Frances Frei, who was hired to fix what ailed Uber's broken culture and put its controversial CEO and co-founder Travis Kalanick on the right path, is leaving the company. She will be working on a new leadership development program for companies, aimed at women and underrepresented minorities, before returning to Harvard Business School.

You might imagine she got some pretty good examples for her work at Uber, which had been Silicon Valley's most obvious version of toxic culture. Not surprisingly, the ever-positive Frei did not see it that way, noting that the culture journey at Uber has been an important one.
