Detroit sent shockwaves across the country in 2013 when it made history as the first major U.S. city to file for chapter 9 bankruptcy.
For many Detroiters who saw the writing on the wall, it was a time of exodus — the Motor City's population has fallen every year since the end of the Great Recession, losing its place on the list of the 20 largest U.S. cities for the first time since 1850.
Fewer resources and fewer people downtown created a perfect storm for the city's already poor public transport system, particularly after plans for a solution — a $500 million, 9-mile light rail — were cancelled in 2011.
That was the breaking point for lifelong Detroit resident and serial entrepreneur Andy Didorosi, who had just launched his own automotive shop and business incubator after dropping out of engineering school. "I thought that if we can't figure out this little train, then we're never going to be able to make the rest of the city work," he said. "And so I bought a bus."
