# 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.

- **Founded:** 2018
- **Headquarters:** Seongnam-si, Gyeonggi-do, South Korea
- **Founders:** Hojun Kim (CEO & Co-founder)
- **Team size:** ~26 employees
- **Products:** SIRIUS, V2X-AIR, EDM (Ettifos Diagnostic Monitoring), OBU / RSU hardware, V2X IP & protocol stack
- **Notable:** World's first to commercialize a 5G-V2X software-defined modem (SDM) solution., Part of the first 3GPP Release 16 5G-NR sidelink radio interoperability connection (with Keysight and Autotalks, 2024)., V2X-AIR became one of the first V2X devices to be fully Build America, Buy America (BABA) compliant.

## Products & services

- **SIRIUS** — A future-proof C-V2X development and testing platform available in OBU and RSU configurations, built on a software-defined modem that can switch between LTE-V2X, 5G-V2X and beyond via software update. Complies with 3GPP Release 16 and lets researchers develop and validate use cases like forward collision warning, platooning, cooperative perception, and automated driving.
- **V2X-AIR** — A compact, plug-and-play onboard unit (OBU) for before-market and aftermarket vehicles and micromobility, supporting standards-compliant V2X services including tolling and safety. Now fully Build America, Buy America (BABA) compliant.
- **EDM (Ettifos Diagnostic Monitoring)** — A diagnostic and monitoring software tool for analyzing real-time performance of 5G-NR sidelink communication.
- **OBU / RSU hardware** — Onboard units and roadside units that form the two ends of a V2X network for connected-vehicle and smart-city deployments.
- **V2X IP & protocol stack** — RTL IP and V2X communication protocol stack IP, plus a C-V2X hardware accelerator chip in development on Samsung Foundry technology.
