S tanley Tang is a Hong Kong-born American technology entrepreneur who co-founded DoorDash, the largest food delivery company in the United States. He, along with his Stanford University classmates Tony Xu, Andy Fang, and Evan Moore, launched the company in 2013. The idea emerged from a small-scale experiment to build a website that displayed menus from local restaurants and offered a delivery service. This quickly proved there was a massive demand for on-demand food delivery, a market they would come to dominate.

As one of the key technical founders, Tang initially served as the company's Chief Product Officer, playing a crucial role in developing the sophisticated logistics software and the three-sided marketplace (connecting consumers, restaurants, and drivers) that powers DoorDash's operations. His engineering and product leadership were vital in scaling the platform to handle millions of orders daily. The company's highly successful initial public offering on the New York Stock Exchange in 2020 made the co-founders billionaires. He has since transitioned to lead DoorDash Labs, the company's robotics and automation division, focusing on future innovations like drone and robot delivery.
