It looks like Washio was operating in a lot of cities. None of the others are operating in more than two markets. They're all presumably burning cash trying to establish themselves in the market, but Washio was probably burning the fastest due to their rapid expansion. They also raised a little more money than the others, which probably encouraged them to expand faster. It's just a matter of time before the others run out of cash. They're all hoping that they'll be able reach the scale they need to turn a profit before the money train runs out. With Washio's closure, they must know that fundraising is going to be very hard, so you'll probably not see much more expansion in this space for a little while. Instead, they'll all work on increasing efficiencies and saturating existing markets, then try to leverage that into another round of funding to expand to more markets before the competition.
