Netradyne, an artificial intelligence startup founded by two former Qualcomm executives, has raised $21 million in new funding Thursday to push forward the company's technology for commercial fleets. The new round of cash was led by Microsoft's corporate venture arm, M12, along with Reliance Industries, and Point72 Ventures. Reliance, based in India, previously invested $16 million in Netradyne's Series A. The San Diego company, founded in 2015, makes a sophisticated monitoring technology that can keep an eye on commercial vehicle fleets while on the road. The startup's small device mounts behind a rear-view mirror and acts as a computerized command center to capture 360-degree video of a vehicle's surroundings. The tool uses Netradyne's AI software to figure out if drivers are operating safely or not, picking up things like tailgating, speeding and getting in accidents.
