Uber's got 99 problems, but its steep losses aren't one -- at least in the eyes of investors.

The ride-hailing startup said Wednesday it lost $708 million in the first three months of the year. The financial data was paired with Uber announcing its search for a chief financial officer.

To many, the loss is nothing short of staggering. Jason Calacanis, an early Uber investor, congratulated the company on Twitter for continuing to grow while cutting its loss from the previous quarter.
