For better or worse, just about everybody has heard of Uber. Over the last few years, the ride-haling company has grown to dominate the market in the U.S. and beyond, currently operating in over 400 cities around the globe – despite significant resistance and outright bans in some places. DiDi, on the other hand, is unlikely to be on your radar. Having bought out Uber’s operations in China last year, the company currently enjoys 95 percent market share in its home country.
