How fast is Uber growing? Pretty darn fast -- CEO Travis Kalanick claims the company adds tens of thousands of new drivers every month. "There are hundreds of thousands of partners connected to our system," he said at TechCrunch Disrupt this morning. "We're in the neck of 50,000 new jobs every month that are being created." Kalanick admitted he didn't have the exact number, but that's a pretty massive increase. Back in May, the company said it was adding an average of 20,000 new drivers every month. You're not alone in thinking those numbers seem a little optimistic. By comparison, the entire US added 142,000 job in August, according to the Bureau of Labor Statistics' latest jobs report.
