That is a new start-up. The purpose is to help your “sharing economy” reputation be portable across a number of sites, for instance Airbnb, DogVacay, Uber, Craigslist, and so on.
In my column from yesterday I speculated:
At the moment, one problem with many online ratings is that the information isn’t all publicly useful; for instance, a good Uber rating remains within Uber and cannot easily be exported to market a driver for other jobs or opportunities. Perhaps in the future workers might have the option of being certified by Uber or other services in a more general and publicly verifiable manner. That could make such services useful for upward mobility, and it might make their credentials competitive with those of some lower-tier colleges and universities.
I wish them luck…
