Supplanting an incumbent industry that has defined mass transportation for over a century is no easy task, but that’s exactly Proterra’s mission as it seeks to replace every fossil fuel and diesel-dependent bus in North America with its zero-emission, battery-electric buses.

Designed from the ground up as purpose-built, lightweight electric buses, the Proterra Catalyst boasts the highest efficiency rating in the transit market and has demonstrated exceptional performance across a wide variety of North American terrains. More than this, they cost significantly less to maintain and operate than diesel, diesel-hybrid, and CNG over a bus’ expected 12-year lifespan. With this dollars-and-cents argument combined with the buses’ state-of-the-art performance, Proterra has established itself as a major player in the transit industry, winning over 5% of new bus sales in 2016.

In 2016 alone, Proterra was featured in over 350 articles in both trade and top-tier publications ranging from the Wall Street Journal and Fortune to Forbes and Bloomberg. CEO Ryan Popple was also cemented as a highly sought-after thought leader in Silicon Valley and beyond, appearing on television programs like Bloomberg TV as well as industry-spanning events like the American Public Transit Association Annual Conference and SXSW Eco. The company also had an oversubscribed Series 5 equity financing round, raising more than double what it had set out to secure and capping the round at $140M.
