When I worked at Google Ventures, one of the best parts of the job was spending time with founders as they built their businesses; I remember meeting with Keller Rinaudo, Zipline's founder and CEO, more than a year before their first delivery in Rwanda.

Later, I remember hosting Zipline in a meeting with a F500 CEO client who wanted to explore partnering with them. Something Keller said in that meeting has stuck with me ever since.

Watching this video brought it back. He talked about the Zipline delivery centers, and the fences surrounding the launch / landing zones. And how most days, there were kids who'd hang out by the fence to watch the drones take off and land.

“What will the future they create look like, when things like life-saving blood from the sky were just a normal part of their childhood?”

I think about that a lot. And it makes me hopeful.
