Lyft made a surprising move (although perhaps not to staff ) and announced its co-founders Logan Green and John Zimmer, who have been leading the company since its founding, are to make way for new leadership. David Risher, who is taking over as Lyft's CEO in mid-April, already has some ideas of how to reach profitability. In a with TechCrunch, Risher said the company may kill off shared rides and other features that get away from its core offering. And no, Lyft is not following Uber into delivery, so he says.
