This week on Watt It Takes: How Ryan Popple’s experience in the military, Tesla and venture capital helped him lead electric bus maker Proterra.“It’s good for the ‘keep calm and carry on mentality’ when people tend to bring me a box of broken parts. So if you’re the founder or CEO of an organization, you shouldn’t be surprised when most of what is brought to you is bad news.”Proterra is on a roll. The company is a leading manufacturer of heavy-duty electric buses in North America, with over 50 customers, a one-year backlog and vehicles on the road in two dozen cities. The company’s current pipeline represents 10 percent of the US transit fleet.It took many years to reach this stage. Proterra faced numerous difficult technical re-designs and slow customer adoption over the last decade. In this interview, Popple reflects on how the company moved through the valley of death.
