
Ettifos is a South Korea-based, 5G-focused V2X (vehicle-to-everything) company building the communication layer that lets cars, roadside infrastructure, and pedestrians exchange safety and traffic data in real time. Its flagship SIRIUS platform uses a software-defined modem that can switch between LTE-V2X and 5G-V2X with a software update, and its plug-and-play V2X-AIR onboard unit brings standards-compliant connectivity to both new and existing vehicles. Founded in 2018, the company works with partners like Keysight, Autotalks, Audi, and Kapsch TrafficCom, and closed a Series B round in 2025 to scale a C-V2X hardware accelerator chip and expand into U.S. and European markets.
Seyond
Seyond (formerly Innovusion) is a Sunnyvale-based maker of image-grade LiDAR sensors and perception software for autonomous vehicles, ADAS, smart infrastructure, robotics and industrial applications. Best known as the long-range LiDAR supplier behind NIO's ET7, ET5 and ES7, the company has shipped more than 250,000 Falcon units and is pushing solid-state designs into mass production.
Jozsef Kovacs
Jozsef Kovacs was the co-founder and CEO of Commsignia, the world's largest company fully dedicated to Vehicle-to-Everything (V2X) communication technology. Born in Hungary and trained as a computer scientist and PhD researcher in cooperative intelligent transportation systems, he co-founded Commsignia in 2012 alongside fellow researchers from the Hungarian Academy of Sciences. Under his leadership, Commsignia deployed V2X technology across 130+ intersections in Las Vegas, secured partnerships with Volkswagen, Audi, Ford, and major OEMs, raised $26M+ in venture funding, and expanded to 20+ countries. Kovacs passed away in late 2021, leaving behind a company that continues to lead the global V2X industry.
Junwei Bao
Junwei Bao is the co-founder and CEO of Seyond (formerly Innovusion), a Silicon Valley-founded LiDAR company that went public on the Hong Kong Stock Exchange in December 2025. With a PhD in Electrical Engineering from UC Berkeley and a physics background from Peking University, Bao spent nearly two decades building precision optical sensors before pivoting to autonomous-driving hardware. He co-founded Timbre Technologies - the company that invented OCD (optical critical dimension) scatterometry, a kind of microscale LiDAR for semiconductors - then led Baidu's autonomous driving hardware division before founding Innovusion in 2016. Under his leadership, Seyond delivered 230,000 automotive-grade LiDAR units in 2024 and holds a 12.8% global ADAS LiDAR market share, ranking fourth worldwide.
