Unitsky String Technologies Inc. (uST), formerly known as and widely referred to as Rail SkyWay (RSW), is a private engineering and technology company founded by Anatoli Unitsky. The company's mission is to design, construct, and commercialize an innovative elevated transportation system called "string transport." This technology involves automated vehicles moving on high-strength, pre-stressed rails. Since its inception, the project has been primarily funded through a large-scale crowdinvesting or crowdfunding model, attracting capital from individual investors worldwide by selling shares or convertible notes in its parent entities.
