The co-founders of Argo AI LLC announced the launch of a new autonomous vehicle firm based in Pittsburgh that secured financial backing from one of the world’s leading startup investors.

Stack AV, a firm with 150 employees led by CEO Bryan Salesky, President Peter Rander and Chief Technology Officer Brett Browning, has landed Japanese multinational investment holding firm SoftBank Group Corp. as its largest investor. The startup did not disclose the size of the investment from SoftBank, though sources familiar with Stack’s formation have claimed that the funding reaches hundreds of millions of dollars.

Established as an autonomous trucking business, Stack will look to address challenges relating to safety and supply chain obstacles that affect the road-based transportation and logistics industry, among other hurdles relating to efficiencies, driver shortages and vehicle uptimes.
