Top Artificial Intelligence Startups in California, US

Kodiak was founded in 2018 to redefine long-haul trucking using safe and reliable autonomous technology. Between growing e-commerce and a strong economy, demand for trucking is on the rise. The trucking industry faces major problems: a shortage of drivers, difficult working conditions, and extremely high turnover. According to the American Trucking Association, the industry faced a shortage of 51,000 commercial truck drivers at the end of 2017. Long-haul trucking is primed for autonomous technology. Highway driving is more structured and predictable than urban driving. This means there are fewer decisions for drivers to make and a better fit for autonomous vehicles. We believe that autonomous trucks will play a major role in filling the gap while improving safety, enhancing truck driver quality of life, increasing efficiency, reducing congestion and emissions and creating jobs across the economy.
