LeddarTech is a Canadian automotive software company that develops AI-based sensor fusion and perception software for Advanced Driver Assistance Systems (ADAS) and autonomous driving. Its core product, LeddarVision, fuses raw data from multiple sensors — cameras, radar, LiDAR, and sonar — at the lowest possible level before any filtering occurs, building a 3D model of a vehicle's surroundings. LeddarTech calls this low-level fusion (LLF), and argues it outperforms older approaches where each sensor processes data independently before outputs are combined, resulting in better detection range, fewer false alarms, and improved reliability in bad weather or poor visibility. LeddarVision supports features like automatic emergency braking, collision avoidance, lane-keeping, and parking assistance. LeddarTech sells its software to automotive OEMs and Tier 1 suppliers, and is also pursuing off-road vehicle markets in agriculture, construction, and mining. The company is pre-revenue on its software business, working to convert 30+ active customer engagements into commercial design wins. Once an OEM selects LeddarVision for a vehicle program, LeddarTech expects to earn NRE fees during development, then per-unit royalties that scale with vehicle production volumes — the primary long-term revenue driver. LeddarTech originally sold LiDAR hardware, but exited hardware entirely in 2022 to focus exclusively on software, and went public via a SPAC merger.
