# Terraline

> Terraline is a Bay Area vehicle technology company founded in 2021 (originally Solo Advanced Vehicle Technologies) by ex-Tesla and Waymo engineer Graham Doorley. It set out to decarbonize freight with a clean-sheet, battery-electric Class 8 long-haul truck, the Tangra LH1, boasting 500+ miles of range and the lowest drag coefficient of any Class 8 truck. The company has since evolved toward a software-defined vehicle (SDV) platform - a central compute system, cloud telemetry, and an AI backend - aimed at modernizing the electronic architecture of heavy machines.

- **Founded:** 2021
- **Headquarters:** Fremont, California, United States
- **Founders:** Graham Doorley (Founder & CEO)
- **Team size:** ~26 employees
- **Products:** Tangra LH1, SD1, Central Compute System (CCS), Terraline Stream, AI-Driven Backend
- **Notable:** Designed and built the SD1 clean-sheet Class 8 battery-electric truck prototype, Successfully completed first battery-electric drivetrain and drive-by-wire tests in 2022, Raised $7M seed in 2022 led by Trucks Venture Capital

## Products & services
