Hesai Group is a Chinese hardware company specializing in lidar, a remote sensing technology that uses laser pulses to measure distances and reconstruct the environment in three dimensions. Its sensors are used notably in vehicles and robots that need to detect obstacles, identify objects and determine their position. Based in Shanghai, the group operates at the intersection of optics, electronics and embedded software, with one central challenge: turning a complex measuring instrument into a component suitable for mass production.
A growth trajectory driven by autonomous mobility
Founded in 2014, Hesai grew by addressing machines’ perception needs, with a strong focus on autonomous vehicles. Robotaxi operators and developers of automated driving systems provided an early market for lidar sensors capable of producing a detailed representation of their surroundings. The company subsequently expanded its offering to meet automakers’ requirements in terms of size, reliability, integration and cost.
In 2023, Hesai Group was listed on Nasdaq under the ticker symbol HSAI. This listing gave greater international visibility to a manufacturer whose operations remain firmly rooted in China. Its trajectory parallels that of China’s intelligent vehicle industry, which brings together automakers, automotive suppliers, battery specialists and sensor providers.
Sensors for cars and robotics
Hesai’s portfolio covers several lidar applications. Some products target long-range perception, which helps anticipate obstacles on the road; others address the need for close-range coverage or integration into robotic platforms. The group supplies both autonomous driving companies and automakers incorporating advanced driver assistance features into production vehicles.
However, a lidar sensor is not an autonomous driving system on its own. Its data must be interpreted by software and can be combined with data from cameras and radar sensors. The sensor’s value therefore depends as much on its measurement performance as on its ability to operate in varied conditions, integrate into the vehicle’s architecture and meet automotive qualification requirements.
For Hesai, control over design and manufacturing is a critical issue. Moving from small production runs for experimental fleets to automotive-scale volumes requires consistent quality, secure supplies and lower production costs.
What next?
The next stage will depend on the role automakers give lidar in their perception architectures. Hesai must contend with competition among suppliers, decisions favoring systems that rely more heavily on cameras and pricing pressure in China’s automotive market. Internationally, trade restrictions and security concerns surrounding Chinese technologies add uncertainty. The challenge will be to turn customers’ technical choices into lasting industrial programs while diversifying into markets beyond the automotive sector.
