Sonnet.AI, DGIST’s first researcher-founded company, makes SonniX, autonomous-driving software installed on existing industrial vehicles. At POSCO it converted molten-iron locomotives to autonomous operation; they have run in production since 2023 and are now fully driverless. Its U.S. entity opened in San Jose in 2025.
What sets them apart
- One platform, any vehicle: the same software runs locomotives, forklifts and low-speed vehicles.
- Drives reliably indoors and outdoors, unlike most indoor-only AMRs.
- No site changes: no magnetic tape or reflectors.
Traction
- Driverless locomotives in production at POSCO.
- Deployed at HMMPSA, Busan New Port.
- First U.S. customer, a low-speed vehicle company in Los Angeles.
U.S. focus
Large industrial sites (steel, ports and auto plants), starting with smaller local businesses that run varied vehicle fleets.
Recognition
- Korea’s first SME autonomous-driving permit (2018)
