Keller Cliffton is the co-founder and CEO of Zipline, the world’s largest commercial autonomous delivery system. Before Zipline, Keller was a scientist at Harvard. Today, Zipline serves 5,000 hospitals worldwide, saves 10,000 lives per year, and has completed over 2 million drone deliveries – everything from food to medical supplies across Japan, five African countries, and multiple cities in the United States. In January 2026, Zipline raised a $600M round at a $7.6B valuation. The mission: put every person on the planet within 15–30 minutes of any product they need, no matter where they live.
