Eli David started StartupBlink to identify the best places in the world for start-ups. Despite it's well publicized problems dealing with homelessness and sanitary conditions, San Francisco is still number one. Then comes New York City, despite the best efforts of Comrade diBlasio to destroy it. Coming up at number 3 is London, hardly anyone's idea of a start-up. Eli is an economist and uses a number of measurements to compile his report. Coming up quickly from behind is Beijing and Shanghai. Will they one day be number 1 and 2?
