Beijing: Chinese autonomous driving start up DeepRoute.ai on Tuesday said it has raised $300 million from investors including the e-commerce company Alibaba To expand its test fleet and develop technologies including self-driving trucks.

Other investors in the funding round include Greater China-focused tech investor Generation Capital, Chinese automaker Geely and some previous investors, deeproot.ai said in a statement. It did not disclose its valuation.

The investment comes as automakers and technology firms are plowing billions of dollars into autonomous driving, a goal that many see as the future of mobility.

DeepRoute.ai’s rival WeRide, backed by Nissan Motor, said this month it would develop self-driving vans, while Pony.ai, backed by Toyota Motor, had earlier said it would develop autonomous trucks.

DeepRoute.ai, which has been testing vehicles in the Chinese cities of Shenzhen and Wuhan, will use the funds to double its test robo-taxi fleet from the current 70 to 150 by the end of this year, said its chief executive Zhou. Guang told Reuters in an interview.

It will increase its workforce to 600 by the end of this year, including vehicle safety drivers, from 400 now.

Founded in 2019, DeepRoute.ai collaborates with automaker Dongfeng Motor on self-driving technologies. It also works with Geely’s ride-hailing unit Cao Cao.

Deeproot.ai will also develop self-driving light duty trucks for urban logistics services, Zhou told Reuters, adding Alibaba will be a big customer.

Alibaba said in June that it plans to develop self-driving trucks with its logistics subsidiary Caniao.
