Looks like the quantified workplace is paying off in spades. Known as FitBit for employee-related goals, Palo Alto-based BetterWorks has doubled their workforce in the last six months. They're on a hiring spree, shopping for technical writers, product managers, support techs, and everything in between. A year ago, they had only six employees. When the app debuted in September, 2014, they had 27 employees. Since acquiring funding from Kleiner that same month to the tune of $15.5 million, they have jumped up to 40 employees.
