42dot is a technology company pioneering frictionless transportation services. Central to these efforts is the development of the Urban Mobility Operating System (UMOS) a cloud-based mobility platform that will accelerate the transition to autonomous transportation-as-a-service (aTaaS) with diversified self-driving ground and airborne vehicles.

UMOS is a comprehensive platform with a functionality that spans all layers of the aTaaS stack: a user interface that provides access to connected mobility and lifestyle services, smart algorithms for fleet dispatching and management, cutting-edge extra-definition map and routing technology, and autonomous machines. Together, they create a centralized, fully autonomous, and self-managed mobility infrastructure of the future.

Through the development of UMOS, 42dot aims to improve the efficiency, safety, and convenience of the movement of people and goods. Above all, UMOS is designed to help people to focus on what is important in life.

42dot was founded by Chang Song in March 2019. The company headquarters is located in Seoul with a drone autonomy subsidiary, 42air, in San Francisco. The company raised 32 billion KRW (25 million USD) in pre-Series A funding from Korean conglomerates Kia Motors, SK, LG, and CJ including seed funding from Hyundai Motor Company. In June 2020, the company secured 17 billion KRW (14 million USD) from LIG Nex1, KTB Network, Shinhan Bank and IMM Investment.
