QuantumScape Q&A Series I

Recently, a few of our executives met to discuss some of the most common technical questions that we receive. We’re calling this the QuantumScape Q&A Forum and we plan on hosting more of these sessions to help inform the investment public about our progress and the key technical challenges that lie ahead.

Participants (clockwise from top left corner): John Saager, Head of Investor Relations, Tim Holme, Founder and CTO, Kevin Hettrich, CFO, and Jagdeep Singh, Founder and CEO.
